Observation on The Precess of Fertilization of Haliotis discus hannai With Transmission Electron Microscope

摘要: 本文用透射电镜观察了皱纹盘鲍的受精过程。鲍卵子的胶膜使精子活化，并诱发了顶体反应，卵黄膜使顶体反应达到高潮。精子入卵后，卵发生皮层反应并形成受精膜开减数分裂。此外，还观察到鲍的多精入卵现象。

Abstract: This thesis studied the process of fertilization of the abalone (Haliotis discus hannai) with transmission electron microscope (TEM).The jelly coat of abalone egg activated spermatozoa and induced acrosome reaction.The vitelline membrane promoted the acrosome reaction reach the climax.After the sperm entered the egg,the egg cortical reaction took place and the fertilization membrane was formed.Afterwards,the eggs meiosis began.Besides,we found polyspermy of the abalone.
