摘 要 ：本文主要研究了中国的四种松干蚧:海松干蚧M.koraiensis;樟子松干蚧M.dahuriensis;日本松干蚧M.matsumurae;马尾松干蚧M.massonianae的精子超微结构。研究表明,不同种松干蚧在精子超微结构上具有明显的差异,主要表现在精子核区与非核区微管的排列方式、微管的数量、微管列所跨的角度以及精子、精子束的长、直径等方面。

Abstract:The study reveals that four species (M. matsumurae, M.massonianae, M. koraiensis, M. dahuriensis) have obvious difference in their ultrastructure of sperms.The main difference appeared in the quantity of microtubules, their arrangging patterns and the angle of the microtubular row has been discovered.The key to four species is as follows:1.The microtubules are arranged in whorled radii patterns in the non-nuclear region……2The microtubules are arranged in spirale patterns in the non-nuclear region……32.The angle of microtubules row in non-nuclear region is 170°—190°……M. massonianaeThe angle of microtubules row in non-nuclear region is 30°—50°……M. koraiensis3. In the nuclear region, the microtubules are arranged in whorled radii patterns, the angle of microtubular row is 40°—60°……M. matsumuraeIn the nuclear region, the microtubules are arranged in whorled radii patterns, the angle of microtubular row is 90°—160°……M. dahuriensis
