ABSTRACT
Objective To study the genetic toxicity of magnesium sulfate to the root tip cells of Vicia faba. Methods The root tip cells of Vicia faba with 1.5-2 cm root tip were taken as the subjects and were exposed to magnesium sulfate of different concentrations(0.50%-2.00%) for 6 h. In the other test,the cells were treated with 1.5% magnesium sulfate for 2,4,6,8 and 10 hours respectively. The distilled water and potassium dichromate (0.05%) were used as the negative and positive control respectively. The micronucleus and the chromosomal aberration were calculated after 24 hours of culture. Results Compared with the negative control group,0.1%,0.15%,0.175% and 0.2% of magnesium sulfate increased the micronucleus and 0.05%,0.1%,0.15%,0.175%,0.2% of magnesium sulfate increased the chromosomal aberration in Vicia faba root tip cells. Compared with the control group (0 h),both of the micronucleus and the chromosomal aberration of Vicia faba root tip cells increased (P
