外源物质对干旱条件下植物光合荧光影响

Effects of exogenous substance on photosynthesis and fluorescence in plants under drought stress

为研究外源物质对干旱条件下植物光合荧光作用的影响,采用不同实验探究了营养元素、激素和多胺以及其他物质对植物光合荧光作用的影响.发现在干旱条件下,上述这些外源物质能够在一定程度上提高植物的光合荧光作用,提高植物的抗旱性.为提高植物的抗旱性研究提供理论基础.

In order to research the effects of exogenous substance （nutrients, hormones, polyamines and other substances）on photosynthesis and chlorophll fluorecence in plants under water stress, different experiments were reviewed in this paper. In conclusion, these substances can improve drought resistance of plants and provid fundamental basis for drought resistance in plants.
