摘    要:植物花青素广泛分布在植物的根、茎、叶、花和果实等器官中,是植物形态建成过程中或响应逆境而产生的一种次生代谢物质.植物叶片中的花青素具有特殊的化学结构和光谱特性,在光破坏防御机制方面发挥了重要的作用,已经成为植物光合生理生态的研究热点.本文综述了近年来植物叶片花青素与光合作用的研究进展,从叶片花青素的分布、光谱特性及其与光合色素的关系等方面说明花青素对植物光合作用的影响,重点介绍了叶片花青素通过光吸收、抗氧化剂和渗透调节等在植物光破坏防御机制方面的作用,展望了今后的主要研究方向

关 键 词:花青素  光抑制  光破坏防御

Abstract:Anthocyanin is widely distributed in plant organs such as root, stem, leaf, flower and fruit, being a kind of secondary metabolites generated in plant morphogenesis or for stress response. Leaf anthocyanin has special chemical structure and spectral properties, playing important roles in plant photoprotection, and becomes a hotspot in plant photosynthetic physiological ecology. This paper summarized the recent research progress in the effects of leaf anthocyanin on plant photosynthesis, including the distribution of leaf anthocyanin, its spectral properties, and its relationships with photosynthetic pigments, with the focus on the potential mechanisms of anthocyanins photoprotection, including light absorption, antioxidation, and osmotic regulation. The further research directions on the effects of leaf anthocyanin on photoprotection were proposed.
Keywords:anthocyanin  photoinhibition  photoprotection
