摘要: 利用光镜和透射电镜对番茄雄性不育突变体95305的小孢子发育进行了细胞学观察。结果表明,小孢子的败育发生在小孢子母细胞时期、四分体时期以及单核小孢子时期。绒毡层细胞行为异常,表现为小孢子母细胞时期提早被破坏解体,或绒毡层细胞多层径向分化,异常肥厚,挤压单核期的小孢子。此外败育方式还有单核中期小孢子无法进行外壁沉积,或小孢子的细胞质被降解成空壳,以及花药畸形,花药上长出许多附属物等异常现象。

Abstract: Comparative observations on microspore development in a male sterile 95305 and fertile plants of L.esculentum were made with light and transmission electron microscopy. The results showed that the microspore abortion occurred at the stage of microspore mother cell, tetrads and uninucleate microspore. The tapetal cells were desolved completely earlier than that of normal male fertile material, or divided into multilayer to press the microspores. Other kinds of microspore abortion such as the failure of exin deposition also were reported. In addition, some anthers were deformed and had pistillody.

Key words: Tomato, Male-sterility, Microspore development
