摘要
生长在特殊环境条件下(如低温和强辐射)的植物经常会遭受光氧化胁迫。植物通过一系列光保护机制来抵御光氧化伤害,这些机制反映了植物在生理和生化以及形态结构等方面对强光环境的适应性。本文对近年来有关强光下植物适应性的研究现状进行了综述,总结了植物光保护和避免光抑制的相关机制,认为植物的各种防御机制的协同作用是抵御高光强下光氧化和光胁迫的有效途径。
Due to special living conditions of low temperature and intense radiation,plants are easily subjected to photo-oxidation.However, series of photo-protective mechanisms can lessen or even eliminate photo-oxidation,reflecting the adaptation of plants to the high light intensity environments. Mechanisms of photo-protection and avoidance of photo-inhibition are summarized based on recent studies on plant photosynthetic acclimation to high light radiation environments.
