摘  要:
植物的光合作用是易受环境影响的重要生理过程之一.高山植物作为生长在特定极端环境(低温/强辐射)下的植物群体,其光合器官在形态结构和生理功能上形成了抵御强辐射和低温胁迫的特殊适应机制.但由于较高的生境异质性,高山植物的光保护适应机制存在较大的差异.光保护适应机制与光合作用密切关联,影响植物的碳同化能力和生物量的形成能力.本文对近年来国内外有关高山植物光合器官叶绿体的形态、超微解剖结构及光合机构光保护适应机理的研究进展进行了综述,并提出了今后高山植物光合作用生理适应性研究的方向.

摘  要:
Photosynthesis is one of the vital physiological processes easily affected by environmental changes.As a plant group growing in specific low temperature and strong irradiance environment,the photosynthetic apparatus of alpine plants have developed special morphologically and physiologically mechanisms in adapting to this extreme adverse environment.However,due to the high heterogeneity of habitats,there exist great differences in the photo-protection and adaptation mechanisms among different alpine plants.This paper reviewed the recent researches about the morphology and ultramicro-anatomical structure of the chloroplasts in photosynthetic apparatus of alpine plants and the photo-protection and adaptation mechanisms of the plants,and proposed the further research directions on the physiological adaptation of the photosynthesis of alpine plants.
