【摘要】 采用植物遗传监测系统,研究了新型杀虫剂吡虫啉和抑食肼对大蒜及蚕豆根尖微核率的影响。结果表明,两种植物根尖微核试验测得的微核千分率与阴性对照组相比均无显著性差异(P>0.05),而与阳性对照组相比却有极显著性差异(P<0.01),提示吡虫啉和抑食肼对大蒜及蚕豆根尖微核率无明显影响。更多还原

【Abstract】 Effects of two pesticides, imidacloprid[1- (6- chloro-3 -pyridylmethyl) -N- nitro- imdazolidin -2- ylideneamine] and RH-5849[2-benzoy-1-tert-butylbenzoylhydrazine],on the rates of micronucleus formation in root tip cells of Allium sativum and Vicia faba, respectively are studied in the present investigation. Compared with negative control group, results showed that rates of micronucleus formation in the Allium sativum and Vicia faba were not remarkably different (P>0.05), but significantly different (P<0.01) when compared with positive control. The results indicated that neither imidacloprid nor RH-5849 exhibited significant effects on the micronuclei frequency in root tip cells of Allium sativum and Vicia faba.更多还原
