摘　　要：目的以蚕豆根尖为供试材料,以不同浓度的Hg^(2+)为受检物质,探讨Hg^(2+)对蚕豆根尖细胞的微核效应。方法实验分析与统计分析。结果Hg^(2+)能诱发较高的微核率,在一定浓度范围内,其微核率随Hg^(2+)处理浓度的升高而增加,但高于一定浓度后,微核率不再上升,反而有下降的趋势。结论运用徽核技术可以检测重金属环境污染物。Aim To study the experiments of the effects on the micronucleus in the root ceils of Vici faba under different concentrations of Hg^2＋. Methods By means of experimenting and analyzing the related data for research. Results Hg^2＋ can induce micronucleus. Within certain range of concentration, MCNF was found to increase systematically with Hg^2＋. Conclusion After the metal concentration reached a high level, the MCNF decreased. Conclusion The MCN test technology can be used to monitor environmental pollution of the heavy metal.
