摘要
草坪草有着调节气候和改善生态的重要作用。农业可用水资源有限严重影响草坪草的生长发育,提高草坪草的抗旱性有助于缓解这一问题。该文综述了草坪草在干旱胁迫下的抗氧化系统、渗透调节、激素系统、大分子和微生物物质在生理生化层面的变化情况以及抗旱相关基因、利用组学技术解析抗旱机制等方面的研究进展,对目前草坪草抗旱性研究的重点问题进行分析,并对研究前景进行展望,以期对接下来草坪草的抗旱性研究提供信息资源和参考依据。
Turfgrass has an important role in regulating climate and improving ecology.The limited water resources available for agriculture seriously affects the growth and development of turfgrass,and improving the drought tolerance of turfgrass can help to alleviate this problem.This study summarized the research progress on the physiological and biochemical mechanisms of antioxidant,osmoregulation,hormone,and microorganisms,and the molecular mechanisms of drought-related genes and multiple genomics of turfgrass under drought stress.The key issues of the current research on turfgrass drought resistance and future prospects pertaining were also discussed,in order to provide information resources and references for the next research on drought resistance of turfgrass.
