With high quality cotton Yuma No. 1 (Gossipier Hirsutum. L) as the testing material, different combinations of population density, fertilizer and DPC chemical spraying were adopted to study the dynamic changes of endogenous hormone contents, the vigor of source-sink and the nutrient transportations from boll walls to lint cotton as well as fiber qualities on different positions.

本论文以高品质棉花渝棉一号为材料，通过密度、肥料和DPC化控等不同水平的调节，从不同部位棉铃的源库活性、内源激素、铃壳中养分运转、棉花品质等方面着手研究高品质棉花渝棉一号不同部位的棉铃发育及其调节机理。

The results show:(1) After soybean seed is treated with seed coating, The length of lateral root anlage Initiating area obviously increases in contrast with control (seed which is not coated with agent is regarded as control; shortened form is CK).The order is from greatness to smallness in turn as follow: HK＞ND＞CK.(2) Initiating progress of lateral root anlage is quickened when seed is treated with seed coating. General trend is as follow: HK＞ND＞CK. By variance analysis, treatment and control has obvious difference.(3) Initating status of lateral root anlage is definite related with contents of endogenous hormone. Occurring of lateral root is as the result of some endogenous hormone corresponded and playing manysided role, especially IAA plays important role in the cause of inducing to occurring of lateral root anlage.(4) The use of seed coating may elevate the number of lateral root anlage occurring and shorten the time of lateral root anlage occurring, especially the effect of Chemical control seed coating is better.

结果表明：(1)种衣剂包衣后，侧根原基发生区长度明显比对照(不包衣的种子为对照，用CK表示)增加，从大到小依次为：HK＞ND＞CK；(2)种衣剂处理加快了侧根原基的发生进程，总的趋势是HK＞ND＞CK，经F检验表明，处理和对照差异极显著；(3)侧根原基的发生状况与侧根原基发生区内源激素的含量有一定的关系，侧根的发生是几种植物内源激素相互协调、综合作用的结果，其中生长素类物质在诱导侧根原基的发生过程中起主导作用；(4)应用种衣剂可以提高侧根原基发生的数量，缩短侧根原基的发生时间，其中以化控种衣剂效果最好。

Comparison of different types of stem cutting in rooting induced and analysis the cDNA clones which may be associated with the occurrence of adventitious roots of P.euphratica,the model of ARF were initial establishment of exogenous IBA controlling endogenous IAA occurred threshold and equilibrium,that is,exogenous IBA receiving by receptor of stem cutting,and transfer into the cells,then turn into active IAA by the effects of the POD enzyme.

通过对胡杨3个不定根发生调控培养体系的比较和与胡杨不定根发生可能相关的差异基因的克隆分析，初步建立IBA调控胡杨不定根发生的内源IAA阈值和激素间平衡的模型，即外源IBA通过插穗受体接收，转入细胞内并在POD酶作用下转化成具有活性的IAA，当IAA的水甲在促根的阈值内并保持相对平稳时，则有利于生根；当IAA的浓度增高超过阈值且不稳定时，则抑制不定根的发生。

In this study,relationship between internal hormones and Barren Ear Tip was studied.Results showed that during faster filling period of maize grain there were high content of GA,and mid-content of IAA and CTK,and low content of ABA.
