摘　　要：研究了不同浓度的精禾草克对鲹鲦红细胞微核及核异常的影响,结果表明:精禾草克能显著诱导鲹鲦红细胞微核及核异常的发生,与对照组相比,差异显著或极显著(P<0.05或P<0.01),并且在一定浓度一定处理时间内,微核率和核异常率与浓度呈正相关.精禾草克具显著的遗传毒性.Effects of Quizalofop-p-ethyl on micronucleus and nuclear anomalies in erythrocytes of Hemiculter leucisculus, were studied in this paper. The results indicate that the micronucleus and abnormal nuclei of the erythrocytes of H. leucisculus could be induced by Quizalofop-p-ethyl with certain exposure periods and concentrations, and it is significantly different in comparison with control group（P〈0.05 or P〈0.01）. At certain range of Quizalofop-p-ethyl concentration, the micronucleus rates show a dosagedependent elevation. All results suggest that Quizalofop-p-ethyl can cause significant genetic damages to the erythrocytes of Hemiculter leucisculus.
