Fresh figs are a very attractive commodity, but providing consumers with high quality fig fruit is a challenge. Fruit harvested too ripe has an extremely short postharvest life due to ethylene-induced over ripening, expressed as excessive softening, tissue maceration and exudation of syrupy liquid from the ostiole. The inhibitor of ethylene action 1-methylcyclopropene (1-MCP) has been used successfully in various plant species to arrest the plant's response to elevated internal ethylene level. It has also been used in figs as a postharvest treatment, but it only partly slowed the ripening. We examined the effects of preharvest application of 1-MCP on 'Brown Turkey' fig fruit development on the tree and in storage. Right after treatment, ethylene production rate of 1-MCP-exposed fruit was six times that of the non-treated figs, but development of the treated fruit was delayed. At harvest, most of the figs in the 1-MCP-treated group were at commercial harvest maturity, while many of the control fruits had reached full ripening. During storage, senescence and spoilage of the 1-MCP-treated figs were slower and lower than in controls, as manifested by fruit color, firmness, internal texture, weight, size, shriveling, and decay. Thus 1-MCP applied on fig trees at the fig's pre-climacteric stage can delay the senescence of 'Brown Turkey' figs and improve their storage and transportation potential. © 2012 Elsevier B.V.
