高温对桑蚕雄蛾附腺发育及不育性的影响

    THE INFLUENCE OF HIGH TEMPERATURE ON THE GROWTH AND DEVELOPMENT OF MALE ACCESSORY GLANDS AND THE STERILITY IN SILKWORM (Bombyx man L. )

    • 摘要: 1.高温(上族后34℃处理)导致附腺畸形;长度缩短;干重减轻.2.高温引起腺体组织构造发生变化.核系统受破坏;核质不均匀;粗面内质网断裂、线粒体被破坏.3.腺细胞中的DNA、RNA含量减轻.4.分泌物中蛋白质及其氨基酸组成改变、含量减少。5.高温处理时间愈长,精子活力愈弱,不受精卵率愈高。

       

      Abstract: 1. At high temperature, (34f33 after mounting) the male accessory glands showed adnormal shapes, shorter length and lighter dry weight. 2. High temperature caused changes in the histological structure, such as damaged nuclear system, nonhomogenous nucleoplasm, broken rough endoplasmic reticulum, damaged mitochondria. 3. The DNA and RNA contents decreased. 4. The compositions of protein and amlno acid in the secretion were changed and (heir contents decreased. 5. The activity of motile sperms varied with the duratJon of the high temperature treatment, the longer the time, the weaker the activity and hegher the percentage of unfertilized eggs.
