Experimental Study on Micronucleus in Root-Tip Cells of Vicia faba Induced by Three Pesticides

  • Micronucleus(MCN) test of Vicia faba root-tip was conducted to study the mutation inducing effect of three pesticides: methamidophos(Me),thiophanate-methyl(Th) and moroxydine hydrochloride(Mo) in their normally used concentrations.When each of the three pesticides is used alone,the micronucleus frequencies(MNF) of Vicia faba root-tips of the three test groups are higher than those of the control group(P0.01),showing a dosage effect,and Mo gives more obvious inductive effect than the other two pesticides do.When the three pesticides are used together,the high concentration groups show antagonistic actions,the middle and the low concentration groups show synergistic actions,and different concentrations of the pesticides do not exhibit dosage effects.The optimum concentrations of the pesticides are 0.230 0 to 0.250 0 g·L-1 for Me,0.468 0 to(0.526 0 g·L-1)for Th,and 0.055 6~0.059 2 g·L-1for Mo.
