摘要
目的：研究南草蜥的核型和Ｇ带带型，从细胞学角度确定南草蜥的分类位置。方法：采用常规空气干燥法制片，质量分数为１０％Ｇｉｅｍｓａ液常规染色，胰酶消化法制作Ｇ带核型。结果：南草蜥染色体数２ｎ＝３８，由１８对常染色体和一对性染色体组成，核型为３８，ＺＷ（ＺＺ），核型中染色体均为近端或端着丝粒类型，各对染色体均有各自的特征性Ｇ带带型。结论：南草蜥是蜥蜴目石龙子——蜥蜴群中的典型物种，是蜥蜴目中较原始的种，但比北草蜥和白条草蜥更进化；核型和Ｇ带带型对物种鉴定和分类具有一定的参考价值。
Objective:To study the karyotype and G banding pattern of Takydromus sexlineatus meridionalis Gunther Methods:making specimen slides by general drying in the air,staining the specimen slides with 10%Giemsa solution,and making the G banding pattern by digesting with trypsin Results:Its karyotpye is 38,ZZ(ZW),and the karyotypeic formula is 2n=16T+22ST; its chromosomes can be divided into 3 groups Every pair of chromosomes have their characteristic G banding pattern Conclusion:It is a typical species of Scincolacertoidae and a primitive species in Saurta,but it is more evolutional than Takydromus septentrinalis Guenther and Takydromus woiteri
