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。

摘  要:
Using micronucleus detection technique,the genetic toxicity of Jinggangmycin·Tricyclazole and Benzophenone·Prochloraz to root tip cells of Vicia 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·Prochloraz showed higher influence in the micronucleus rate and pollution index than the treatment of Jinggangmycin·Tricyclazole.
