摘　　要：[目的]探讨皖西白鹅产蛋期卵巢的组织学结构。[方法]应用光镜和透射电镜技术,观察皖西白鹅产蛋期卵巢形态学结构。[结果]皖西白鹅卵巢表面被覆生殖上皮,下方是白膜,其实质由皮质和髓质组成。皮质内含有不同发育阶段的卵泡和萎缩卵泡,大卵泡突出了卵巢表面,卵泡无卵泡腔,也无卵泡液,排卵后不形成黄体。电镜下,卵泡颗粒细胞胞质中有线粒体、内质网、脂滴、高尔基复合体等丰富的细胞器,并且这些细胞器随着卵泡的发育而逐渐增多。卵巢基质中有卵泡外膜细胞、间质细胞和空泡细胞3种细胞,前2种细胞胞质中有丰富的内质网,而空泡细胞胞质中脂滴较多。[结论]阐明了皖西白鹅产蛋期卵巢的显微结构与超微结构。[Objective] The research aimed to discuss the histologieal structure of tuba uterine of Wanxi white geese during laying, [Method] Morphological structure of tuba uterine of Wanxi white geese during laying were observed under microscope and transmission electron microscope, [Result] The surface of the ovaries was covered germinal epithelium, white tunica was under germinal epithelium, the ovary was made up of cortex and medulla. All kinds of developed follicle and atrophic follicles were found in cortex. The big follicles were presented on the surface of ovary and they had no follicle cavity and follicular fluid. Under the transmission electron microscope, the granular cell was contained abundant organelles in the cytoplasm, such as mitochondrion, endoplasmic reticulum, lipid droplets, Golgi complex, microfilament and microtubule and so on, but these organelles were increasing along with follicle growth. There were 3 cells in stroma of ovary, and that was theca folliculi cell, interstitial cell and vacuolar cell, The theea folliculi cell and interstitial cell possessed abundant endoplasmic reticulums, but vacuolar cell possessed many lipid droplets. [Conclusion] Microstructure and uhrastructure of tuba uterine of Wanxi white geese during laying were illustrated.
