摘要
Abstract
[Objective] To study the genotoxicity and cytotoxicity in root tip cells of maize with different concentration of Ce(SO4)2.[ Methods] This study was designed to assess the potential induction of micronuclei by Ce(SO4)2 with different concentrations in the roottip cells of maize(Zea mays L). [Results] The results showed that the frequency of micronuclei(FMN) increased significantly at the concentration of Ce( SO4)2 over 10 mg/L and the mitosis index(MI) decreased when the concentration of Ce( SO4)2 reached 1000mg/L.[Conclusion] It suggests that Ce(So4)2 has genotoxicity and cytotoxicity to root tip cells of maize.关键词
