除了对卵母细胞起一定的保护作用外，滤泡细胞在卵黄发生中也起着重要作用，即可合成部分卵黄物质供给卵母细胞，而且还可通过滤泡开放为外源性卵黄进入提供通道 - Studies on spermatogenesis and oogenesis in palaemon modestus jiang ye - qin ( chemistry department , huzhou teachers coliege , huzhou 313000 ) palaemon modestus belongs to genus palaemon , family palaemonidae , caridea , natantia , decapoda , class crustacean . lt is a kind of freshwater prawn across china and especially abounds in the taihu lake which is regarded as one of the " three delicacies " of the taiha lake . as for the researches on palaemon modestus , v / e can only refer to spermatogenesis of freshwater shrimp exopalaemon modestus ^ ruang hai - xia et al , 2001 ) , studies on reproductive biology of exopalaemon modestus l . the structure and development of the male reproductive system ( huang hai - xia et al , 1999 ) and studies on freshwater prawn in the taihu lake ( yan sheng - liang , 1999 ) . on the bases of their researches and with the help of tem , i have made further researches on sperm ultrastructure , spermatogenesis , oogenesis and mature oocyte ultrastructure in palaemon modestus
秀丽白虾palaemonmodestus属甲壳纲crustacea十足目decapoda游泳亚目natantia真虾部caridae长臂虾科palaemonidae长臂虾属palaemon ，是我国南北均产的淡水虾，其中太湖产量尤其大，与太湖银鱼、鲚鱼并称“太湖三宝” 。有关秀丽白虾的研究仅见秀丽白虾雄性生殖系统的研究(黄海霞等， 1999 ) 、秀丽白虾精子发生的研究(黄海霞等， 2001 ) 。本人在前人工作的基础上，利用透射电镜技术( tem )进一步研究了秀丽白虾精子的形态、结构及精子的发生过程，同时还研究了秀丽白虾卵的发育过程，从卵原细胞到卵黄发生前的卵母细胞、卵黄发生的卵母细胞及成熟卵细胞，各期卵细胞的形态结构特点及各部分结构的变化情况。
