摘要
家蚕人工授精已是较为成熟的技术 ,而家蚕生殖细胞的冷冻保存在特定基因的长期保存等方面具有重要意义。目前评价精子冷存效果的标准主要是依据精子的数量、密度、活动能力、畸形率、顶体完整率等 ,但这些指标并不能准确反映精子的受精能力。而精液当中各种酶活力的变化确切反映了精子的受精能力 ,因而精子酶学研究在评定冷冻精液品质、顶体完整率以及受精过程中的调控等方面具有很好的应用前景。
Artificial insemination of silkworm have been succeed in research, and the cryopreservation of its germ cell have important significance in long-term conservation of the given gene. At present we evaluate the effect of freeze sperm by its quantity,density,motility, abnormal sperm percentage, intact-acrosome ratio and so on. But these index can not exactly reflect sperm fecundation. Yet the change of enzyme content in the sperm can reflect its fecundation. And research of enzyme in the sperm have good foreground in the reflection of the quality of the freeze sperm, intact-acrosome ratio and the control of change of fecundation.
