Abstract
Effects of Cd,Zn,separately and in combination,on the root growth of three kinds of beans have been investigated by water-culturing experiments.The results showed that at 2 mg·kg-1 Cd the germination of the three beans was higher than the control group.The germination index of soy bean decreased with the increase of Cd concentration.There was a negative correlation between germination index of soy bean and Cd concentration.There was no effect on the germination index of mung bean and pea,and the root growth of the three beans was inhibited,especially for mung bean.After 24 h the roots of the three beans became putrescence or stopped growing Zn had no effect on the germination of the three beans.As Zn concentration was lower(Zn2+15 mg·kg-1),the growth of the roots was stimulated,and the inhibition on the root growth decreased with the increase of Zn concentrations,especially for mung bean.The inhibition rates increased with the increase of Zn concentrations,and the root growth was inhibited(20 mg·kg-1).With 20 mg·kg-1 Cd,the inhibition rates decreased with the increase of Zn at low concentration(Zn2+15 mg·kg-1),and the growth was stimulated.At Zn2+15 mg·kg-1,Cd and Zn inhibited together.The inhibition rates increased with the increase of Zn concentrations,and the roots growth was inhibited when the concentration of Zn was 20 mg·kg-1.
