关于植物激素对光合作用影响的问题曾有许多学者研究过。和首先通过试验证明,植物生长素(吲哚乙酸)能促进大麻、八仙花叶子的光合作用。用植物生长素溶液(10—30mg/L)处理幼龄菜豆、大豆、向日葵、小麦和其他一些植物的叶子,也有类似的作用。但是,植物生长素对玉米和已长成的菜豆叶子却无任何作用。现在知道的有关其他植物激素对光合作用影响的研究结果不尽一致。有的试验表明,用 Many scholars have studied the effects of plant hormones on photosynthesis. And first of all, it has been proved through experiments that auxin (indole acetic acid) can promote the photosynthesis of cannabis and hydrangea leaves. Plant auxin solution (10-30mg / L) treatment of young bean, soybean, sunflower, wheat and other plant leaves, also have similar effects. However, auxins have no effect on corn and bean plants that have grown. What we now know about the effects of other plant hormones on photosynthesis is not consistent. Some experiments show that
