Abstract:
Objective To investigate the cytogenetic toxic effects of copper sulfate on root tip cells of Zea mays L.Methods The root tip cells of Zea mays L were treated by copper sulfate as mutagen at the doses of 0.05,0.10,0.25,0.50,1.00 g /L for 24 hours.The mitotic index,the micronucleus rate and the chromosome aberration rate of tip cells of Zea mays L were measured.Results Compared with the negative control group,the micronucleus rates and the mitotic index in 0.05,0.10,0.25,0.50,1.00 g /L groups and the chromosome aberration rates in 0.05,0.10,0.25,0.50 g /L groups increased significantly(P
