Abstract

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
