摘要
以蟋蟀科的北京油葫芦Teleogryllusmitratrus(Burmeister)为材料 ,对其卵子发生的卵黄物质形成过程的超微结构进行了观察。根据电镜观察结果分析 ,北京油葫芦卵黄构成有卵母细胞内部物质与外部物质参与。卵黄发生初期 ,主要以卵母细胞自身合成为主 ,随着卵母细胞发育的进行 ,有外源物质介入卵黄合成之中。它包括两部分物质来源 :一部分是由血淋巴通过滤泡细胞间隙向卵母细胞提供合成卵黄物质 ;另一部分则由滤泡细胞通过指状微绒毛以多泡小体和多片小体的形式向卵母细胞提供合成卵黄的物质。
The vitelline material formation of Teleogryllus mitratus during oogenesis was observed by electron microscopy. The materials of T. mitratus vitelline formation are from inside and outside of oocyte. At early period of vitelline formation involves autosynthesis of the oocyte. With oocyte development, exogenous materials from two sources take part in vitelline synthesis. One is blood lymph that offers some useful materials for the oocyte to synthesize vitelline material directly through follicle cell gaps; another is follicle cells that produce and transmit some multilaminar bodies and multivesialar bodies for the oocyte to support vitellogenesis by the finger like microvilli.
