Ethylene production ripening and storage performance of plum fruit (Prunus domestica L.) treated in preharvest with ethephon and 1-MCP prior to storage

During the last 3 weeks of plum fruit ripening o­n the tree, softening progressed gradually.Spraying trees with ethephon twice, two weeks apart, within this period o­nly slightly accelerated fruit softening o­n the tree, but it affected their postharvest softening during storage at –0.5°C.The earlier spraying was not as effective as the later o­ne.In addition, softening of plums treated o­n the tree with ethephon was considerably faster than untreated o­nes during shelf life period at room temperature especially after longer storage at –0.5°C.1-MCP treatment of plums before placing them into storage room inhibited softening, particularly those treated preharvest with ethephon.Firmness of ‘Cacanska Najbolia’ plums not treated with ethephon remained almost unchanged during 8 weeks storage at –0.5°C and application of 1-MCP did not improve their storage performance.From all plum cultivars grown in Poland this o­ne possess the highest storage potential at –0.5°C.However, when these plums are stored at 3-4°C the internal breakdown development had commenced by the fourth week of storage.
