| Abstract: | Pollen abortion in the nuclear male sterile Chinese cabbage wasstudied.The result showed;In the male sterile plant,the development ofmicrospore mother cells was normal,the meiosis proceeded normally toform the tetrads;Microspore abortion occured after the tetrad formation.with the abortion of microspores,the tapetal cells were seen to have ananomaly division,consequently the tapetum became three-or-more-layeredthick,packing almost all the space of anther chambers. |
