摘要: 本文对三个不同品种的春小麦的受精过程及其各阶段持续的时间进行了研究,其结果如下:1.授粉后1小时,花粉管破坏一个助细胞将精核释放于卵细胞与极核之间。2.授粉后1.5小时,精核进入卵细胞,精核在卵细胞的细胞质里有不同的取向。授粉后2小时,精核附在卵核的核膜上。3.授粉后2.5小时,精核进入卵细胞核,精核的染色质逐渐松解。授

Abstract: The results are summarized as follows:(1)1 hour after pollination,the pollen tube destroys a synergid andreleases the sperm nuclei between the egg cell and the polar nuclei.(2)1.5 hour after pollination,one sperm nucleus enters the eggcell and takes different orientations in the cytoplasm of the egg
