摘　　要：采用常规骨髓细胞制片法,对黑龙江省产黑龙江草蜥和白条草蜥的染色体组型进行分析。结果表明,两种草蜥二倍体染色体的数目均是38,由18对常染色体和1对性染色体组成。常染色体中17对为端部着丝点染色体,1对为点状染色体;性染色体为ZW型,从核型特征看来,二者都为蜥蜴目较原始的类型。The karyotypes of Takydromus amurensis and T. wolteri from Heilongjiang Province were examined using medulla cells and the colchicine-hypotonic air-dry technique. The results showed that the number of diploid chromosomes in the two species was 38 and were composed of 18 pairs of euchromosomes and a pair of sex chromosome, including 17 pairs of telocentric chromosomes and a pair of spot chromosomes. The sex chromosome was of the type ZW. According to karyotypic characteristics, they are all primitive species within Lacertiformes.
