Effect of copper disposal on germination and young plant growth of soybean and mung bean

The experimentation adopted the method of indoor water cultivate,studied the effects of different copper concentration on germination and physiological and biochemical indexes of legume seed.As a result,after deal with the same copper concentration on mung bean and soybean,the effect of copper concentration on germination percentage of soybean seed was less than mung bean,high copper concentration had a little restrain effect on germination exponential of legume seed.POD activity of mung bean was increased first,then downward;however POD activity of soybean was upward trend.the copper concentration of threshold value for MDA appearance was different between two kinds of legume,mung bean appeared the threshold value on 300μmol/L, yet soybean was 500μmol/L.Soybean is more than suitable for copper in the soil.
