%X Male sterile line 337S of wheat (Triticum aestivum) was sensitive both to short day-length and low temperature and to long day-length and high temperature.The shape and abortion process of anther and microspores in 337S were investigated in this thesis.The results obtained were summarized as follows:the anthers of 337S were anormaly short and small,and the filaments were so short that the anthers stretched difficultly.The disorder of the middle layer and the disorganization of mesospore ahead of time were the main reason of abortion for 337S.The MI of meiosis was the main stage of microspores degenerating of 337S in short day-length and low temperature.Long day-length and high temperature that occurred during pollen mother cells stage.
