四种暖季型草坪草对SO2的抗性及净化能力的比较
A study on resistance and purifying ability of SO2 on four warm-season turfgrasses
摘要
Abstract
The influence of sulfur dioxide (SO2) on four warm-season turfgrasses [centipedegrass (Eremochloa ophiuroides) , zoysiagrass (Zoysia japonica) , bahiagrass (Paspalum notatum) , bermudagrass (Cynodon dac-tylon)] were studied using fumigation to apply five SO2 treatments: CK (Natural state), S1 (1. 5 mg/L), S2 (2. 25 mg/L), S3 (3 mg/L) and S4 (3. 75 mg/L). There was a negative correlation between total chlorophyll and SO2 concentration but positive correlations between soluble protein, malondialdehyde, proline, peroxidase (POD) , catalase (CAT), superoxide dismutase (SOD) , leaf sulfur content and SO2 concentration; The soluble protein content increased except for bermudagrass. By the fuzzy membership function, the resistance of four turfgrasses to SO2 was in the order: bermudagrass＞zoysiagrass＞bahiagrass＞centipedegrass; and the purifying ability was in the order: zoysiagrass＞bahiagrass＞bermudagrass＞centipedegrass.关键词
