摘 要:Morphology of the cortical reaction in the eggs of Penaeus penicillatus was studied with the light microscopy,scanning electron microscopy and transmission electron microscopy. The cortical reaction is divided into four stages. These stages are unreacted stages, early stages, corona stages and dissipation stage. The cortical rods were released and formed a jelly coating around the surface of the egg. The jelly coating remained until the first cleavage had finished. In the end, the hatching membrane appeared around the egg. It is believed that these cortical reaction are responsible for the prevention of polyspermy by both a chemical and physical block and that also may establish a microenvironment inside a touch chorionic membrane for the developing embryo.Morphology of the cortical reaction in the eggs of Penaeus penicillatus was studied with the light microscopy,scanning electron microscopy and transmission electron microscopy.
