| 摘 要： | 通过电镜观察，描述了栉孔扇贝精子形成过程的超微结构变化。栉孔扇贝的精子过程可分成为早期，中期和后期３个阶段。（１）早期：细胞核呈团块状，近端中心粒移向精子细胞的后端并嵌在核的凹窝处，在被观察的视野内，可见到大量与精子细胞分离的成熟鞭毛。（２）中期：核由团块状向流线型转变。顶体泡向帽状顶体转变，顶体下间隙开始出现。近端中心粒分化出中心粒卫星体。（３）后期：精子细胞核变成上窄下宽的长柱状，形成帽状顶体

| Abstract: | The ultrastructure of spermiogenesis of Chlamys farreri was observed with EM. The spermiogenesis consists of three stages. (1)Early stage: aproximal centriole inserts the implantation fossa behind the lump nuclear. A large number of flagellums were observed around lump nuclear. (2)Middle stages: the nuclear changes from lump to streamline. Preacrosome vesicle changes shape and become acrosome and subacrosmal space. The centriolar satellite was disintegrated from the proximal centriole. (3)End stages: acrosome and subacrosmal space cover on the top of the barrel-shaped nuclear, the centriole tubes form, and a mature sperm appears. |
