Abstract

A pot experiment was performed to study the effect of EDTA (0, 1.5, 5.0 mmol/kg) on the cadmium (Cd) accumulation ability of Solanum nigrum L. grown in different Cd-contaminated soils (0, 5, 10, 25, 50, 100 and 200 mg/kg). Meanwhile, soil Cd mobility was evaluated. Results showed that there were significant interactions between Cd and EDTA. Low EDTA dosage (1.5 mmol/kg) significantly alleviated Cd stress to S. nigrum L., although EDTA inhibited the growth of S. nigrum L. grown in non-contaminated soil. High EDTA dosage (5 mmol/kg) could deteriorate Cd stress to S. nigrum L. EDTA could significantly increase the mobility of soil Cd and the Cd content in plant. This research indicated that low EDTA dosage (1.5 mmol/kg) was efficient in assisting remediation of Cd contaminated soil by S. nigrum L. and could lessen second pollution.
