摘　　要：该文研究赤链华游蛇的染色体组型与NORs,结果:2n=44(2M+2SM+2ST+10T+26m+ZW),NF=52。No.2染色体有一对随体,No.5为异型性染色体(ZW型);NORs位于No.2的次缢痕区,未见其融合或扩增现象。The karyotype and Ag\|NOR\-s of Sinonatrix annularis have been studied.The results shown the diploid is 2n=44(2M+2SM+2ST+10T+26m+ZW).The nombre fondamental(NF) is 52.There is a satellite on the No.2 chromosome.The No.5 is sex chromosome(ZW type).A pair of NORs was observed on the region of secondry constriction of the No.2 chromosome.There is no evidence of fusin or increase of NORs in Sinonatrix annularis.
