1-Methylcyclopropene (1-MCP) is a cyclopropene derivative used as a synthetic plant growth regulator. It is structurally related to the natural plant hormone ethylene and it is used commercially to slow down the ripening of fruit and to help maintain the freshness of cut flowers. 1G 1-MCP (4.0% Cyclodextrin complex) can be used in 16-20 CBM warehouse.

Mechanism of action

Ethylene exists as a gas and it acts at trace levels throughout the life of a plant by stimulating or regulating various processes such as the ripening of climacteric fruit, the opening of flowers, and the shedding of leaves. The mechanism of action of 1-MCP involves its tightly binding to the ethylene receptor in plants, thereby blocking the effects of ethylene.

How to use
There are two principal commercial uses of 1-MCP: maintaining the freshness of ornamental plants and flowers, and preventing the ripening of fruits. 1-MCP is combined with cyclodextrin for handling and then mixed with a specific amount of water to release it into the air. It is used in enclosed indoor sites, such as coolers, truck trailers, greenhouses, storage facilities, and shipping containers.
The use of 1-MCP in agricultural products including apples, kiwifruit, tomatoes, bananas, plums, persimmons, avocados and melons.
1-MCP is also being developed as a new crop protection technique. By spraying 1-MCP on growing field crops during times of stress, the crops may be protected from moderate heat and drought conditions.

General procedure
Set the fruits in a confined space, dissolve 1-MCP in water in a cup (1g 1-MCP / 30mL water), and put the cup in the sealed store to fumigation in an appropriate time (0-13℃ for 24-36 hours; 10-25℃ for 12-24 hours, in case of storage at temperatures below zero,1-MCP may not be used.). The concentration of 1-MCP in air of 1ppm can reach a good effect. 

1. The key point for use of 1-MCP is that the fruits should be treated quickly after harvesting. (1-7 days after harvesting is preferred)
2. The fruits should be kept dry before treated. 
3. Prior to treatment, the ventilation should be made to exhaust surplus carbondioxide; after treatment, the temperature decrease should be made slowly.
