ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

20 LITERATURE REVIEW
21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

20 LITERATURE REVIEW
21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)

The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

20 LITERATURE REVIEW
21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

20 LITERATURE REVIEW
21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

20 LITERATURE REVIEW
21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

20 LITERATURE REVIEW
21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

20 LITERATURE REVIEW
21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on

221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic

This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants

Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

20 LITERATURE REVIEW
21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth

been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al

is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

10 INTRODUCTION
11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

ABSTRACT
Annona muricata Linn is known for its medicinal uses and the demand for the fruits and even
the leaves is increasing yearly However due to poor seed germination and low viability an
alternative propagation techniques is critically needed A study on vegetative propagation by
stem cuttings of A muricata was conducted in the greenhouse and near the Plant Propagation
Laboratory at Universiti Malaysia Sarawak (UNIMAS) The aim of this study are to determine
the effect of different concentration of Indole-3-Butyric Acid (IBA) treatment and different age
of stock plants of A muricata on rooting propensity Vegetative propagation through stem
cuttings is an effective way to produce true-to-type seedling for large scale plantation and short
the juvenile phase of plant In this experiment three different ages of stock plant 1 year coppice
shoot 2 years old and 15 years old tree were used Five different concentrations of IBA were
used in this study [0 mgL 100 mgL 200 mgL 400 mgL and 1000 mgL (SADEX no1)]
Stem cuttings taken from 1 year old coppice shoot produced the highest rooting success (47)
while cuttings from 2 years stock plant was the second has the highest rooting but they
produced the most roots The untreated stem cuttings treated (Control) produced highest rooting
success (433) and number of roots formed (6636plusmn0342) However the application of PGR
is still vital to enhance rooting in A muricata

11 Research background
Annona muricata L or soursop is a tropical fruit trees belong to family Annonaceae which
there are approximately 199 species (Badrie amp Schauss 2009) Four of this species are known
as bearers of edible fruits which are custard apple (A reticulata Linn) the sugar apple or
sweetsop (A squamosa Linn) the cherimoya (A cherimola Mill) and the forth species the
subject of this paper is soursop (A muricata L) which is the tropical the largest fruits and the
only one leading itself well to preserving and processing (Morton 1966) and grown for
domestic or commercial value
The tree of soursop is low branching and bushy but slender and can reach a maximum of 25 or
30 ft in height while leaves are alternate normally evergreen smooth glossy and oblong
elliptic or narrow-obovate in shapes The colour of leaves are dark green on the upper surface
and lighter at beneath and produce an aromatic smell when crushed the leaves (Morton 1966)
The flowers may emerge everywhere on the trunk branches or twigs and borne singly Next
character the fruit of A muricata is more or less oval or heart-shaped and the weigh can be
reach up to 7 kg (Orwa et al 2009) and covered with a reticulated inedible soft pliable
ldquospinesrdquo (Morton 1966) For the immature fruit the skin is usually dark-green becoming
slightly yellowish green before the fruit is soft to touch The seeds of A muricata is oval
smooth hard and black in colour
A muricata can survives in the humid tropical and subtropical lowlands and common on the
coast and is found on slope Besides it becomes wild or naturalized in thickets pastures and
along the roads This species fairly common cultivated in home gardens and is found in the
rural garden areas on volcanic and raised limes tones island (Orwa et al 2009)
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied

232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from
2
The soursop fruit consists of 675 edible pulp 20 peel 85 seeds and 4 core by weight
and the white edible pulp contains 80ndash81 water 1 protein 18 carbohydrate 343
titratable acidity 245 non-reducing sugar and vitamins B1 B2 and C (Badrie amp Schauss
2009) Fruits of A muricata are extensively used to prepare syrups beverages candies and ice
cream and shaker (Patel amp Patel 2016) Other parts of the trees such as leaves bark roots and
flowers have been used medicinally in many tropical African countries array of human illnesses
especially for parasitic infections and cancer (Eggadi et al 2014)
Due to its potential uses the demand for this species in increasing yearly To overcome this
problem A muricata are propagated by stem cutting because the process by rooting of cutting
can produce true-to-type seedling for large scale plantation and the juvenile phase of plants can
be shorten (Haapala 2004) Large planting has been started in the South and North America
and is now widely distributed throughout tropical and subtropical parts of the world including
Malaysia Africa Nigeria and Australia (Patel amp Patel 2016) This species also can grow from
seeds but propagation of most Annona species through seed is not recommended as the seedling
are genetically diverse take a long juvenile period irregular bearing and poor fruits quality
(George amp Nissen 1987)
12 Objective
Therefore this study was carried out with the following objectives
1 To determine the effect of age of stock plant on rooting propensity
2 To study the effect of the different concentration of Indole-3-Butyric acid (IBA) for the
rooting formation

