| 摘 要： | 采用银染及荧光染色技术，对6种鲤科鱼的NORs进行了研究。结果表明：这6种鲤科鱼中瓦氏雅罗鱼、花 、麦穗鱼、白甲鱼具有2个NORs,长春鳊、墨头鱼具有4个NORs。根据实验研究结果对鲤科鱼类NORs多态性及演化等进行了讨论。The NORs were examined in 6 species of Cyprinidae by both silver nitrate and chromomycin A3,which led to the detections of 2 NORs in 4 species(Leuciscus waleckii,Hemibarbus maculates,Pseudorasbora parva,and Varicorhinus simus)and of 4 NORs in 2 species (Parabramis pekinensis,and Garra pingi pingi).Based on our results,the variation and evolution of fish NORs were discussed.
