植物遮荫效应的研究进展

Study on the Shading Impact on Plant

植物为了适应遮荫的环境,改变自身的生理生化特性,如叶绿素含量、光合特性、蒸腾特性、气孔导度、与光合作用相关的酶、膜脂过氧化物酶、膜保护酶活性、内源激素含量、游离脯氨酸含量及花色素苷含量等,从而保证植物体自身能在遮荫的条件下充分利用光能进行正常的生命活动。现从遮荫对植物生长环境、生长发育、生理生化特性等方面的影响介绍目前的研究进展。

In order to adapt to the shade environment, plants change their physiological and biochemical characteristics such as chlorophyll content, photosynthetic characteristics, transpiration characteristics, stomatal conductance, and photosynthesis-related enzymes, membrane lipid peroxides, membrane protective enzyme activity, endogenous hormone content, free proline content and anthocyanin content. These changes assured plants to make the most of light energy to carry out normal life activities under the shade environments. We introduced the progress in the shade impact on plants growing enviroments, plants growth and development, and plants physiological and biochemical characteristics.
