研究了乙醇和蔗糖对月季切花瓶插寿命的影响。花被研究。试验于2004 - 2007年在两个受欢迎的品种“大嘎啦”和“第一红”上进行。3%（v/v）乙醇和3%（w/v）蔗糖的组合应用得到最长的瓶插寿命在两个品种。然而，蔗糖单独没有增加的花瓶寿命的大加拉。与对照相比，处理花的吸水速率更高，并且持续时间更长。花瓣脱落酸（阿坝）含量与花茎水势呈负相关。乙醇处理的花瓣中阿坝含量较低。阿坝浓度随花龄增加，而乙醇加蔗糖的组合治疗抑制这种增加，通过改善水分胁迫延长吸水和保持较高的花茎水势。乙醇加蔗糖处理也抑制乙烯的产生，这表明在延缓衰老的作用。
Summary The effect of ethanol and sucrose on the vase-life of cut rose (Rosa hybrida L.) flowers was studied. Experiments were conducted between 2004 – 2007 on two popular cultivars, ‘Grand Gala’ and ‘First Red’. The combined application of 3% (v/v) ethanol and 3% (w/v) sucrose gave the longest vase-life in both cultivars. However, sucrose alone did not increase the vase-life of ‘Grand Gala’. The rate of water uptake was higher in treated flowers, and lasted longer compared to controls. A negative relationship was observed between abscisic acid (ABA) concentrations in petals and flower stem water potential. The concentration of ABA in the petals of ethanol-treated flowers was low. ABA concentrations increased with flower age, while the combined treatment of ethanol plus sucrose inhibited this increase by ameliorating water stress by a prolonged water uptake and by maintaining a higher flower stem water potential. Ethanol plus sucrose treatment also suppressed ethylene production, suggesting a role in delaying ageing.
