Organic acids were added into soil, to study the effects of organic acids on mobilization of cadmium in soil and its uptake by wheat plant (Triticum aestivum L.).It was shown that organic acids could mobilize soil Cd, the sequences of mobilizing ability of organic acids were followed EDTA>wheat root exudate>citric acid>malic acid>water.However, EDTA decreased Cd content in shoot, and wheat root exudate collected under Fe-deficient stress significantly increased Cd content in shoot.Compared to the control, citric acid and malic acid also increased Cd content in shoot.