20 LITERATURE REVIEW
21 Botanical Description
Annona muricata commonly known as soursop or guanabana is a tropical fruits trees belongs
to family Annonaceae (Lemos amp Baker 1998) This species is an evergreen tree upright and
low branching tree reaching up 8 to 10 meter (Badrie amp Schauss 2009) The leaves are simple
alternate smooth glossy and the leaves are green on the upper surface and paler and dull on
under side with fine lateral nerves (Orwa et al 2009) The shapes of leaves are oblong elliptic
or narrow to obovate pointed at both ends and highly aromatic when crushed (Morton 1966)
Yet as mention by Morton (1966) in his writing the flowers of A muricata are borne singly
and may appear everywhere either on the trunk branches or twigs and the fruits shaped are
more or less oval or heat-shaped and sometimes irregular and the fruits also are covered with
curved and soft pliable ldquospinesrdquo The pulps of this fruit is white fibrous and juicy and easily
separated from the inner skin when the fruit is fully ripe Seeds are oblong dark brown or black
in colour and shiny (Orwa et al 2009)
The A muricata trees are native to tropical Central and South America and the Caribbean and
because of the high demand of the A muricata today it is widely cultivated in tropical areas
worldwide including southern Florida and Southeast Asia from sea level to altitudes of around
1150 meters (Patel amp Patel 2016) This species can survives in the areas of humid tropical and
subtropical level and it is common on the coast and is found on slopes (Orwa et al 2009) At
the temperature below than 5˚C it will leads to damage of the leaves and small branches and
can be fatal when the temperature below than 3˚C (Patel amp Patel 2016) As mention by Orwa
et al (2009) in his writing A muricata is commonly cultivated in home gardens and is found
in the rural garden areas on volcanic and raised lime stones islands where it is occasionally
naturalized

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use

genetic characteristics by producing better or worse plant genetic than their parent plants

produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)

are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen

Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages

sucker corms and others Artificial propagation such as cutting micropropagation grafting

this process The first advantages of asexual is able to maintain the similar genetic

This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from

22 Economic importance
221 Food uses
A muricata can be consumed fresh for the dessert when fully ripe (Orwa et al 2009) Soursop
are distinguished into two types at El Salvador which are sweet (guanabana azucaroacuten) eaten
raw and used for the drinks and very sour (guanabana aacutecida) that are used only for the drinks
(Morton 1966) The soursop is sold as fresh or frozen pulp strained soursop juice and frozen
concentrates which have been preserved as various juice blends ice creams sherberts nectars
syrups shakes jams jellies preserves yoghurts and ice creams and syrup (Badrie amp Schauss
2009) In Cuba and Brazil peoples there make the refreshing drinks by mixing the fruit with
milk and sugar while in Puerto Rico it is generally mixed with water (Badrie amp Schauss 2009)
In the Philippines the immature fruits with seeds that are still soft are cooked as a vegetable
5
and for the matured fruit but firm it may be used to made into candy of delicate flavour and
aromatic (Orwa et al 2009)
222 Medicine
Many of folkloric uses have been scientifically validated since the 1940s (Badrie ampSchauss
2009) In India A muricata are widely used as medicine to treat the kidney disease fever ulcer
and wounds The leaves of the A muricata also can be used as suppurative and febrifuge (Badrie
amp Schauss 2009) and in the Netherlands Antilles the leaves are put into the ones pillowslip or
strewn on the bed to promote a good nightrsquos sleep (Morton 1966) Badrie and Schauss (2009)
state that in their book fruits and fruit juice is used for fever parasites and diarrhea and it also
good for pregnant women because it can increased the motherrsquos milk (lactogogue) Most of the
countries like India Brazil and Guianas they use leaves or either bark of A muricata to
prepared the pleasant drink in the evening ldquoteardquo that are good as antispamordic sedative and
for diabetes At the earlier of the introduction of this species it became basis of folk medicine
system throughout the word for thousands of years and now are continue to provide the mankind
with new remedies (Patel amp Patel 2016) Generally this species are rich with annonaceous
acetogenins compound (AGEs) which play a key role towards many varieties of cancer and
acetogenins are potent inhibitors nicotinamide adenine dinucleotide phosphate-oxide (NADH)
of the plasma membranes of cancer cell (Patel ampPatel 2016) It has been reported that the main
antitumorous compound annonacin was effective against various in vitro cancer cell lines as
well as in vivo lung cancer Nowadays even without any scientific validation many cancer
patients and health practitioners are adding the natural leaf and stem of A muricata as a
complementary therapy to their cancer protocol (Eggadi et al 2014)

