    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.

    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

    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.
