摘要
本文研究中华花龟的核型和ＮＯＲｓ，其目的：为花龟属的分类，进化及探索其细胞遗传特性提供资料．方法：以外周血淋巴细胞为材料，以蒸气固定—空气干燥法制备染色体标本，常规方法分析核型．用一步染色法显示ＮＯＲｓ．结果：２ｎ＝５２，ＮＦ＝７６，核型模式为９＋５＋１２，花龟的一对ＮＯＲｓ位于Ａ组Ｎｏ．７长臂．结论：中华花龟的核型和ＮＯＲｓ均具有Ｂａｔａｇｕｉｎａｅ亚科龟类的保守性特点，就ＮＯＲｓ分析。
The paper reported the karyotype and Ag NORs of Ocadia sinensis. Take aim at offer data of taxonomy, evolution and cell genet for Ocadia. This paper describes analysis on karyocytes and Ag NORs in chromosomal specimen of peripheral blood lymphocytes of O.sinensis prepared by the colchicine hypolonic air drying technique, using normal karyotypic analysis. The Ag NORs by a 1 step, simple Ag NOR staining method is revealled. The results indicate that the diploid number of O.sinensis is 2n=52, NF=76, karyotypic formula is 9+5+12. The Ag NORs is appeared of the long arm of 7th pair of chromosomes of group A. This species, like most other members of Bataguinae, possess more strong conservatism. Besides, Ag NORs homology for O.sinensis and Rhinoclemmys were observed.
