雄蕊群的形态学,花被(花被片),和花序通常用来划分属和族。
花朵发育阶段可分成出芽期、雄蕊期、雌蕊期、果实期与种子期。
雄蕊群着生在联合的花冠上,刚刚在五个交替排列的花萼和花瓣下面。
花盘在雄蕊群内,分泌蜜汁,圆柱形成或者桶形或垫状或杯状。
花瓣5或无,离生或贴生到雄蕊群的基部,旋转覆瓦状排列。
1·Flower: There are perianth, androecium and gynoecia on receptacle.
在花托上着生花被片、雄蕊群和雌蕊。
2·The stamen initiated in non-direction, and when the androecium has more stamens, the inner initiated first, then the outer.
商陆属的雄蕊发生没有特定的顺序和方向,多雄蕊时内轮雄蕊先发生。
3·The present status and prospect of studies on specific genes for development of androecium, pistil and petals of higher plants are reviewed in this paper.
阐述了近年来有关植物花器官包括花瓣、雄蕊和雌蕊发育的特异性基因研究的现状与展望。
4·The results were as follow:complete flower, corymb inflorescens, imferior ovary, rotate corolla, androecium with 16~30 stamens, compound pistil with 5~6 stigmas;
结果表明:香梨为完全花,伞房花序,花冠轮生辐射对称,雄蕊16~ 30枚,柱头多为5枚,极少数为6枚。
