摘    要:本文报道了安吉小鲵(Hynobiusamjiensis)、中国小鲵(H.chinensis)、东北小鲵(H.leechi)(辽宁桓仁)和极北鲵(Salamandrelakeyserlingi)(吉林白河)的核型。3种小鲵2n=56,染色体按大小和形状分为大、中、小型双臂和小型单臂4组。极北鲵2n=62,染色体按大小和形状可分为大、中、小型3组。对东北小鲵辽宁桓仁与辽宁千山标本核型的显著差异结合分类学问题进行了讨论。对3种小鲵核型进行了比较分析,并讨论了中国的小鲵属核型特点。比较了不同地区极北鲵核型的异同,并将其与小鲵属核型进行了比较。

关 键 词:小鲵,极北鲵,核型

Abstract:The karyotypes of Hynobius amjiensis,H chinensis,H leechii (Huanren Co ,Liaoning) and Sallamandrella keyserlingii (Baihe Co ,Jilin) were investigated Three species of Hynobius had 2n=56 with 4 groups of large,middle,small biarmed chromosomes and uniarmed small chromosomes S keyserlingii had 2n=62 with 3 groups of large,middle and small chromosomes The conspicuous differences of karyotypes between Huanren and Qianshan districts of H leechii were discussed associated with their taxonomical problems The karyotypes of 3 species in Hynobius were compared and analysed,and the characteres of karyotypes of Chinese Hynobius were discussed The karyotypes of different districts of S keyserlingii were compared and the karyotype of S keyserlingii was compared with those of Hynobius
Keywords:Hynobius  Sallamandrella keyserlingii    Karyotypes
