The application discloses a reagent, a method and application for reducing the astringency of grape fruits, wherein the reagent comprises strigolactone, brassinolide and melatonin. It is found that strigolactone can significantly reduce the astringency of grape fruits at a concentration of 1-3 μmol / L, with a maximum reduction of 50.59%, and does not affect the coloring of the fruits; low-concentration brassinolide (0.1-0.6 mg / L) can reduce the astringency while increasing the contents of total phenols and anthocyanins, and synergistically promote the coloring; and melatonin has astringency-reducing effect at a concentration of 5-50 μmol / L. Transcriptome analysis shows that strigolactone blocks tannin synthesis by inhibiting the expression of DFR and CCR genes, and brassinolide remodels the metabolic flow to the anthocyanin branch through BZR1. The application provides an efficient and safe technical means for the precise improvement of the flavor quality of table grapes.
