遗传分析表明，株高和穗位主要受基因非加性效应支配，环状气生根的基因加性和非加性效应相当，故对根倒伏的抗性应强调非等位基因的互作，亲本之一必须抗根倒才能有望配成抗根倒的杂交组合。

The result showed that with the increasing of density, plant height was increased, stem diameter and ear diameter was decreased, ear was shorten, rare top length、No. of ear nod、ear height was increased;brace root number and total root number was decreased, the rate of root dry weight was increased within farming layers; population dry matter accumulation was increased and plant dry matter accumulation presented the opposite trend; ear linage、kernels per ear、100-kernels weight、double-ear rate、plant yield was decreased, yield was increased and decreased successively.

结果表明：随群体密度的增加植株高度增高、茎粗、穗粗变细、果穗变短，秃尖长度、穗位节数和穗位高度呈现增加的趋势；气生根与总根数减少，耕层根系干重比例增加；群体干物质积累量随密度增加而增加，单株干物质积累量呈相反的趋势；穗行数、穗粒数、百粒重、双穗率、单株产量均随密度的增加而减低，群体产量先增后降。

The rate of dry matter in maize bract and stem sheath transported to seed was the highest.

作物经济产量的高低是由生物产量即干物质积累的多少所决定的，但又受经济系数的制约。

Of or relating to a sessile leaf or bract that completely clasps the stem and is apparently pierced by it.

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.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有"盾状心皮"的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出"囊状心皮"的特点。
