另外,探讨了雌蕊或雄蕊败育的生理意义,在长期的进化中,败育的雌蕊或雄蕊"废物"重新被利用,为同一花中迅速发育的雌蕊或雄蕊提供能量和物质的需求。

By comparing and analyzing the dynamic changes of carbonitride in the floral sex determination of litchi we found that: higher C/N and lower amino acid content are beneficial to androecium differentiation; in contrast, lower C/N and higher amino acid content are adequate for gynoecium differentiation; the amino acid content in androecium is only half of that in gynoecium.

荔枝花性决定中碳氮化合物的动态变化的研究结果发现:C/N较大有利于雄蕊分化,反之则有利于雌蕊分化;氨基酸含量较高有利于雌蕊分化,雄蕊的氨基酸含量仅为雌蕊的一半;脯氨酸与花粉育性存在着密切相关关系。

By comparing and analyzing the dynamic changes of carbonitride in during the floral sex determination litchi,it was found that higher C/N and lower amino acid content were beneficial to androecium differentiation; conversely, lower C/N and higher amino acid content were adequate for gynoecium differentiation; the amino acid content in androecium was only half of that in gynoecium; proline was associated with pollen developmental capacity.

比较分析了荔枝花性决定中碳氮化合物的动态变化,结果发现:C/N较大有利于雄蕊分化,反之则有利于雌蕊分化;氨基酸含量较高有利于雌蕊分化,雄蕊的氨基酸含量仅为雌蕊的一半;脯氨酸与花粉育性存在着密切相关关系。

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。

About 2/3 of adaxial angle of nutlets affixed to gynobase; gynobase longer than nutlets

附着到雌蕊基的大约小坚果的正面的有棱的2/3;雌蕊基长于小坚果 25 Lappula ramulosa 多枝鹤虱

Entire adaxial angle of nutlets affixed to gynobase; gynobase shorter than nutlets.

附着到雌蕊基的小坚果的全缘的正面的有棱;雌蕊基短于小坚果。

The developmental process of W. delavayi indicated that the syncarpous and uniloculate gynoecium was in fact bicarpellate, which consisted of a fertile carpel and a sterile one. It was pseudomonomerous.

根据对雌蕊群的发生和发育过程观察,该种的子房是由一个近轴面的可育心皮和一个远轴面的不育心皮融合而成的单室子房,为假单心皮雌蕊

Differ with answer fruit, hip and aggregate achene achene are become by a beautiful ovarian development, in this kind of floral the flower often has from unripe carpel gynoecium, every gynoecium becomes a relatively independent fructification from development each, form the aggregate achene achene that gathers on a thalamus or hip finally.

与复果不同,蔷薇果和聚合瘦果是由一朵花的子房发育而成,在此类植物的花经常有离生心皮雌蕊,每枚雌蕊各自发育成一个相对独立的果实,最终形成聚集在一个花托上的聚合瘦果或蔷薇果。

Pistil without a gynophore.

雌蕊没有一雌蕊柄。

During the development of process of male flower,the stamen differentiatedconstantly,but the pistillate primordium degenerated and there was noremain of pistillate primordium in mature male flowers.During thedevelopment process of female flower,the pistillate primordiumdifferentiated constantly,the development of stamen stopped but didn′tdegenerated.

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。
