BACKGROUND Postharvest diseases result in major losses in fruits. Tomato is susceptible to postharvest rot caused by Botrytis cinerea and is regarded as a good model system to study postharvest disease and quality deterioration in fruit. To develop a safe and effective technique to alleviate disease and maintain fruit quality, the effects of methyl salicylate (MeSA) and 1‐methylcyclopropene (1‐MCP) either separately or combined on quality and gray mold caused by B. cinerea in tomato fruit were investigated. RESULTS The results showed that application of MeSA (0.05 mmol L −1 ) delayed fruit ripening and reduced gray mold. Compared with MeSA treatment, 1‐MCP (0.5 µL L −1 ) effectively delayed fruit ripening. Further, MeSA combined with 1‐MCP treatment was more effective in inhibiting fungal decay during storage than MeSA treatment alone. The combined treatment not only enhanced pathogenesis‐related protein 1 ( PR1 ) expression, activities of defense enzymes and total phenolic content but also inhibited the increase in electrical conductivity and malondialdehyde content. The combined treatment was also more effective in retaining firmness, color change and titratable acidity content than MeSA treatment alone. CONCLUSION MeSA combined with 1‐MCP treatment was a useful technique to maintain quality and alleviate gray mold in postharvest tomato fruit during storage. © 2018 Society of Chemical Industry
