Abstract: The micronucleus and abnormal division in Allium sativum 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.

Key words: Allium sativum, micronuclei, abnormal division, pro-micronuclei
