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。
