摘要
本工作对茄子花芽的发生与发育过程进行了初步观察,花芽发育的顺序为花萼、花冠、雄蕊、雌蕊。 花萼和花冠在发育过程中,下部都分别连合形成萼筒和花冠筒,上部分离形成花萼裂片与花冠裂片,彼此相间排列。雄蕊5～7个原基,与花瓣互生,花丝基部与花冠筒贴生。雌蕊,2～3心皮上位子房,发育早期心皮原基分离,后逐渐愈合形成中轴胎座。
Preliminary observations have been carried out about the genesis anddevelopment of flower buds of Solanum melongena 1. cv Longicarpa inthis task. The results show that the sequence of development of flowerbuds is calyx, corolla, stamen and pistil. In the course of development of calyx and corolla, their bottomslinked to form calyx tube and corolla tube, and their tops separated toform calyx lobes and corolla lobes respectively. The calyx lobes andcorolla lobes are arranged alternately with each other. Stamen has fiveto seven alternipetalous primordia. The base of filament sticks on corollatube. Pistil has two to three carpellary superior ovaries. In the earlystage of development, carpellary primordia separated, gradually healed upand formed axile placenta.
