Keyword:  1-甲基环丙烯(1-MCP)月季切花保鲜;
Abstract: 以四大切花之一的月季玫瑰红品种为试材,研究了1-甲基环丙烯(1-MCP)对月季切花保鲜进程中各生理因子的影响.结果表明,浓度为500mg/kg、800mg/kg和900mg/kg的1-甲基环丙烯在常温下处理月季切花4h,能延长常温瓶插务件下月季切花的可观赏时间,延缓月季切花中过氧化物酶活性峰值的出现,并使瓶插期间花瓣的含糖量升高,月季切花吸水量得到提高,从而延缓了月季切花出现的弯茎和蓝变现象.同时经仪器测量,这一处理使月季切花的花茎和花重变化速率明显降低.试验以800mg/kg处理效果最佳,其瓶插寿命最长,达到11d,花重最大达16g以上,含糖量最高达3%,过氧化物酶活性峰值的出现也被延缓.
