Abstract
The effects of cadmium(Cd) on the plant growth,activities of antioxidant enzymes and contents of antioxidants in leaves of mung bean(Phaseolus aureus) and common vetch(Vicia sativa) were investigated using hydriponic experiments.Cadmium at 100 μmol·L-1 significantly decreased the main root elongation and roots dry weight,and increased activities of superoxide,dismutase(SOD),catalase(CAT),ascorbate peroxidase(APX) and guaiacol peroxidase(GPOD) in the leaves of both species.Activity of glutathione reductase(GR) in V.sativa leaves increased,and content of ascorbic acid(ASC) remained unchanged with Cd exposure time,whereas reduced glutathione(GSH) appeared to decrease for initial 6 days and then increased.But in P.aureus leaves,activity of GR and contents of GSH and ASC decreased with Cd exposure time.Compared to P.aureus,V.sativa had higher activities of SOD,CAT,APX and GR,and contents of ASC and GSH in the leaves under Cd stress.In contrast,V.sativa leaves had lower GPOD activity than P.aureus.Results from native PAGE showed that Cd treatment with 100 μmol·L-1 also changed the isozyme patterns of these antioxidant enzymes in the leaves of both species.The results suggested that tolerance of V.sativa to Cd could be attributed,at least in part,to its antioxidant capacity than P.aureus.
