【摘要】 利用活体观察,氨银染色和蛋白银染色的方法,对采自松花江的4种广布种纤毛虫:贻贝棘尾虫Stylonychia mytilus (Müller, 1773) Ehrenberg, 1830、鬃异源棘尾虫Tetmemena pustulata (Müller, 1786) Eigner,1999、尾草履虫Paramecium caudatum (Ehret, 1963)和刚毛榴弹虫Coleps hirtus的形态学进行研究。依据新采集种群,对4个种活体形态和纤毛图式特征,以及鬃异源棘尾虫的发生学特征进行补足性描述。研究对贻贝棘尾虫做了重要重描述,可清晰观察到该种蛋白银染后6列背触毛的排列特征、左右缘棘毛数的具体统计,结果发现,贻贝棘尾虫哈尔滨种群与前人报道的种群相比,形态特征基本吻合,区别在于前者小膜数目多于后者。鬃异源棘尾虫哈尔滨种群与漠河种群相比,形态和纤毛图式方面十分相似,发生模式基本一致,细微区别在于前者左右缘棘毛数目普遍多于后者,前者虫体大小波动范围较小,小核数目多于后者。尾草履虫哈尔滨种群与其青岛种群相比,二者显著差异在于收集管数目前者比后者少。本文榴弹虫与前人报道的刚毛榴弹虫种群相比,盔板带的数目、排列方式、窗口类型等形态学基本一致,细微区别在于本文报道种群体型普遍较前人报道种群略大。更多还原

【Abstract】 The morphology of four widely distributed ciliates(Stylonychia mytilus, Tetmemena pustulata, Paramecium caudatum, Coleps hirtus) from Songhua River were studied using living observation and silver staining methods to complementally descript the living and ciliary pattern characters of Harbin populations of these four species including the arrangement of six rows of dorsal kineties after protargol impregnation and the specific statistics of the numbers of left and right marginal rows of S. mytilus. The results showed that the morphological features of Harbin population S.mytilus were basically consistent with previous reports, except that small membranes of Harbin population were more than previous populations. Compared with the Mohe population, the Harbin population T. pustulata were similar in morphology, infraciliature and the occurrence pattern, and had slightly higher in the number of left and right marginal and more micronuleus. Compared with the Qingdao populations of P. caudatum, Harbin population had significantly less collecting canals. Compared with previous populations, Harbin population of C. hirtus had slightly larger body size.更多还原
