Abstract
[Objective] The research aimed to study the effect of malachite green (MG) on mitosis of Vicia faba root tip cell. [Method] Dif ferent concentrations of malachite green were used to treat Viciafaba root lip cell for 12.24,36,48 and 72 h.The mitosis of Vieia fa a root tip ceil was observed by conventional chromosome compression technology ,and the mitotic index ( MI) of each treatment group was counted. [ Re sult] As the treated time prolonged,MI presented the M-shaped variation trend,which illustrated that Vicia faba root tip had a adaptive process to MC. As the concentration of MC increased,Ml gradually rote. When the concentration of MG was during 0.50 - 1. 00 mg/L, Ml was the maximum. When the concentration of MG further increased,MI decreased. It showed that MG was favorable for the plant growth in the certain concentration range. [Conclusion] The research could provide the basis for the reasonable utilization of MG,and the reference for evaluating the environmental harm of MG.关键词
