Abstract: The purification effect of 3 important landscaping plants, green dill, ivy and chlorophytum, on contaminant gas SO2 was studied. The contents of malondialdehyde (MDA), superoxide dismutase (SOD), peroxidase (POD) and chlorophyll (Chl) in these plants under fumigation with SO2 of different concentration were analyzed. The results showed that the activity of these antioxidase and physiological indices changed differently with an increasing in concentration of SO2. The MDA in these plants increased significantly, with ivy the highest and green dill the lowest. The SOD in ivy and chlorophytum exhibited an increase followed by a decrease, while the SOD in green dill decreased significantly. The POD in all plants increased and then decreased significantly; the maximum concentrations of POD under a SO2 gas 60 mg/m3 was 1.58, 2.34 and 0.07△OD470/(min·mg) for green dill, ivy and chlorophytum, respectively. Content of Chl decreased significantly with ivy showing the largest effect and green dill showing the smallest effect.
