对麻疯树花序、雌花及雄花连续石蜡切片进行观察,结果表明:同一花序不同分枝上花的发育下部枝早于上部枝.同一花序分枝上位于二歧聚伞花序的中央的花发育早期早于两边的花.雌花在发育上经过两性时期,但雄蕊后来停止发育,形成功能上的单性花;雄花的发育则不经过两性时期,即在结构和功能上均为单性花.胚珠原基在发育过程中生长方向发生约90°改变,最终形成倒生胚珠.
Morphological and Anatomical Structure of Flowers of Jatropha curcas
In this paper we conducted an anatomic study on the inflorescence, the female flower and the staminate flower of Jatropha curcas. The results showed that the flower development on the lower branch was earlier than that on the upper branch in the same inflorescence and the terminal flower developed before the two lateral flowers did in the same dichotomous cyme. There was a bisexual period in female flower during developmental period but not in male which is unisexual flowers. The ovule primordium changed its orientation by 90° during the development and finally formed anatropous ovule.
