Résumé

Citrus fruits are nonclimacteric and produce only low amounts of ethylene. However, exogenous applied, and possibly endogenous ethylene, may be involved in the regulation of fruit maturation and senescence. The authors examined the effects of ethylene and 1-methylcyclopropene (1-MCP), an ethylene action inhibitor, on the postharvest qualities of "Shamouti" (Citrus sinensis L. Osbeck) oranges. Neither ethylene nor 1-MCP had any effects on the loss of fruit weight and firmness. Action of ethylene on postharvest transformations of the fruit and on chilling injury symptoms are studied. According to these effects, the authors suggest that 1-MCP may be applied as a postharvest treatment to inhibit the degreening process in citrus fruits which are preferably marketed green, but special care must be taken to avoid chilling injury and decay development.
