Abstract
The two-year-old seedlings of Parthenocissus tricuspidata,Jasminum mesnyi and Rosa multiflora were exposed to different concentrations of sulfur dioxide(SO2) in the closed fumigation chambers to study the effects of SO2 on their MDA contents and protective enzyme(SOD,POD,CAT) activities in leaf.The results showed that MDA contents and POD activities of three vertical greening plant species were increased with the increases of concentration of sulfur dioxide,while SOD and CAT activities decreased.The degrees of increase or decrease varied with the plant species and SO2 concentrations.Conclusively,J.mesnyi was exhibited stronger resistance to SO2,followed by P.tricuspidata and R.multiflora.
