摘 要:

弱光是目前制约设施生产的重要环境因子之一。植物为了适应弱光环境, 通过改变自身的生理生化特性, 如叶绿素 含量、叶片解剖结构、类囊体结构、抗氧化酶活性和内源激素含量等, 从而保证植物体自身能在遮荫的条件下充分利用光能。本文从生长发育、光合特性、活性氧代谢、组织结构和激素等方面综述了植物对弱光的响应规律。

Abstract:

Weak light is currently one of the important environment factors of restricting facilities production. The plant transforms oneself the physiological and biochemical characteristic for adapting to weak light, such as chlorophyll content, leaf anatomy organization, thylakoid structure, antioxidant enzyme activity and endoge-nous hormone content etc., to insure plant can well make use of light under the situation of shading. This review summarizes the rule of response to weak light from plant growth and development, photosynthetic characteris-tics, reactive oxygen metabolism, tissue structure and hormone.

Key words: plant; weak light; morphology; photosynthetic characteristics; response rule
