精子器

蕨类植物桂皮紫萁颈卵器和精子器形态和发育的研究

Study on the morphology and development of the archegonium and antheridium of the fern Osmunda cinnamomea

接种后80d左右开始有性器官出现，精子器的出现较颈卵器早10d左右。

The sex organs were formed in 80 days after inoculation , and antheridia appeared about 10 days earlier than archegonia .

培养80～100d后原叶体成熟，其精子器呈球形，颈卵器为高等蕨类植物典型类型。

The prothallus matured in 80 - 100 days after inoculum . The antheridia is globular . The archegonia is of the type common in the high ferns .

原叶体无毛状体，中脉厚，精子器和颈卵器较大；

The prothallium has no trichome but thick midvein , large antherid and archegonium . However , O.

介绍了近年来蕨类植物游动精子运动器和细胞骨架的研究进展。

The Studies of the Locomotory Apparatus and Cytoskeleton in the Spermatozoid of Ferns ;

结论：Uu在精液中感染直接吸附在精子特定部位，产生精子功能性和器质性损伤，干扰受精。

Conclusions : It showed the damage of function and qualities of sperm could be caused by Uu infection and interfered insemination .

电镜观察证明814可引起精子结构严重破坏，主要损害精子的重要细胞器顶体和线粒体。

Electron microscopic observation proved that '814 ' can cause seve-re damage to the structure of spermatozoa . The damages occurred mainly in the acrosome and mitochondria , the important organelles of the sperm .
