In order to provide a scientific and rational theoretical basis for the use of Compound Sodium Nitrophenolate in the production of mango, the effects of Compound Sodium Nitrophenolate in the pre-harvest application on fruit quality and incidence of postharvest desease of Guifei mango were explored Mango cultivar ‘Guifei’ was selected as the material. Compound Sodium Nnitrophenolate with the concentration of 500 mg/L was sprayed every 9-12 days for the first time on the 15th day after the full bloom period, and 6 times in total. Longitudinal and transverse diameters during the fruit development were measured, and the single fruit weight was determined at maturity. Color parameters (L, a, b values) of the peel during the ripening process, the hardness of the fruit pulp, the content of the soluble solids, the total acid content and the incidence of diseases were also investigated. The experimental results showed that spraying compound sodium nitrophenolate before harvesting could promote fruit enlargement, significantly increase the weight of single fruit at maturity, enhance post-harvest pigmentation, and delay the decrease of pulp hardness and the increase of soluble solids content. The total acid contents remained basically unchanged, but greatly reduced the post-harvest disease incidence and disease index.

Key words: mango fruit (Mangifera indica L.), compound sodium nitrophenolate, development of fruit, fruit quality, disease
