| 摘 要： | 2003年7月~2005年6月,从嘉陵江收集雌性华鲮性腺材料,通过组织学方法观察其卵子发育的特征。华鲮的卵子发生经过卵原细胞、核酸积累、皮层小泡形成、卵黄积累、成熟卵、退化卵几个时相。卵母细胞核酸时相初期,染色质明显向核膜内侧边缘聚集是卵母细胞早期发育的重要特点。

| Abstract: | From July 2003 to June 2005,ovarian tissues of sexually matured Sinilabeo rendahli were gathered from Jailing River.The dynamics of oocyte development and related sequential cytological events were studied.The characteristics of the oogonium and the oocyte during the first meiotic prophase were described by histology technic.The present study indicates that oogenesis in Sinilabeo rendahli can be defined 5 oocyte stages of ovarian development(i.e.,oogounium stage, nucleic acid accumulating oocyte stage,cortical alveoli oocyte stage,yolk vesicle oocyte stage,full yolk granules stage,mature ovum stage and degeneration stage).The important characteristic of oocyte development in Sinilabeo rendahli is much chromatin assembling at the inner nuclear membrane in early nucleic acid accumulating oocyte stage. |
