Abstract:
Taking simple static fumigation system for potted seedlings fumigation treatment，different concentrations of SO2 influencing on Prunus×cistena ‘Pissardii’ antioxidant enzyme activity，malondialdehyde，proline content，lipid peroxidation，soluble protein content，and leaf fluid pH were studied.The results showed that with the increase of SO2 concentration，leave of Prunus×cistena ‘Pissardii’ peroxidase (POD)，superoxide dismutase (SOD)，and catalase (CAT) activity increased，malondialdehyde (MDA)，membrane permeability increased，proline and pH of leaf drop.When the concentration of SO2 exceeded 17.10 mg/m3，the antioxidant enzyme system had been severely damaged.
