中文摘要：
在非生物胁迫中,高温是影响草坪植物特别是对冷季型草坪草生长和发育最重要的生态因子之一. 高温胁迫会导致冷季型草坪草生长受到抑制、草坪质量下降、草坪植株体内的生理生化代谢紊乱,细胞内产生大量氧自由基,使膜脂过氧化,植株体内蛋白质变性,最后导致细胞死亡. 因此,如何提高冷季型草坪草的耐热性是目前冷季型草坪在热带、亚热带地区建植能否安全越夏的重要问题. 文中综述了国内外冷季型草坪草耐热性调控的研究进展, 在阐明冷季型草坪草耐热性调控原理的基础上,报道了用于草坪草耐热性鉴定的形态、生态、生理和生化等指标,以及通过降低土壤温度、叶面喷施生长调节剂、施肥、灌溉和修剪等养护管理措施来提高冷季型草坪草的耐热性研究进展.
英文摘要：
Among abiotic stresses, high temperature is one of the important ecological factors limiting the growth and development of cool- season turfgrass in the transitional and warm climatic regions, especially during hot summer, which leads to the decline of turf quality, loss of chlorophyll, metamorphism of protein, decrease of photosynthetic activities, and even, cell death. Therefore, how to overcome the difficulty for cool-season turfgrass in spending hot summer successfully, especially in the transitional and warm climatic regions, is a serious problem. Based on the statement of regulation principle in thermotoleranee, the research advances in thermotoleranee regulation of cool - season turfgrass were reported, including the advances in morphological, ecological, physiological, and biochemical characters in thermotolerance, and the advances in thermotoleranee regulation by proper management and regulation measurements such as lowing the soil temperature, application of growth regulators and fertilization, proper clipping, and irrigation.
