摘要: 本文分析了锯缘摄龟和齿缘摄龟的核型与Ag-NORs,结果:2FKn均为52,核型模式9+5+12。但锯缘摄龟AN=78, 其NOR位于A组No.4的长臂上,而齿缘摄龟AN=76,NOR位于A组的No.7的长臂。作者对这两种摄龟核型的结构特点和NOR位置差异的细胞分类学意义进行了讨论。G[2]G[-2]
Abstract:In this paper, the karyotypes and Ag-NORs of FKPyxidea mouhtiiand FKCyclemys dentatafrom China were studies. It was found that the 2FKn=52, the karyotypic formula is 9+5+12 in this two species. But FKP. mouhtiihas AN=78, its NORs located on the No.4 q of group A, while AN=76, NORs located on No.7 q of group A in FKC. dentata. The cytotaxonomical value of the features of karyotypic structure and the positinal differentiation of NORs between this two spepies is preliminarily discussed.
