| Abstract: | To observe crayfish Procambarus clarkii zygote structure.Fixed crayfish fertilized eggs were cut into sections by freezing,H.E staining,and photographs were taken.Crayfish Procambarus clarkii zygote belongs to mesolecithal eggs,and cytoplasm were pushed aside lied in the superficial part of the egg.There was a center zone of dense yolk substance in the zygote,and fingerlike yolk column were given off from the center zone,and varying size yolk granules filled in the yolk column.Crayfish fertilized egg structure can be observed by freezing section. |
