本文研究了棉红铃虫[Pectinophora gossypiella(Saunders)]辐射不育子代(F_1代)和未处理对照雄虫睾丸和复射精管区有核精子束和无核精子束在数量和形态上的区别。F_1代和对照雄虫睾丸内含有大量无核精子束,同时在复射精管内有正常数量的分散游离的无核精子。同样,F_1代和对照雄虫的睾丸内都含有许多不成熟的有核精子束。可是,对照雄虫的这些精子束成熟后,从睾丸排出,并贮存于复射精管内;而 F_1代雄虫睾丸内成熟的有核精子束显著减少,许多 F_1代雄虫复射精管内没有有核精子束。亲代(P_1)雄虫经辐照后影响子代(F_1)雄虫的精子发生和形成,使大多数有核精子不能下输到复射精管,成为有效的可授精精子。
In this paper, the quantitative and morphological differences between nucleus pulposus and nucleus pulposus in Pectinophora gossypiella (Saunders) male sterile (F_1 generation) and untreated control male testis and doubly sperm cells were studied. F_1 and control male testicles contain a large number of non-nuclear sperm bundles, while in the ejaculatory duct there is a normal amount of free, non-nuclear dispersed sperm. Similarly, F_1 and control male testes contained many immature nucleated sperm bundles. However, when the control sperm bundles mature, they are excreted from the testes and stored in the ejaculatory duct. However, the number of mature nucleated sperm bundles in testis of F 1 males is significantly reduced, and many F 1 males do not have nuclei Sperm beam. The irradiated parental (P_1) males affected the spermatogenesis and formation of the offspring (F_1) male, making most of the nuclear sperm unable to be translocated to the ejaculatory duct, making them effective pheromones.
