水杨酸对植物光合作用影响的研究进展

Research Progress on the Impact of Salicylic Acid on Plant Photosynthesis

水杨酸作为一种信号分子,对植物呼吸代谢、种子萌发、成花诱导、衰老及抗逆等生理过程都有调节作用,近年来有关水杨酸对植物光合作用影响的研究取得了很大进展。水杨酸能够调节植物叶片气孔运动、光合色素含量、光合机构性能、光合碳同化酶活性等各方面,其效果因浓度、植物种类、环境条件等不同而表现出差异。该文就近年来国内外有关水杨酸对植物光合作用的影响(主要从植物叶片气孔运动、光合色素含量、光合机构性能和光合碳同化酶活性等方面)研究进展进行综述。

Salicylic acid,as a well-known signal molecule,has significant effects on various physiological processes,such as respiratory metabolism,seed germination,floral induction,senescence,and stress resistance.In recent years,great progress has been made on its effects on photosynthesis.Salicylic acid has the ability to regulate stomatal movement,photosynthetic pigment content,photosynthetic machinery and carbon assimilation,and may display different effects with different concentrations,plant species,and environments.Centering on stomatal movement,photosynthetic pigment content,photosynthetic machinery and carbon assimilation,this paper summarized the research progress on the effects of salicylic acid on photosynthesis.