23 Propagation techniques
Basically plant can be propagated by sexual and asexual For A muricata itself both methods
have advantages and disadvantages
231 Sexual propagation
Sexual propagation is a nature process that involves contribution between both male and female
plant to produce the new plants that are genetically similar or different from them The process
of sexual propagation started with flowering pollination followed by fertilization and then
seeds germination Through this propagation it will produce the large number of offspring in
the short period of time and can be handle in the large number easily but the seedling that are
formed may have the better or worst characteristic than the parent tree (Kumar et al 2007)
Because of that reason the genetic quality is hard to be maintained by using sexual propagation
(Shivanna Balachandra amp Suresh 2007)
232 Asexual propagation
Asexual propagation also known as vegetative propagation that involves production of species
through natural and artificial propagation For natural propagation the plant will be produce
the new plant through vegetative parts of plants such as bulbs tuber runner or stolon rhizome
sucker corms and others Artificial propagation such as cutting micropropagation grafting
budding and air layering also are various methods of asexual propagation process Crops that
do not have possess seeds or the crops which are possible to grow from seeds are allows to use
this process The first advantages of asexual is able to maintain the similar genetic
characteristics of the individual plats (Firmansyah 2007) compared with sexual propagation
This is due to new plants produces from sexual propagation may not necessary to have similar
characteristics with their parents plant because open fertilization may change their original
genetic characteristics by producing better or worse plant genetic than their parent plants
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud

