gynoecium n.(pl. -cia ) 【植物;植物學】雌蕊群。

gynophore

In this paper the floral ontogeny and the ovary development of rivina humilis l . were observed . the results showed that ( 1 ) the tepal primordia initiated in 2 / 5 spirals . the abaxial one initiated first , then the adaxial one , finally the lateral two initiated nearly simultaneously . the third one initiated on the position near the first tepal , and there is a gap between itself and the second tepal . ( 2 ) the 4 stamineal primordia initiated in one whorl at the same time . ( 3 ) the carpellary primordium initiated from the abaxial side of flower primordium ; the carpellary primordium grew upwards and towards axis after it was formed , therefore an elliptic orifice was formed at the adaxial position of ovary , which was the remainder of the mouth of ovary before the ovary was fused completely . with the ovary maturing , the orifice was narrowed because of the ovary growth , at last fused completely . the gynoecium is composed of a single carpel . ( 4 ) in the series developmental sections of ovary , the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed 對數珠珊瑚的花器官發生和子房的發育過程進行了觀察.結果表明: ( 1 )數珠珊瑚花被呈2 / 5螺旋狀發生,遠軸側的1枚先發生,其次為近軸側的1枚發生,最后側方的2枚花被幾乎同時發生,第3枚花被在靠近第1枚的位置發生,第2枚和第3枚之間有1個空隙; ( 2 ) 4枚雄蕊是同時發生的; ( 3 )心皮發生于分生組織的遠軸側,心皮原基形成后,向上向軸生長,在子房成熟前在近軸側非正中位形成1個孔,該孔為心皮最終愈合前的殘跡,到子房成熟時,因子房的生長孔被擠壓縮小,在進一步的生長過程中愈合.子房由1枚心皮構成; ( 4 )從子房發育過程的切片看,該植物的胚珠是在子房發生后不久發生的,子房上的圓孔形成時,從近軸側的分生組織發生胚珠原基,由胚珠原基分化出珠被與珠心

Each flower may have one or more carpels borne singly giving an apocarpous gynoecium or fused together giving a syncarpous gynoecium 有的種類植物的雌蕊是由幾個心皮構成的,其中的心皮各自分離稱為離生雌蕊,有的心皮互相聯合稱為合生雌蕊。

A gynoecium with only one carpel is called monocarpellary ; with two or more separate carpel , apocarpous ; and with fused carpels syncarpous 只有一個心皮的雌蕊稱單心皮,具兩個或更多分離的心皮稱離生心皮。

Gynoecium ( pl . gynoecia ) the carpel or carpels of a flower 雌蕊群(雌蕊) :一朵花中由一個或多個心皮組成的結構。

The gynoecium is denoted by the letter g in the floral formula 合在一起的多個心皮稱合生心皮。
