ââ?¬Ë?Maha Chanokââ?¬â?¢ mango is an economic fruit crop widely cultivated commercially throughout Thailand. By nature,\nmango fruit has a rather limited storage life after harvest. 1-methylcyclopropene (1-MCP) has been accepted as a\ncommercial substance to improve several fruit qualities. The objective of this research was to study the effects of\n1-MCP on the external postharvest qualities and storage life on the ââ?¬Ë?Maha Chanokââ?¬â?¢ mango fruit. The experiment\nwas laid out in a Completely Randomized Design with three replicates, ten fruits per replicate. Mango fruit was\nfumigated with 1-MCP at three concentrations (1000, 1250, or 1500 nl l-1) and three fumigation periods (12, 18,\nor 24 h), compared with the control fruit. After treating, all treatments were stored under ambient temperature\n(27 C, 80%R.H.). The following determinations were made every two days for assessment of fruit weight loss,\nfirmness, chlorophyll content, decay incidence, and storage life. The results showed that fruit treated with 1500\nnl l-1 1-MCP for 24 h had the maximal fruit firmness. For chlorophyll content, the results showed that\nfruit-treated with 1500 nl l-1 1-MCP for 12 h could effectively retain the highest chlorophyll contents.\nFurthermore, both the lowest fruit decay and the longest storage life of 12 days were achieved from the fruit\ntreated with 1000 nl l-1 1-MCP for 12 h.
