The rot and deterioration of sprouts are closely related to their physiological state and postharvest storage quality. The study investigated the influences of brassinolide, zeaxanthin, and their combination on physiological metabolism, chlorophyll fluorescence, and nutritional quality of radish sprouts stored at 4 °C. The combined treatments enhanced hypocotyl length, fresh weight, contents of secondary metabolites, nutritional ingredients, glutathione, the photoprotective capacity of PSII, and FRAP level in radish sprouts compared with zeaxanthin alone. The combined treatments enhanced hypocotyl length, fresh weight, glutathione content, F/F value, and antioxidant capacity in sprouts compared to brassinolide alone. The combined treatment of zeaxanthin and brassinolide could make radish sprouts keep high biomass and antioxidant capacity by increasing the contents of stress-resistant metabolites and by weakening the photoinhibition of PSII in radish sprouts stored at 4 °C.
豆芽的腐烂变质与其生理状态和采后贮藏品质密切相关。本研究调查了油菜素内酯、玉米黄质及其组合对4℃贮藏的萝卜芽苗菜生理代谢、叶绿素荧光和营养品质的影响。与单独使用玉米黄质相比,联合处理提高了萝卜芽苗菜的下胚轴长度、鲜重、次生代谢产物含量、营养成分、谷胱甘肽、PSII的光保护能力和FRAP水平。与单独使用油菜素内酯相比,联合处理提高了芽苗菜的下胚轴长度、鲜重、谷胱甘肽含量、F/F值和抗氧化能力。玉米黄质和油菜素内酯的联合处理可以通过增加抗逆代谢产物的含量和减弱4℃贮藏的萝卜芽苗菜PSII的光抑制作用,使萝卜芽苗菜保持较高的生物量和抗氧化能力。
