Abstract
The experiment was conducted to find out the role of methyl jasmonate and elevated carbon dioxide on postharvest chilling susceptibility and the effective treatment on inhibition of chilling injury (CI) and preservation of quality in cucumber (Cucumis sativus. L. cv. Chuycheong). CI symptoms started developing in pericarp from the 4-5th days of storage at 4C, CI was intensified after cucumber were transferred to room temperature. CI was inhibited by 0.01mM methyl jasmonate and 5% CO_2 treatments during storage or after being transferred to room temperature. Cucumber stored at 12C and 20C showed accelerated senescence and wilting although any CI symptoms were not appeared. Respiration rate and ethylene production in cucumber stored at 4C increased significantly after fruits were transferred to room temperature, they were lower in cucumber stored at 4C than 12C or 20C. There was no remarkable increase of gas production in cucumber stored at 12C or 20C after being transferred to room temperature. But weight loss was higher in cucumber stored at 12C or 20C than 4C, pericarp wilting and stem drying caused serious loss of market quality. Gas production and weight loss were inhibited by 0.01mM methyl jasmonate and 5% CO_2 treatment at 4C during storage or after cucumber were transferred to room temperature. These treatments were also effective on maintenance of firmness and color, therefore they were considered as positive treatments for inhibition of CI and preservation of quality in future.
