Abstract
The market life of many fruits and vegetables can be extended through storage at lowtemperatures. Chilling injury (CI) is one of the major postharvest storage problems for tropicalcommodities. Storing these products at temperatures below their critical temperature may result insevere physiological disorders known as CI symptoms. Mangoes (Mangifera indica) are susceptible to CI when stored below 12C. Visual CI symptoms include uneven ripening, surface pitting,discoloration, shriveling, and scald. The appearance of these symptoms decreases market value.Many researchers have conducted studies to overcome these serious problems. Among the varioustechniques developed, postharvest treatment with methyl jasmonate (MJ) or diphenylamine (DPA)has been efficient in reducing the incidence of CI symptoms in fruits and vegetables. This study aims at assessing and comparing the potential of MJ and DPA to reduce CI symptoms inmangoes (cv. Tommy Atkin) stored at temperatures between 1 and 10C. Laboratory scaleexperiments were carried out on mangoes that were either dipped in MJ solution (10-4M), or in12mM DPA solution, or left untreated (control). The mangoes were stored at 1, 4, 7 and 10C for 18days. Then, the fruits were allowed to ripen at 20C for four days. Fruit quality was assessed andcompared after storage and after ripening. Both MJ and DPA treatment had the ability to reduce theCI symptoms in mango fruits stored at low temperatures. Decay was reduced during subsequentripening. MJ treated fruits had lower mass loss, brighter colored skin, and higher total soluble solids(TSS) than the control treatment. The overall quality of MJ and DPA treated fruits was good with lesssurface pitting and scalding compared to the control treatment. The best results were obtained atstorage temperatures of 7 and 10C. Both MJ and DPA postharvest treatment have the ability toreduce CI symptoms in mangoes cv. Tommy Atkins.
