| 摘 要： | 用透射电镜（TEM）观察了毛蚶精子发生过程中线粒体的行为，结果表明，精原细胞期，胞质中线粒体分布较为分散，数量较少，初级精母细胞期，线粒体较低中分布于细胞的一端，数量较多，次级精母细胞期，线粒体数目开始减少，但体积增大，精细期，线粒体融合成数个大的线粒体球并迁移至细胞核的后端，与此同时，由溶酶体形的顶体囊迁移至细胞核的前端，线粒体主要参与精子中段的形成。

| Abstract: | The mitochondrial behavior of Scapharca subcrenata was investigated by Transmission Electron Microscopy(TEM) method. The result show that, there are little mitochondria in cytoplasm of spermatogonium； at spermatocyte Ⅰ stage， the number of mitochondria increased, located at one pole of spermatocyte Ⅰ ； at spermatocyte Ⅱ stage, the number of mitochondria decreased, but the volume increased; at spermatid stage, mitochondria fused, formed a small number of big volume ones, located at the post part of nucleous, at the same time, the pre－ acrosomal sac formed by lysosomes and moved to the opposite pole of spermatid, and later formed acrosome. Mitochondria mainly take part in the formation of mid－ piece of sperm. |
