Abstract:
In this paper,we studied the effect of Pb,Ca and their combined treatments on root cell mitosis of soybean(2n=40)cultivar Heihe 26.The results showed that with the concentration of Pb(NO3)2 (0-100 mg.L-1)increased the rate of chromosome aberration and micronucleus rate increased,and the mitotic index decreased.Lower concentration of Ca(NO3)2(0.1-1.0 g.L-1)could enhance the plant root tip mitosis index,but inhibited that at high concentrations(2.5 and 4.5 g.L-1).In the Pb(NO3)2 and Ca(NO3)2combined treatment,0.1-1.0 g.L-1Ca(NO3)2 could relieved the poison of 50mg.L-1Pb(NO3)2.
