摘要
铜鱼的卵巢分为六个卵细胞发育时相,卵子的超微结构表明核仁由纤丝和颗粒两区组成。有核仁外排现象;卵黄颗粒有卵黄泡和卵黄球两种类型,卵黄泡结构复杂,卵黄球有Ⅰ型、Ⅱ型两种,线粒体、内质网和高尔基体与卵黄颗粒的形成有关,卵膜是由卵母细胞代谢产物形成的。
The six phases of oogenesis in the ovary of Coreius heterodon are studied. The ultrastructure of oocyte shows that the nuclealus is composed of nucleolar fibrous region and nucleolar graunlar region and the nucleolus going out is found; there are yolk vesicles and yolk globules in yolk granules and the structure of yolk vesicles is complex and there are two types Ⅰ and Ⅱ. Yolk globules and mitochondria, endoplasmic reticulum and golgi apparatie are related to the formation of yolk granules; egg membance is primary chorion due to the origin of ooeyte.
