| 摘 要： | 以我国云南省嵩明海菜花为试材,研究其体细胞染色体数目和核型(2n=2x=22=12m+8sm+2st)。结果表明:嵩明海菜花核型类型为"2B"型,与海菜花属的核型非常相近,这为进一步研究水鳖科海菜花属的系统演化提供了重要的细胞学资料,为海菜花的1个新变种提供细胞学依据。

| Abstract: | Taking Ottelia acuminata var.songmingensis Z.T.Jiang which grows in Yunnan,China as the material.The chromosome number and karyotype(2n=2x=22=12m+8sm+2st) were studied.The results showed that the karyotype belongs of Ottelia acuminata var.songmingensis to ’2B’ and was very similar to that of the Ottelia.This was for further study of the water turtle evolution of the genus Kehai Ottelia acuminata provides important cytological data for the sea to provide a new variety of cauliflower cytological basis. |
