摘　　要：对5种不同草坪草的耐旱性进行了研究。研究结果表明,在干旱胁迫下,各草种的根冠比、Pro含量和SOD活性增加,MDA含量与耐旱性呈负相关。较耐旱的草种为硬羊茅和紫羊茅。The drought tolerance of five lawn varieties was studied. The results showed that the shoot root ratios and contents of Pro and SOD activities increased in all lawn varieties under drought stress, the contents of MDA and drought tolerance were in a negative correlation. Festuca ovina ev. Osprey and Festuca ruhra L. cv. Pernille were droughttolerant grasses.
