The purpose of this study was to explore the effects of brassinolides(EBR)and methyl jasmonate(MeJA)on apple fruit quality during storage. The'Yuehua'apple fruit was used as a test material at different concentrations of EBR(0,0.02,0.05 mg · L-1)with MeJA(0,20,50 mg · L-1) mixed in pairs,and sprayed once on the fruit 30 days before harvest,and distilled water was sprayed as the control. The results showed that the mixed treatment of 20 mg · L-1 MeJA + 0.05 mg · L-1 EBR could delay the fruit firmness,titratable acid content,ascorbic acid content and soluble solids content increase of 'Yuehua'fruit during storage at room temperature,and prolong the fruit storage period. At the same time,the production of ethylene was 17.4% lower than that of the control,and the expression of ethylene synthesis genes MdACO1,MdACS1 and ethylene response factor MdERF3 were inhibited. 20 mg · L-1 MeJA + 0.05 mg · L-1 EBR treatment increased the color difference and anthocyanin content of the fruit by 7.3 and 1.4 times compared with the control,respectively,and increased the expression of MdMYB1,MdCHS,MdDFR and MdF3H in the peel. Moreover,50 mg · L-1 MeJA + 0.05 mg · L-1 EBR treatment group significantly increased the color difference and anthocyanin content of the fruit;however,the effect on other indicators was not significant. In summary,the treatment of 20 mg · L-1 MeJA + 0.05 mg · L-1 during apple fruit development had a significant promoting effect on the maintenance of internal quality and the improvement of appearance quality during fruit storage.
