Duration of 1-Methylcyclopropene-Induced Responses on Volatile Production by 'GALA' Apple Fruit

The ethylene action inhibitor 1-methylcyclopropene (1-MCP) reduces the rate of ripening of climacteric fruit including apple. The longevity of 1-MCP responses induced by a single application at harvest is dependent in part on 1-MCP treatment concentration and post-application storage conditions. Ripening specific volatile production by apple fruit required continuous ethylene action, and fruit treated with 1-MCP exhibit reduce production of many volatile compounds. Experiments with ‘Gala’ apples were conducted over 3 production seasons to characterize the duration of 1-MCP responses of fruit stored in air or a controlled atmosphere (CA). After various storage durations, 1-MCP was reapplied at the same or higher concentrations, or the initial application rate was made. The increase in production of esters typical of normal ripening is delayed following 1-MCP treatment by 3-5 months. Apples treated with 1-MCP then stored in CA did not exhibit an increase in ester production at any point during storage. Increased production of aldehydes, particularly C8-10 compounds, occurred late in the storage period and was only partially inhibited by previous treatment with 1-MCP.
