TL;DR: In this article, a review of the use of 1-methylcyclopropene (1-MCP) as an inhibitor of ethylene action is presented, which is a tool that can help scientists make major advances in understanding the role of the chemical in plants.

TL;DR: Since 1-MCP apparently is non-toxic at concentrations that are active, it may in future be available for regulating the ripening of fruits and preventing the deleterious effects of ethylene in vegetables.
Abstract: A number of organic molecules that appear to block the ethylene receptor have been discovered recently. For example, on irradiation with visible light, diazocyclopentadiene (DACP), gives rise to some potent but as yet unidentified inhibitor compounds. Some synthetic cyclopropenes have been shown to bind to the ethylene receptor and prevent the physiological action of ethylene for extended periods. Cyclopropene (CP), 1-methylcyclopropene (1-MCP) and 3,3-dimethylcyclopropene (3,3-DMCP) have been shown to prevent ethylene effects in a number of plants. As low a concentration as 0.5 nl l -1 of 1-MCP is sufficient to protect carnation (Dianthus caryophyllus) flowers for several days against ethylene, and 0.7 nl l -1 1-MCP or CP will prevent the ripening of banana (Musa sapientum) for 12 days at 24°C. Some plant organs require higher concentrations of these inhibitors. Complete inhibition of ethylene effects in pea seedlings requires treatment with 40 nl 1 -1 of 1-MCP. These novel inhibitors appear to be suitable for many commercial applications including extending the vase life of cut flowers and the display life of potted plants. Since 1-MCP apparently is non-toxic at concentrations that are active, it may in future be available for regulating the ripening of fruits and preventing the deleterious effects of ethylene in vegetables.

TL;DR: In this paper, the authors used 1-methylcyclopropene (1-MCP) at a preclimacteric stage and at intervals of 6, 12 and 24 hours after propylene treatment (HAPT) to initiate ripening.

TL;DR: In this article, an ethylene action inhibitor, 1-methylcyclopropene (MCP), was applied to preclimacteric and climacteric apple (Malus sylvestris L. (Mill.) var. Mansf.) fruit.
Abstract: ADDITIONAL INDEX WORDS. fruit quality, firmness, ethylene, Malus sylvestris var. domestica, postharvest physiology, storage ABSTRACT. An ethylene action inhibitor, MCP, was applied to preclimacteric and climacteric apple ( Malus sylvestris L. (Mill.) var. domestica Borkh. Mansf.) fruit. Experiments were conducted in North Carolina and Washington State utilizing the following cultivars: Fuji, Gala, Ginger Gold, Jonagold, and Delicious. MCP inhibited loss of fruit firmness and titratable acidity when fruit were held in storage at 0 °C up to 6 months and when fruit were held at 20 to 24 °C for up to 60 days. For all cultivars except 'Fuji', differences in firmness between treated and nontreated fruit exceeded 10 N after 6 months storage. These beneficial effects were seen in both preclimacteric and climacteric fruit. Ethylene production and respiration were reduced substantially by MCP treatment. MCP-treated fruit had soluble solids equal to or greater than those in nontreated fruit. Storage and shelf life were extended for all cultivars tested. Chemical name used: 1-methylcyclopropene (MCP).
