摘要: 本文研究七子花的减数分裂及小孢子形成过程。七子花小孢子母细胞减数分裂为同时型,从小孢子母细胞后期到游离四分体产生为止,其周围均包围着一层胼胝质体,七子花的四分体主要为四面体型,单核小孢子呈三角形,花药壁的发育为双子叶型。

关键词: 七子花, 减数分裂, 小孢子

Abstract: The meiosis and the formation of microsporogenesis of Heptacodium miconioides was studied. The meiosis of microspore mother cells is of simultaneous type. The arrangement of microspores in tetrad is tetrahedral and sometimes decussate or isobilateral. The development of anther walls belongs to dicotyledonous type.

Key words: Heptacodium miconioides, meiosis, microspore