the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful

2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
2324 Stem Cutting
Cutting is the process of removed the part of plant from the parent plant and rooted to form the
new plants There are four types of cutting can be classified which are stem cutting leaves
cutting leaf-bud cutting and root cutting Stem cutting is the most commonly used method of
cuttings The part of stem that are injured respond by the forming of the callus at the part that
9
are injured Cell near the callus reorganized and differentiated to form adventitious roots
(Biswas amp Kobayashi 1995) Usually cuttings are collected early in the morning in order to
reduce the loss of water in the plant through transpiration The succession of cutting is depend
on the various factor that play very importance role to ability of rooting
24 Factor affecting rooting of cutting
There are several factors known to affect rooting of stem cuttings such as effect of PGR
concentration age of stock plant leaf retention position of cutting temperature light and
length of cutting Different species produce different response However for the purpose of the
review only the effect of PGR concentration and the age of stock plant are elaborated
241 PGR concentration
PGR is synthetic plant hormone or plant growth regulator basically PGR are not nutrient for
the plant but it is plant chemical at low concentration that promote and affect the growth
development and differentiation of cells and tissues (Wiesman et al 1989 Anon 2012) For
stem fully developed leaves and roots cutting is accomplished by using auxin that are a class
of phytohormones which are involves in many aspect of growth and development of plant (20)
The first plant hormone that are used to stimulate rooting of cutting is Indole-3- acetic acid
(IAA) but it is covered that a new synthetic auxin Indole-3-butyric acid (IBA) also promoted
rooting and more effective than IAA (Zimmerman amp Wilcoxon 1935) Nowadays IBA is an
important auxin that are commonly used to root many plant species Since IBA has been
introduced due to its effectiveness in promoting root initiation of a large number of plant species
and its general lack of toxicity over a wide concentration range (Richardson et al 1979) it has
been the subject of many experiments mostly involving trials and errors studies of different
concentration formulations additives and treatment durations to achieve optimum rooting for
the plant species in question (Muumlller 2000)
10
The stimulatory effects of IBA in rooting of stem cutting of several other woody plant species
have been reported by other workers and they revealed that IBA has an important roles in the
development of adventitious root improving quality of roots increasing rooting percentage and
uniformity in rooting of cuttings (Husen amp Pal 2007) Ahmad (2010) mentioned that 100 mgL
of IBA was the best PGR to enhance rooting for Aquilaria macrocarpa Bail while Nasri et al
(2015) suggest that the cutting treated with 1000 mgL overcome the problem of the difficult-
to-root Husen amp Pal (2007) reported the root formation process in cuttings of Tectona grandis
is increased by IBA which influences polysaccharide hydrolysis resulting in increased content
of physiologically active sugar needed to provide energy for meristematic tissues and later for
root primordial and root formation However the way plants behave when treated with the
chemicals depends on the kind of growth regulator used and on the amount and way it is applied
(Mitchell nd)
242 Age of stock plant
The ability of cutting to form the roots is affected by the age of the propagative materials from
which it is taken This has seen to be a major influence on successful propagation rather than
the treatment of the propagation material after it has been isolated The age of cutting trees can
be divided into two groups which are juvenile and mature trees There is a lot of evidence to
support that the ability of cuttings to produce adventitious roots decrease with the increase of
age of plant According to Haapala (2004) old plant is usually more difficult to multiple
compare to juvenile characteristics Awang et al (2011) Darus et al (1990) Raviv et al
(1987) mentioned that the rooting percentage declined with increasing age of stock plant Older
or mature plants have low rooting ability while juvenile stock plants have higher rooting ability
Thus increasing age of plants may decrease the root length survival rate and rooting speed of
cutting Pottinger and Morgenstern (1984) found that the percentages of cuttings taken from
7
Secondly asexual propagation can shorten the flowering time especially grafting and budding
and can bear fruits early than sexual propagation By this propagation the juvenile phase of
plants is able to be shorten (Haapala 2004) Besides asexual propagation is able to combine
more than one genotypes into a single quality plant Two or more different genotype plant under
the same genus or species can be propagated or combined to form a better plant This types of
propagation is economically least expensive than sexual propagation in long term and this
techniques are less complicated to exercise
2321 Micropropagation
Micropropagation is production of plant by growing small plant parts aseptically in a container
where the nutrition and environment can be controlled Small plant part or also known as
explant that can be used in micropropagation is root segment leaves segment buds meristem
cotyledon and stem segment The method or technique that are used in micropropagation is
called plant tissue culture or plant in vitro culture technique Two importance principle in this
technique is totipotency and hormonal regulation of organogenesis This technique provides
alternative to seedling heterozygosity space quantity and time consideration (Jaskani et al
2008) Besides it is also expensive in term of preparation of cutting and price of the cutting
produced (Haapala 2004 Jaskani et al 2008)
In addition from that professional skill and expertise labour also required to produce high
quality of explant Generally this types of propagation helps a lot in agriculture and forestry and
it can produce genetic alteration to improve the quality of the crop and products like producing
disease resistance climate tolerable and high yield of fruits plants (Jaskani et al 2008)
2322 Budding and grafting
Grafting is the process of connecting two plant parts a stem and a root together in such a way
that they will unite and continue to grow as one plant A grafted plant consist of scion and stock
8
Scion is a short piece of stem and shoot with two or more bud that will be produce stem and
branches while stock is referred to understock or rootstock which is the lower portion root or
growing plant of graft (Sagers 2005) The cambium layer of scion must be contact with the
cambium layer of the stock plant for the successful growth of the graft There are several types
of grafting such as whip wedge cleft bark bridge and approach grafting The process of
budding also similar with grafting except that the scion is reduced to a single bud with a small
portion of bark or wood attached then the single bud scion is joined with the rootstock to form
the new plant Budding process is easier faster and more economical than grafting To produces
the successful of budding the rootstocks should be healthy and good growth habit have a good
root systems and resistance to soil borne disease while the scion must free from harmful
pathogen and from well develop and active growing bud
2323 Layering
Air layering is the process of rooting the new plant while the stem is still attached to the parent
plants (Geoge amp Nissen 1987) This method usually used when seeding grafting cutting and
the other methods of asexual propagation is ineffective and may be made at any part of stems
on proper maturity Application of rooting promoting substances during the layering process
helps to get adventitious roots within a short period Initial studies on rooting seedling of
cherimoya lines using a modified layering technique have been highly successful The excellent
root systems are produced in four to five month (George amp Nissen 1987)
