中国龙虾卵子发生及卵巢发育的组织学研究

Histological studies on the oogenesis and the ovarian development in Panulirus stimpsoni

采用组织学方法研究了中国龙虾(Panulirus stimpsoni)的卵子发生、卵巢结构和发育。根据卵细胞的大小、形状、核仁的形态及数目、卵黄颗粒的积累情况、卵母细胞与滤泡细胞的关系等,可将卵子的发生分为卵原细胞、卵黄发生前卵母细胞、卵黄发生卵母细胞和成熟卵母细胞等四个时期;卵巢壁由结缔组织外膜和内生殖上皮构成,生殖上皮分化产生卵原细胞和滤泡细胞;卵巢的结构单位是卵母细胞发育区。根据卵巢的体积、颜色和主体卵细胞的类型等,可将中国龙虾的卵巢发育分为形成期、发育期、将成熟期、成熟期和恢复期共五期。

The oogenesis, the histological structure and development of the ovary in Panulirus stirnpsoni were studied. According to the size and shape of oocyte, the morphology and amount of nuclelus, the growth of yolk and the relationship between oocyte, follicle cell, and oogenesis can be divided into three stages as follows, oogonium, previtellogenic oocyte, vitellogenic oocyte and mature oocyte. The ovary wall is composed of connective tissue and germinal epithelium which will produce oogonium and follicle cell. The oocyte developmental area is the structure unit of ovary. The ovarial development cycle can be divided into five stages according to the bulk, color of ovary and the type of main oocytes： form stage, growth stage, prematuration stage, maturation stage and truce stage.
