逆境条件下外源水杨酸对植物光合特性的影响研究进展

Research Progress on Relationships between Salicylic Acid and Plant Photosynthesis in Stress Conditions

为推动水杨酸在农业生产中的应用,实现各种逆境条件下农业生产栽培模式的简化,进而提高农产品品质,从光、温度、水分、盐以及重金属胁迫等方面,综述了水杨酸对植物抗逆过程中光合特性影响的研究进展。一定浓度的水杨酸作用于不同逆境中的植物后,均可从不同角度影响或调节植物的光合作用,进而提高植物的经济指标。并对水杨酸的应用前景进行了展望,水杨酸在植物分子水平上的作用机制是今后研究的重点。

To promote the use of salicylic acid in agricultural production, simplify the cultivation mode in stress conditions and improve the quality of agricultural products,this paper author summarized the research progress of salicylic acid application and its effects on plant photosynthesis under stress conditions of light, temperature, water, salt and heavy metal. A certain concentration of salicylic acid had different impacts on plant photosynthesis, so could improve the economic index of plants. The application prospect of salicylic acid was discussed. The research focus in the future should be put on the application of salicylic acid at plant molecular level.
