摘　　要：对植物细胞膜、细胞相对含水量与渗透调节、光合与呼吸作用、活性氧与抗氧化系统等多个影响冷季型草坪草耐热性能的生理生化指标和外观指标进行了综述,旨在为筛选耐热性冷季型草坪草种,开展草坪草耐热机理的研究提供理论依据,也总结了通过合理的栽培管理措施、抗热锻炼、外施化学物质和生物技术的运用来提高冷季型草坪草耐热性的研究进展。This paper reviewed several thermotolerance indexes of cool-season turfgrasses, including cell membrane,relative water content,photosynthesis and respiration,reactive oxygen and antioxidant systems,in order to select the species whice had better heat tolerance and provide theory to research turfgrasses thermotolerance mechanism. It also reviewed the research advances in increasing the heat tolerance of cool-season turfgrasses by proper management.heat acclimation,chemical components application and biotechnology.
