雌蕊群 Gynoecium

(重定向自Pistil)

雌蕊群,或雌花器英语:Gynoecium),为被子植物花中的心皮的总称。传统上把较典型形态的花的花部中,由子房、花柱、柱头等部位构成者称为雌蕊(pistil),但在一朵花为多心皮、离生的状态下,雌蕊一词的概念便易生混淆,故现在植物系统学上常采用较为精准的雌蕊群

一朵花中的心皮数目可能单一(单一心皮)、或二个以上合生或离生。 单一心皮的例子如豆科植物,成熟后发育为豆荚(荚果)。 具多数离生心皮的例子如木兰科(白玉兰)、八角茴香科(八角)、某些蔷薇科(玫瑰)的植物。 具多数合生心皮的种类,其心皮愈合成雌蕊,概分为柱头、花柱、子房等部。例如瓜类(瓜科),其子房或果实横剖开可见到其切面由三个部份合生而成。

Gynoecium 雌蕊群

Gynoecium (from Ancient Greek γυνή, gyne, meaning woman, and οἶκος, oikos, meaning house) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of (one or more) pistils in a flower and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells.
