摘　　要：以辣椒雄性不育两用系AB114为试材,采用石蜡切片技术,对不育株系和可育株系花粉母细胞减数分裂过程以及花药和小孢子的发育过程进行了对比观察。结果表明:不育株系花粉母细胞减数分裂行为异常,败育现象从造孢细胞时期以后每个阶段都有发生,绒毡层发育异常是导致小孢子败育的主要原因。The meiosis behavior of pollen mother cell and development of anther and microspore of genetic male sterile （GMS） pepper were studied comparatively by means of paraffin section. The results showed that the meiosis behavior of the sterile line is abnormal. Abortion occurred from multiplication stage of sporogenous cells. Conclusion tapetal abnormalities was the main reason of microspore sterility.
