Climacteric fruits continue to ripen postharvest, characterized by an increase in respiration and ethylene. Thus, the shelf-life, quality, and marketability of these fruits is reduced rapidly. One of the most important postharvest technology used to reduce the effect of exogenous and endogenous ethylene and extend the shelf-life of climacteric fruits is 1-methylcyclopropene (1-MCP). Currently, the application of 1-MCP on certain climacteric fruits is not commercially feasible due to the variable effects associated with this technology. In this review, factors that influence 1-MCP efficacy in climacteric fruits such as fruit maturity, concentration, genotypes, storage temperature and atmospheres, packaging material and application timing are critically discussed. In addition, current techniques used to mitigate the 1-MCP variability such as combined application with other postharvest treatments are briefly described and discussed. This review will provide an important information on the utilization of 1-MCP to prolong shelf-life in various climacteric fruits and help in the development of protocols for unregistered genotypes.
