Abstract
In order to understand the effects of soil cadmium(Cd2 +)on crop seed germination and reveal the mechanism of the impact on crop,hydroponic culture was used to study the impact of different concentrations of Cd2+solution(0,3,6,9 mg·L-1)on soybean seed germination.The germination rate,germination energy,germination index and vigor index were investigated under the Cd2+stress.Under 3 mg·L-1 Cd2+ solution treatment,the germination rate was less affected,while seed germination index and vigor index were all higher than those of control.With the Cd2+ solution concentration increased,the germination rate,germination index and vigor index decreased gradually,and seed germination energy decreased significantly.Results indicates that lower concentration of Cd2+ could promote seed germination,while higher concentration of Cd2+ could inhibit seed germination in soybean.
