The plant hormone, ethylene, plays a major role in postharvest handling of fruits and vegetables by hastening ripening, senescence, abscission, and physiological disorders.

Abstract

The plant hormone, ethylene, plays a major role in postharvest handling of fruits and vegetables by hastening ripening, senescence, abscission, and physiological disorders. Technologies to limit ethylene biosynthesis, to efficiently remove it from storage rooms, and to inhibit its action are utilized widely in commercial practice. The determination of ethylene concentration is the first step for the optimization of handling, storage, and transportation. The inhibition of ethylene synthesis by reducing temperature, decreasing oxygen, and increasing carbon dioxide concentrations (controlled atmosphere), alone or in combination, are widely used approaches to delay postharvest senescence. The deciphering of ethylene’s perception has opened a new era by providing its antagonist 1-methylcyclopropene (1-MCP), currently used to counteract ethylene action in commercial storage facilities for a number of crops. New perspectives for better control of postharvest life are envisaged from a deeper understanding of the transcriptional and posttranscriptional molecular machinery of ethylene biosynthesis and action.
