草坪植物耐弱光机理研究进展

摘要

在遮荫胁迫下,草坪植物形态特征、解剖结构、光合器官、抗氧化物酶、内源激素以及营养元素的吸收和积累等都会发生一系列变化.本文阐述了草坪植物耐弱光逆境研究的意义、弱光逆境对植物的形态及生理的影响、植物对弱光逆境的生理响应机理和光合调控机制,并对当前草坪植物耐弱光逆境胁迫的研究方向提出自己的看法,旨在为今后的相关研究提供建议.%A series of changes of turf grass morphology, anatomical structure, photosynthetic organ, antiox-idant enzymes, endogenous hormones, and absorption and accumulation of nutrients occurred under low light stress. This short review reports the importance of research on turfgrass shadow tolerance. The effect of shadow environment on turfgrass morphology and physiology; the mechanism of physiological response; and the photosynthetic regulation were summarized. Current research problems were also discussed to provide insight for future relevant research.
