Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

The morphogenesis of floral organs in both srg mutant and wild-type rice Dular (Oryza sativa L.) was observed using the scanning electron microscope. The results showed that the floral primordia were differentiated under irregular pattern in srg mutant. After regular formation of lemma and palea primordia, the floral primordium of srg formed lodicule primordia inner to both lemma and palea, followed by the formation of stamens and carpel.

雄花发育过程中雄蕊原基不断分化而雌蕊原基则退化，成熟的雄花中无雌蕊原基痕迹；雌花发育过程中雌蕊原基不断分化，雄蕊的发育停止但不退化，成熟的雌花中仍可见到发育中途停止的雄蕊。

The floral primordium is initially circular, along with the edge of which slight concaves occur. The outmost whorl of tepal primordia arises as a result of apical meristem division and the floral primordium then is in the shape of triangle. Two further whorls of tepal primordia arise in spiral acropetal sequence and are alternately arranged. When the innermost whorl of tepal primordia is at the late developmental stage, the foremost stamen primordia arise almost simultaneously in spiral acropetal succession and all of the stamen primordia are ultimately arranged in a triangle-cone form. Late in stamen primordium development, carpel primordia arise as same as the young stamen primordia and grow laterally. Grooves are present on the adaxial side of each carpel and develop into ventral sutures gradually closing up.

The reproductive development process of birch was described as follows: Male inflorescences extended from apical bud in early June. In later June, stamen primodium was differentiated in the bract of male inflorescence and the differentiation of bract was generated in female inflorescence. During July, anther layers and archesporial cell were differentiated in anther, then archesporial cell developed into mother microspore cell. Pistil primodium came into being at the same time. In early part of August the meiosis of mother microspore cell started. In later August, mono-nucleus microspore was formed. After September, both male inflorescence and female inflorescence were dormant.

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。
