摘　　要：应用ＤＮＡ复性动力学方法，测定和比较了东北产２种４亚种蝮蛇基因组的中度重复ＤＮＡ序列的百分含量．在黑眉蝮中，蛇岛产群体与千山产群体的中度重复ＤＮＡ含量比黑眉蝮模式亚种更类似，支持了将前二者划分为同一亚种的观点；在白眉蝮中，白眉蝮乌苏里亚种体色为黑和黄的中度重复ＤＮＡ含量非常相似，说明二者的亲缘关系很接近．The moderate repeated sequence component of DNA of several Agkistrodon species (A.saxatilis, A. shedaoensis, A.ussuriensis and A.blomhoffii brevicaudus) from Northeast of China was compared by means of reassociation kinetics of DNA. The results showed that the component of moderate repeated DNA between black and yellow agkistrodon (A. ussuriensis) was very similar, and they were classfied as the same subspecies. The component of moderate repeated DNA of the two populations from Shedao and Qianshan was also extremely similar, but that among Agkistrodon saxatilis and other species was different.
