摘要: 本实验采用人工模拟熏气法,以CK(自然状态)、S1(1.5 mg/L)、S2(2.25 mg/L)、S3(3 mg/L)、S4(3.75 mg/L)5个SO2浓度水平,对4种暖季型草坪草——假俭草、结缕草、百喜草、狗牙根进行密闭熏气处理;进而测定4种草坪草生理生化指标;最终比较4种草坪草对SO2的抗性和净化能力。结果表明,4种草坪草叶绿素总量随SO2浓度增加呈降低趋势;可溶性糖、丙二醛、脯氨酸、超氧化物歧化酶、过氧化氢酶、过氧化物酶、叶片硫含量则随SO2浓度增加呈升高趋势;可溶性蛋白除狗牙根降低外其余均呈升高趋势。采用模糊数学隶属度公式进行综合相关分析得出,4种草坪草对SO2的抗性比较:狗牙根>结缕草>百喜草>假俭草;净化能力比较:结缕草>百喜草>狗牙根>假俭草。

Abstract: The influence of sulfur dioxide (SO2) on four warm-season turfgrasses [centipedegrass (Eremochloa ophiuroides), zoysiagrass (Zoysia japonica), bahiagrass (Paspalum notatum), bermudagrass (Cynodon dactylon)] 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.
