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

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

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

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

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

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)

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

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)

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

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

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

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

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

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

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

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

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

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)

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

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)

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

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

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

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)
