采用模拟人工授精、组织学及电子显微镜观察等方法,研究了青蟹精子塞的形成机制。结果发现,青蟹精子塞为雄性精液和雌性纳精囊开口处的分泌物在短时间内发生剧烈反应的产物,它们在短时间内从液态变为胶状结构,证明了精子塞是雌雄蟹的共同产物。雌雄蟹形成的精子塞的作用是,将精液颗粒、精荚等紧密联系在一起,部分精荚被拉伸破裂;有助于防止后续的雌雄交配,保护或保持精荚的完整及具有营养作用。
Using simulated artificial insemination, histological and electron microscopy methods to study the formation of crab crabs. As a result, it was found that the semen of crab crab was a product of a violent reaction between the secretions of male semen and female seminal vesicles in a short period of time, which changed from a liquid state to a colloidal structure in a short period of time, demonstrating that sperm plugs are male and female crabs Common product. The function of the sperm plug formed by the male and female crabs is that the sperm particles and the fine pods are closely linked together, and part of the sperm pods are stretched and ruptured; it helps to prevent subsequent mating between males and females and protects or maintains the integrity and nourishment of the sperm pods .
