外文摘要：The effects of methyl 1-(3, 3-dimenthyl-2-oxobutyl)-1H-1, 2, 4-triazole-3-carboxylate (CGR(3)) and 1-(3,3-dimethyl-2-oxobutyl)-1H-1, 2, 4-triazole-3-carboxylic acid (CGR(3-1)), as two new plant growth regulators, on photosynthetic characteristics and mung bean yield were investigated in this study. Both regulators improved the net photosynthetic rate (P N ), stomatal conductance (gs), intercellular CO2 concentration (Ci) and transpiration rate (E); CGR(3-1) had a larger impact than CGR(3). In terms of photosynthetic efficiency, CGR(3-1) showed higher effectiveness. Considering photosynthetic pigments, the two regulators enhanced the contents of chlorophyll a, chlorophyll b, chlorophyll (a+b) and carotenoid. The application of CGR(3-1) (CGR(3)) significantly increased (decreased) the contents of soluble sugar and starch. The results indicated that CGR(3-1) was more effective in improving the photosynthetic characteristics and yield of mung bean and can be a widely adopted strategy for producers.
