ABSTRACT: This plan has been done in farming year 2009 with the purpose of precise
recognition life stages and determination of end time of supplementary BBCH stages and plant
height in every stage on three sunflower cultivars Hisson 33(V1), Record (V2), and Progress (V3)
in research and Educational farm of Damghan. The results indicated that height growth of Record
Cultivar was quicker than two other cultivars. At the end of first stage, the height of Record
cultivar was more than other cultivars on the same date, that is, increase in the growth rate of
cultivar at this stage. The main differences between this cultivar and two other cultivars were
started from this stage. Stem elongation starts at third stage and internodes become visible, at this
time the difference was observed among cultivars. Record cultivar showed quick elongation
growth at this stage and had more height at the same date of taking statistic. Finally this difference
of elongation growth speed caused in variation of height average about 8 Cm among Record andProgress and Hisson 33 Cultivars. This matter was observed in the end of growth stages. So that
Record cultivar with more height reached its own final growth with shorter time that was an
indication of more early ripening of this cultivar in comparison with two other cultivars.
According to obtained BBCH results, it is considered that the timing of fertilizing, irrigation and
weed control in Record cultivar which is early ripening must perform in different time in
comparison with other cultivars.
Key words: Phenological Stage; Sunflower; BBCH Scale
Introduction
With rapid growth of population providing
alimentary needs is one of the most importanthuman problems on the earth (Alyari, 2000). One
of the main nutritious products that our country
always has faced problems in providing internal
needs is edible oil (Arshi, 1992). Oily seeds such
as canola (brassica napus L.), cotton seed,
sunflower, and Glycinmax are the most important
products containing vegetative oil which have
special positions in agriculture and vast areas are
allocated to culture these valuable products
throughout the world (Langham, 2007). Sunflower
(Helianthus annuus) is a yearlong plant of
Astraceae family that grows in the form of astable bush (Hashemi Dezfooli et al, 1995). In
addition to, recognition of phenological stages can
completely provide transferring of common
concepts in studying the effective factors on final
performance so the results are presented according
to orderly and scientific method (Mulkey et al,
1987). The first study about phenological stages
of plants growth was done in 1974; it considered
the recognition of distinctive main and general
stages of growth in cereals, especially in wheat

and its condition description (Agusti et al, 1997).
This theory was expanded later, so that,
parallelism code was obtained for other farmingplants and weedy grasses with presenting research
projects, growth stages of plant were determined
and examined by using them (Cautin and Agusti,
2005). The BBCH code is included as a check list
in several IT-Systems for reporting and analysis of
agricultural field trial data. ARM and PIAF
(Gyllng and Stratmann, 2007;Michei et al. 2007;
Schmidtke and Zink, 2007) are two commercial
systems in which the BBCH coding system is
integrated as check lists.The Guidelines for Plant
Phenological Observations of World Meteorologi-
cal Organization (WMO) highly recommend the
phase definition according to the BBCH codes in
a chapter of its own (Koch et al., 2007). The
Global Phenological Monitoring programme (In-
tern. Society of Biometeorology) is fully
compatible with the BBCH system. The
International Phenological Garden and many other
national programmes provide a compar-European
Phenological Data Platform for Climatological
Applications (COST 725) hosted by the Austrian
Central Institute of Meteorology and
Geomagnetism (ZAMG) in Vi-enna manages its
phenological data using the corre-sponding BBCH
codes (Koch et al., 2006). Decimal planning
system was suggested and used for explaining
different growth stages of farming plants byBBCH general scale (Weber et al, 1990). This
scale was designed based on the system proposed
by Zadoks (Zadoks et al, 1974; Weber et al,
1990). Based on Zadoks system different private
methods were spread for each product separately
(Lancashire et al, 1991). Then Hack and his
colleagues (1992) published more exact and
extensive description of previous system with the
term of supplementary and general BBCH
method. This scale was organized in 10 main
stages of growth that every one of them contained
secondary growth stages on their own part. It can
state all stages of plant growth from germinationto aging and harvesting in the form of 2-digit
codes for every of two groups of single and
double shoots (Hack et al, 1992). Attibayeba
