Floral senescence or petal abscission that determine cut flower quality and longevity are primarily caused by the regulation of endogenous ethylene and perception of endogenous and exogenous ethylene in floral organs (such as the petals and gynoecium), in ethylene-sensitive species. Several attempts have been made to prolong flower quality and longevity using silver ions and other chemicals that inhibit ethylene production and perception in floral organs. Among the available compounds, 1-methylcyclopropene (1-MCP) has been increasingly used as ethylene-action/perception inhibitor because of its ability to inhibit ethylene action/perception and it is environmentally safe. Although 1-MCP has been used in several cut flower crops for about 25 years, there has been no review yet that critically emphasizes the benefits or difficulties of using this compound for the prolongation of cut flower quality and longevity. Here, we outline the role of 1-MCP in inhibiting ethylene action/perception and petal senescence in cut flowers through the blocking of receptor binding sites, and we discuss how various factors affecting efficacy of 1-MCP (such as concentration, treatment time and temperature, genotype, and flower stage) are involved in the achievement of flower longevity. Moreover, we highlight the advantages of applying nonvolatile and liquid 1-MCP formulation types, as opposed to using the conventional 1-MCP treatment (powder formulation type). We expect that this review will provide useful information for the future utilization of 1-MCP for the maintenance of cut flower longevity.

在乙烯敏感物种中，决定切花质量和寿命的花衰老或花瓣脱落主要是由内源乙烯的调节和花器官（如花瓣和雌蕊）中内源和外源乙烯的感知引起的。已经进行了一些尝试，以使用银离子和其他抑制花器官中乙烯产生和感知的化学物质来延长花的质量和寿命。在可用的化合物中，1-甲基环丙烯 (1-MCP) 越来越多地用作乙烯作用/感知抑制剂，因为它能够抑制乙烯作用/感知，并且对环境安全。尽管 1-MCP 已在多种切花作物中使用约 25 年，目前还没有评论批判性地强调使用这种化合物来延长切花质量和寿命的好处或困难。在这里，我们概述了 1-MCP 通过阻断受体结合位点抑制切花乙烯作用/感知和花瓣衰老的作用，并讨论了影响 1-MCP 功效的各种因素（如浓度、处理时间和温度、基因型和花期）与花寿命的实现有关。此外，我们强调了应用非挥发性和液体 1-MCP 制剂类型的优势，而不是使用传统的 1-MCP 处理（粉末制剂类型）。我们希望这篇综述能为未来利用 1-MCP 维持切花寿命提供有用的信息。
