| Abstract: | In this paper, the karyotypes and Ag-NORs of Pyxidea mouhtii and Cyclemys dentata from China were studies. It was found that the 2n = 52, the karyotypic formula is 9 5 12 in this two species. But P. mouhtii has 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 C. dentata. The cytotaxonomical value of the features of karyotypic structure and the positinal differentiation of NORs between this two spepies is preliminarily discussed. |