described growth phenological stages of sesame
plant using developed BBCH criterion and
concluded that using this type of system is able to
answer to many questions about the effect of
different environmental factors on farming plant
growth (Attibayeba et al, 2010). Jalilian and his
colleagues (2009) studied sunflower growth stages
in dry conditions based on description of
sunflower growth stages and they concluded that
dry tension caused time decrease of growth stages
(Schneiter and Miller, 1981). In Jafari andcolleagues experiment (2006) about the effect of
aggregation on sunflower phenological stages
period length from culture to transferring
meristem from growing to natal, culture to
pollination, seed fill period to physiologic ripe
were not influenced by aggregation. In Fanaee and
his colleagues (2006) the effect of late cultures on
colza phenologic stages, it was determined that
the effect of culture date of cultivar was
significant on height and the number of cantina on
the bush. Poor Esa and his colleagues (2006)
examined the effect of culture date on the length
of colza phenology stages. The statistical results
indicated that there is a significant difference
about 1% among the levels of culture date and
cultivar on the part of phenological stages such as
period of growth stage, the number of required
days from culture to sprout appearance,
Inflorescence period length, and seed fill period.
The length of these periods was decreased by
delay in culture date.
Materials and Methods
This study was conducted with the purpose of
exact identifying of life stages and determining of
end date of supplementary BBCH stages (fromculture to harvest time) and plant height in each
stage on three sunflower cultivars including
Hison33, Record, and Progress in research and
educational farm of Rasool-e-Akram Educational
center in Damghan. The zone geographical
characteristics have been prepared in table 1 and
statistic of warmth degree, humidity, and
precipitation of Damghan city in experiment year
are provided in table 2. The land was plowed
completely and was soft by Cultivator and disc.
The farm was fertilized by 150 Kg Ammonium
Phosphate before culture and 200 Kg urea in two
stages in sifted form (the second stage was donebetween culture lines in linear form). Point
distance from each side was 2 meters and each
block distance was 4 meters. Culture distances
were 6020. Culture type was done on the rows in
the dry culture. Phenology stages were examined
based on sunflower BBCH stages.
Results and Discussion
The extended Biologische Bundesantalt and
CHemische (BBCH) scale and its associated

decimal code were used to describe the different
growth stages of Sesamum indicumL. The study
focused on different primary and secondary plantgrowth phases from germination to senescence.
The use of a two-digit decimal code allowed the
identification of the principal growth stages and
their respective secondary stages. This approach
suggests that this could be of great help to sesame
growers and researchers for efficient planning of
both management practices and experimental
designs ( Attibayba et al, 2010). Developed
BBCH indexes contain 10 stages of principal
growth that have been numbered from 0 to 90
(Weber L. and G. F. Bleiholder(a), 1997). Stages
are considered from dry seed or zero stage for all
farming plants which propagate from seed and
stage 1 are considered for plants that are cultured
from slip or graft form in farm (Hess et al, 1997).
BBCH stage 2 is not described in one- branch
plants that dont have lateral branches thanks to
lateral branches are only described at stage 2
(Weber L. and H. Bleiholder(b), 1990). Growth
stages finished at stage 4 which include
development of growing parts that are harvestable
and plant has maximum content of protein in
forage plants because crop harvest is done at this
stage (Attibayeba et al, 2010). But growth stages
continue till the final stage or stage 9 in grains and
oily plants. Stage 4 is not described for these
plants because crop harvest will not be at thisstage (Weber L. and H. Bleiholder(b), 1990).
Obtained results are presented at table 4 and 1 to 8
figures. The BBCH scale is a contribution to
improve the communication between different
groups of scientists and to allow the interchange
of data and scientific results in a transparent way
(Meier et al, 2009). As it is showed in the table
there isnt any difference among cultivars at
BBCH zero stage that starts from dry seed and
finishes to cotyledons emergence toward soil
surface. All cultivars have finished this stage
during 16 days. Also plant height didnt show any
difference among these cultivars at the end of thisstage (Fig. 1). Subsidiary stage from zero stage is
called respite stage (Hess et al, 1997). After that,
swelling and water taking stages are done.
