Title: Utilization of micronucleus test technique in Vicia faba root tips to evaluate the genetic toxicity of three heavy metal ions.
Abstract:Micronucleus test,micronucleus frequency and mitotic index of root tip cells of Vicia faba were used to study the genetic toxicity of different concentrations of heavy metal ions,namely Pb2+,Cr3+ and ...Micronucleus test,micronucleus frequency and mitotic index of root tip cells of Vicia faba were used to study the genetic toxicity of different concentrations of heavy metal ions,namely Pb2+,Cr3+ and Cd2+.The results showed that different heavy metal ions could induce the occurrence of micronucleus.The highest genetic toxicity was found for Cd2+,the medium for Pb2+ and the lowest for Cr3+.Within certain concentrations of different heavy metals,micronucleus frequency increased with the increase of concentration,and micronucleus frequency decreased at the highest concentration.Mitotic index increased in some certain low concentration and decreased in high concentration of heavy metal ions.The results implied that cell karyokinesis could be promoted at low concentration and be restrained at high concentration.Read More
