ABSTRACT

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.

摘要

更年期的果实在收获后继续成熟，其特点是呼吸作用和乙烯增加。因此，这些水果的保质期、质量和适销性迅速降低。1-甲基环丙烯（1-MCP）是用于降低外源性和内源性乙烯影响并延长更年期水果保质期的最重要的采后技术之一。目前，由于与该技术相关的可变效应，1-MCP 在某些更年期水果上的应用在商业上是不可行的。在这篇综述中，对影响更年期水果中 1-MCP 功效的因素进行了批判性讨论，如水果成熟度、浓度、基因型、储存温度和大气、包装材料和应用时机。此外，简要描述和讨论了当前用于减轻 1-MCP 变异性的技术，例如与其他收获后处理的组合应用。本综述将提供有关利用 1-MCP 延长各种更年期水果保质期的重要信息，并有助于制定未注册基因型的方案。
