| 摘 要： | 利用扫描电镜和透射电镜分别观察了近江蛏和缢蛏成熟精子的超微形态结构。发现近江蛏精子与缢蛏精子在超微形态结构上差异很大。近江蛏精子为典型的原生型,成熟精子由头部、中段和尾部组成,头部包括顶体和细胞核。近江蛏精子与缢蛏精子顶体均为保龄球状,但近江蛏精子顶体全长比缢蛏短。近江蛏精子细胞核略扁圆形,外缘具8～9个圆弧形凸起；缢蛏精子细胞核则呈圆球状。近江蛏精子中段由线粒体和中心粒复合体构成,线粒体一般5个,个别4～6个；缢蛏线粒体5个或6个。近江蛏精子尾部为细长的鞭毛,轴丝为“9 2”结构,与缢蛏的相同。从近江蛏与缢蛏的精子形态差异看,两者应属于种间差异。

| Abstract: | Sinonovacula rivularis sp.nov.,found in Minjiang Estuary Waters of Fujian Province,was identified as a new species after study,and it belonged to Sinonovacula,Pharellidae,Bivalvia.The outer shape for the shell of S.rivularis sp.nov.was similar to that of S.constricta(Lamarck,1818),and it was likely that S.rivularis sp.nov.and S.constricta had a relatively closer affinity.Because the morphological structure of spermatozoon had the specificity of species,the differences between the species could be shown by s... |
