Changes in malondialdehyde (MDA) content and the activities of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) in endosperms and cotyledons during Jatropha curcas seed germination were investigated in the present study. MDA content in endosperms increased during 10 day of germination, while in cotyledons it increased during six day of germination and then decreased. SOD activity in endosperms showed an increase at two day of germination and decreased gradually, while in cotyledons it increased gradually during germination. POD activity in endosperms increased gradually, peaking on 8 day of germination, while it peaked at 6 day in cotyledons. CAT activity in endosperms and cotyledons rose gradually, peaking on 8 day and 6 day of germination, respectively. Analysis by electrophoresis showed that the changes in patterns and intensities of SOD, POD and CAT isoenzymes in endosperms and cotyledons during germination appear to be depended on developmental processes.
