Abstract: Strelitzia reginae cut flowers were treated with 2 μL·L^-1 of 1-MCP at different temperature for different fumigation duration and fumigation times during storage to investigate the changes of physiological indexes. The results indicated that both ambient temperature （25 ℃）and cold temperature （12 ℃）were suit for storing Strelitzia reginae cut flowers,while the effects of the treatment in cold temperature were superior than that in ambient temperature. After fumigation for 6 h or 24 h at both temperatures,the production of ethylene was inhibited significantly,preservating freshness rate was enhanced and open-rate of cut flowers were promoted,yet fumigation for 6 h was more suitable for preservation; The second fumigation was unnecessary for Strelitzia reginae cut flowers. So,fumigation for 6 h at cold temperature was the best condition for the storing of Strelitzia reginae cut flowers. However,the more economical,effective and simple mode was fumigation for 6 h at ambient temperature.
