摘 要 ：本文对籽粒败育与乙烯的关系进行了探讨。采用两类不同基因型(果穗顶端败育类型和正常类型)玉米杂交种为材料，对籽粒发育前期乙烯的代谢变化进行了双向比较研究。结果表明：籽粒的乙烯释放量在授粉后的0~8天((0~8DAA)出现高峰。同期败育类型玉米籽粒的乙烯释放量显著高于正常类型；在同一类型中又表现为顶部高于中部。这种乙

Abstract:A comparative study was conducted on the kernel ethylene metabolism during the early period of kernel development with two kinds of genotypes. The main results were as follows: Kernel ethylene releasing peaked during 0~8 days after anthesis (DAA)，and the value of ethylene releasing of the genotype
