研究了蔗糖连续处理对金鱼草切花开放、瓶插寿命、碳水化合物含量和乙烯释放的影响。CV.黄蝴蝶）花进行了调查。25、50、75、100 g·L-1蔗糖和200 mg·L-1 8-羟基喹啉硫酸盐连续处理显著促进小花开放，延长花穗瓶插寿命。最有效的蔗糖浓度为50 g·L-1，因此该浓度用于以下实验。这种处理抑制了小花鲜重的下降。花瓣中检测到葡萄糖、果糖、蔗糖和甘露醇。葡萄糖，果糖和蔗糖浓度的花瓣控制穗下降后一天收获，并保持在低水平，但蔗糖处理抑制这些糖的减少。无论蔗糖处理，甘露醇浓度逐渐下降。蔗糖处理延迟了跃变型乙烯的产生，这表明蔗糖促进花蕾开放和抑制花衰老的作用是通过增加糖浓度和抑制乙烯合成来实现的。
Effects of continuous treatment with sucrose on floret opening, vase life, carbohydrate concentrations, and ethylene production in cut snapdragon (Antirrhinum majus L. cv. Yellow Butterfly) flowers were investigated. Continuous treatment with sucrose at 25, 50, 75, or 100 g·liter-1 in combination with 200 mg·liter-1 8-hydroxyquinoline sulfate markedly promoted floret opening and extended the vase life of flower spikes. The most effective sucrose concentration was 50 g·liter-1 so that this concentration was used for the following experiments. This treatment suppressed the decrease in fresh weight of florets. Glucose, fructose, sucrose, and mannitol were detected in petals. Glucose, fructose, and sucrose concentrations of petals in control spikes decreased one day after the harvest and remained at low levels but the sucrose treatment suppressed the decrease in these sugars. Regardless of the sucrose treatment, mannitol concentration gradually decreased. The onset of climacteric ethylene production was delayed by the sucrose treatment which suggests that the effects of sucrose for promoting bud opening and inhibiting flower senescence is attributed to an increase in sugar concentrations and the inhibition of ethylene synthesis.
