摘要
研究污染的河水对大蒜根尖细胞微核的诱导及细胞分裂的效应。结果表明,较重污染(PI=7.63)的河水对大蒜根尖染毒24 h以上,致使其有丝分裂指数下降明显(p<0.05),诱发间期细胞微核显著(p<0.01),导致有丝分裂异常和前微核的产生。
The micronucleus and abnormal division in Allium sat＆um root tips induced by polluted river water were investigated. The results showed that the mitotic index （MI） decreased（p 〈 0. 05 ） and the micronuclei rate increased （p 〈 0. 01 ） （treated for 24 h ） when river water was polluted hard （PI = 7.63 ）. Meanwhile, some abnormal mitosis phenomena and pro-micronuclei were observed.
