本文在超微结构水平上,着重研究了西埔湾黄鳍鲷精子发生和形成过程中各级精细胞形态结构的变化、线粒体和高尔基体等细胞器的演变特点以及精巢内一些体细胞的形态结构与功能。研究结果证实了黄鳍鲷雄性性腺能在半封闭的西埔湾内发育成熟。精子发生和形成可分为原始精原细胞、精原细胞、初级精母细胞、次级精母细胞、精子细胞和精子形成等6个发育阶段。成熟精子由头部、中段和尾部组成,头部近圆形,细胞核呈马蹄形,核内染色质高度浓缩,核上方不具顶体。尾部轴丝为“9×2+2”结构。
This paper focuses on the ultrastructure level, focusing on the changes in spermatogenesis and formation of spermatophyte at all stages in Xipu Bay, the evolution of organelles such as mitochondria and Golgi, and the morphological structure of some somatic cells And function. The results of the study confirmed that the male gonads of the yellow snapper can mature in the semi-closed Xipu Bay. Spermatogenesis and formation can be divided into primitive spermatogonia, spermatogonia, primary spermatocytes, secondary spermatocytes, sperm cells and sperm formation in 6 developmental stages. Mature sperm from the head, middle and tail composition, the head nearly round, the nucleus was horseshoe-shaped, highly concentrated nuclear chromatin, the top of the nucleus is not acrosome. Tail shaft wire for the “9 × 2 +2” structure.
