Abstract/Contents:"The chlorophyll content, membrane lipid peroxidation, osmoregulation substances, and protective enzyme activity of four cold-season turfgrass species (Fescue arundinacea, Lolium perenne, Poa pratensis; Agrostis stolonifera) treated with SO2 (1.45, 2.15, 3.56, or 5.01 mg/m3) were measured using artificial simulation, and the resistance to sulfur was evaluated. The MDA content increased to different extents in these four turfgrass species which indicated that the membrane systems were injured under the SO2 stress. F. arundinacea and L. perenne had increased antioxidant enzyme activities (SOD, POD and CAT) and accumulated compatible solutes content (soluble sugar and proline) against low level SO2 stress but high concentrations of SO2 had a significant effect on them. Additionally, A. stolonifera and P. pratensis had a poor resistance to SO2 toxicity that was directly reflected in the observed appearance, especially for P. pratensis. The damage increased with SO2 concentration. The results of a comprehensive evaluation showed that the SO2 resistance of the four species decreased in the order F. arundinacea, L. perenne, A. stolonifera, and P. pratensis. The turfgrass species F. arundinacea and L. perenne would be suitable for urban landscaping in SO2 polluted areas."
