耐荫性是植物在低光环境下的生存和生长能力,对森林植物群落演替起重要作用,植物对遮荫的适应机制已成为生态学的研究热点.本文综述了森林植物的耐荫性及其在形态和生理方面的适应性,分析了森林植物在生长性状、生物量分配、树冠结构、叶片形态生理、叶片解剖结构、光合参数、碳水化合物分配、水分和养分的利用等方面对遮荫产生的可塑性响应,最后对目前研究存在的问题进行了分析,展望了未来的研究内容和方向.
Shade tolerance is the plant’s survival and growth ability in low light environment, which plays an important role in the succession of forest plant community, and the adaptation mechanism of plants to shading has become a hot research topic in ecology.In this paper, the shade tolerance And its morphological and physiological adaptability. The effects of cover on the growth traits, biomass allocation, canopy structure, leaf morphological physiology, leaf anatomy, photosynthetic parameters, carbohydrate distribution, utilization of water and nutrients were analyzed Finally, the problems existing in the current research are analyzed and the future research contents and directions are prospected.