Propagation seed of these stages are similar for all
plants. At stage 1 principal event is leaf
development on the main branch. As you can see
in the table Record cultivars height is more than
other cultivars at the end of stage 1 on the same
date that means growth rapid speed at this stage.
The main difference between this cultivar and two
other cultivars begins from this stage (Fig. 2). The
number of leaf pair is different among various
species at stage 19. For example, Polygonum
aviculare has two real leaf pairs at the end of stage12, while four real leaf pairs are seen in Lamium
amplexicaule at the end of this stage (Hess et al,
1997). Stage 10 begins with real leaf first pair
emergence for cotyledons for monocotyledon
plants, but this stage begins with complete
development of cotyledons in dicotyledons and
initiates by separation of first leaves from each
other in bushes and trees (Hess et al, 1997). Stem
growth starts and internodes become visible at
stage 3; the difference was seen among cultivars
at this stage like previous stage. Record cultivar
showed more length growth speed and had more
height at the same statistical date (Fig. 3).The
BBCH scales allow the comparison of individual
codes only within one principal growth stage: an
arithmetically greater code indicates a plant at a
later growth stage. Sorting codes into numerical
order therefore allows a listing in order of the
stage of plant development (Meier et al, 2009). In
addition to internodes emergence, one of growth
determination methods is stated explanation of
stem elongation growth in the percentage of final
height of plant species (Hess et al, 1997). Though
three studied cultivars had different final height at
this stage, but proportion height at the end of sub
stage 39 in comparison with sub stage 90 was
relatively stable and about 43% that is a rightindication of this definition in sunflower species.
The pilot study of the Nawab Haji Hassani and
colleagues (2010) on the effects of drought on
forage yield demonstrated that some phenological
traits of millet (late cultivation), was that the
levels of irrigation, plant height, fresh and dry
forage yield had significant differences. Growth
stages 5 and 9 are identified as plant reproduction
stages (Hess et al, 1997) that have begun from
flowering stage and continued with flower
development, fruit and seed ripening and finally
finished with plant dead and dry. These stages
have special importance in farm plants; on theother hand, they dont have any significance in
weedy plants (Cautin and Agusti, 2005). As you
see on the table, Record cultivar growth increased
from the beginning of growth stage 5. So that
Inflorescence development stages completed at
shorter times and finished time period about 5
days in comparison with two other cultivars at this
stage. On the other hand, plant height in this
cultivar is higher than two other cultivars at stage
6 that starts with flowering and finishes with
flowering completion. Also Record cultivar

finished this stage quicker with 1-day difference
with two other cultivars and preserved its own
height variety. Height difference became moreand reached 9 Cm and final speed of stage became
severe at stage 7 when fruit development occurs
and Record cultivar finished this stage 10 days
sooner. Height and its variety became stable
among cultivars at stages 8 and 9. But final speed
of stages occurred 8 to 12 days sooner
respectively, and finally it reached to final crop
sooner than two other cultivars, that is, it isconsidered early ripening of this cultivar. Figures
4 to 8 show growth stages 5 to 9 that exactly
similar to the description of each subsidiary stage
in BBCH table.

Conclusion
As it is showed on the table Record cultivar
elongation was quicker than two other cultivars
that this difference was visible from the end of
stage 1. This variety in the speed of elongation
caused the difference in height average about 8
Cm between Record cultivar and Progress and
Hison 33 cultivars. This matter was seen at end
time of growth stages, so that Record cultivar with
more height reached its own growth end stage at
shorter time (13 days) that was an indication of
early ripening of this cultivar in comparison with
two other cultivars. According to the obtained
results the time of fertilizing, irrigation, and weed
control in Record cultivar that was earlier ripening
should be done in different time rather than other
cultivars. Also this cultivar can be cultured after
wheat harvest and harvested before winter chill.
