摘　　要：研究鹤望兰鲜切花在2μL.L-1新型乙烯抑制剂1-甲基环丙烯(1-MCP)熏蒸处理下,不同贮运温度、熏蒸时间和重复熏蒸与否对鹤望兰贮运期间生理代谢指标(切花失水率、乙烯释放量、花瓣细胞膜透性、花瓣花青素、次花的开放率和保鲜率)的影响。结果表明:在常温(25℃)和冷藏(12℃)条件下均适合鹤望兰鲜切花贮运,但冷藏贮运(12℃)保鲜效果较好。2种贮运温度下6h和24h熏蒸处理均能极显著地抑制乙烯的释放,提高切花的保鲜率,促进次花的开放,其中,6h熏蒸处理保鲜效果较好。鹤望兰切花不需要重复熏蒸处理。因此,2μL.L-11-MCP对鹤望兰鲜切花贮运保鲜的最佳熏蒸模式为冷藏贮运(12℃)下6h熏蒸处理。而常温(25℃)贮运下6h熏蒸处理是经济、有效、方便的模式。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.
