| 摘 要： | 高温胁迫下高羊茅叶宽、生长强度和生理代谢都发生了明显变化,从而影响草坪质量.研究结果表明,随着温度的升高,8月高羊茅草坪质量、叶宽、生长强度、叶片含水量以及叶绿素含量显著下降(p《0.05);在8-9月份期间,高剪和中剪高羊茅草坪质量显著优于低剪(p《0.05);在高温期间高剪和中剪的高羊茅叶片叶绿素含量较高,且较5月下降幅度小;高剪和中剪的生长强度和叶片含水量在高温阶段下降幅度小.

| Abstract: | Heat stress brought marked variations in leaf width,growth rate and physiological metabolism of tall fescue,influencing turfgrass quailty.The results indicated that turfgrass quality,leaf width,growth rate of tall fescue,the contents of leaf water and chlorophyll decreased significantly (p<0.05) with increasing temperature in August.Turf quality with high and moderate mowing height was better than that with low mowing height during August and September.Leaf chlorophyll with high and moderate mowing height showed higher content as compared with low mowing height,their reduction extent in August was lower than that in May.This indicated that growth rate and leaf water content decreased slowly with high and moderate mowing height in heat stress. |
