The effect of Cu2+ in different concentrations on the germination of maize was studied. It was shown that Cu2+ could raised the bud growth and biomass when Cu2+ lever was range from 0.5mg/L to 1mg/L, but when the lever was over 1mg/L, the promotion became more and more less until it became restrain. High level Cu2+ was harmful to the germination and growth of maize. Cu2+ has more influence on root growth of maize than on its bud.
