Abstract: Ethylene regulates many aspects of plant growth and development. During the post-harvest handling of ornamental plants, ethylene presence must be minimized to prevent quality decrease of post-harvest life, such as petal abscission and leaf senescence. To minimize the ethylene effect, several prevention strategies were developed, such as inhibition of ethylene biosynthesis and ethylene perception. This review described the inhibition of ethylene perception through chemical compounds application. Inhibition of ethylene perception is a more effective technique compared to ethylene biosynthesis in preventing ethylene effect. This was due to both endogenous and exogenous ethylene can be blocked. 1-Methylcyclopropene (MCP) is one of the common chemical compound used as ethylene inhibitor. Two formulations of 1-MCP had been developed in the recent years, gas-released powder (volatile 1-MCP) and water-soluble powder (sprayable 1-MCP). Despite having the same active ingredient, the two formulations had different affinity in ethylene effect prevention. The effectiveness of 1-MCP had been widely investigated on several ornamental plants such as Chrysanthemum, Pelargonium, Kalanchoe, Grevillea. Recently, 1-MCP had been used to improve other plants such as and Phalaenopsis, Curcuma and Ginger.
