用透射电镜观察了短尾鮠的精原细胞、初级精母细胞、次级精母细胞、精子细胞和精子的形态以及细胞核、拟染色体和线粒体等的结构变化规律.结果表明:精原细胞时期细胞器较丰富,到精子细胞后期,细胞器的形态和数量发生了较大变化;随着精母细胞的发育,核质凝聚程度逐渐增强.短尾鮠的精子具有椭圆的头部和复杂的中片,近侧中心粒和远侧中心粒靠近核的中央,鞭毛呈9+2轴丝结构,并具有由外膜折迭形成的波浪形的结构.表明短尾鮠精子发生中具有某些区别于其它鱼类精子的不同结构.
The morphological changes of spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids and sperm and nucleus, chromosomes and mitochondria were observed by transmission electron microscopy. The results showed that during the period of spermatogonia, the organelles were abundant, and the morphology and number of organelles changed greatly to the late stage of spermatids. With the development of spermatocytes, the aggregation degree of nuclei increased gradually. Short-tailed hamsters have oval heads and a complex middle piece with proximal and distal centrils near the center of the nucleus. The flagellum has a 9 + 2-axis wire structure and has a wavy shape formed by the folding of the adventitia Structure. It shows that the structure of spermophilus macaques is different from that of other fish sperm.
