摘　　要：从库活性变化、库源调节、内源激素变化动态等多方面综述了前人在玉米子粒败育研究方面的进展 ,尤其对乙烯与玉米子粒败育的关系进行了探讨 ,发现败育子粒在授粉前期子房长度及重量明显低于正常子粒。子粒败育过程 :0～ 8d为败育诱导期 ,8～ 16d为表现衰退期。The present paper reviewed new progress in the studies on maize kernel abortion from source sink mainpulation and regulation, Changes of andogenous hormone levels and so on, and the relationship of ethylene and maize kernel abortion were specially discussed. The results were as follows:the ovary length and weight of the abortive kernels were lower than that of well developed kernels; The caurse of kernel abortion can be divided into two phases:0～8 d was the inducing phase,while 8～16d was the inducing phase, and 8～16d was the obviously degrade phase.It can be concluded that aborted kernels at the ear tip have a close relationship with their low sink strength.
