摘要
以蚕豆为试验材料,利用微核检测技术研究井冈·三环唑和苯甲·咪鲜胺对蚕豆根尖细胞的遗传毒性效应。结果表明:与阴性对照比较,不同浓度的2种药剂处理后,蚕豆细胞微核率和污染指数都有不同程度提高,但是不呈明显的浓度—剂量效应关系;通过回归建模分析可以发现,二次函数模型能更好地描述微核率随药剂浓度的变化趋势。此外,相同浓度下苯甲·咪鲜胺对蚕豆微核率和污染指数影响比井冈·三环唑更大。
Using micronucleus detection technique,the genetic toxicity of Jinggangmycin＆#183;Tricyclazole and Benzophenone＆#183;Prochloraz to root tip cells of V icia faba was explored.The results showed that compared with the negative control,treatment with different concentrations of the two fungicides resulted in different-leveled improvement of micronucleus rates and pollution indexes,but not in a concentration-dose response relationship.Regression modeling analysis revealed that quadratic function model exceled in description of micronucleus rate trends over concentration. In addition,Under the same concentration,the treatment of Benzophenone＆#183;Prochloraz showed higher influence in the micronucleus rate and pollution index than the treatment of Jinggangmycin＆#183;Tricyclazole.
