【摘要】 在农药普尔泰的正常使用浓度范围内,用不同浓度的普尔泰分别处理蚕豆根尖细胞4h和8h,监测其细胞微核诱变情况。结果表明,普尔泰对蚕豆根尖细胞微核的诱变,随着处理液浓度的增加、处理时间的延长,具有良好的剂量效应关系。用蒸馏水作对照处理,经t检验,差异极显著,说明普尔泰对蚕豆根尖细胞有明显的诱变作用。更多还原

【Abstract】 Within the scope of density ofnormal use of the agrochemical Jingangmycin Bacillus cereus,use different density degree of Jingangmycin Bacillus cereus to handle the Vicia faba’s root tips cell for four hours and eight hours, and monitor mutagenicity.of micronucleus The result shows that jingangmycin Bacillus cereus along with handling the density of liquid increasely and handling time longer, which has the good dosage effect in the Vicia faba root tips. using distilled water to compare with it and according to examine by t, they have obivious difference. So the Jingangmycin Bacillus cereus has an obvious mutagenicity function on the Vicia faba’s root tips cell.更多还原
