用0 ~ 40%的蔗糖溶液处理菊花的切花芽。在100 ft-c荧光灯（24小时）、相对湿度40至70%、温度19至21°C的室内条件下，“信天翁”、“弗雷德鞋匠”、“流光”和“明亮的金色安妮”的浓度分别为2%、5%、20%和30%。蔗糖比葡萄糖好;甘露醇有毒。银硝酸盐（25 ppm）和柠檬酸（75 ppm）导致最佳质量的花而没有叶损伤; 200 ppm 8-羟基喹啉柠檬酸盐导致叶损伤。直径大于5.0厘米、重10克的芽在蔗糖溶液中最易开放。花在溶液中开放7-9天，质量更好，比温室中的植物上开放的花寿命更长。
Cut flower buds of chrysanthemums were opened in sucrose solutions from 0 to 40%. Concentrations of 2% for ‘Albatross ’, 5% for ‘Fred Shoesmith’, 20% for ‘Streamer’ and 30% for ‘Bright Golden Anne’ were optimal under room conditions of 100 ft-c fluorescent light (24 hr); relative humidity, 40 to 70%; temp 19 to 21°C. Sucrose was better than glucose; manitol was toxic. Silver nitrate (25 ppm) and citric acid (75 ppm) resulted in best quality flowers without leaf injury; 200 ppm 8-hydroxyquinoline citrate caused leaf damage. Buds larger than 5.0 cm diam and 10 g fr wt were best for opening in sucrose solutions. Flowers opened in solution in 7-9 days and were better quality and had greater longevity than those opened on the plant in the greenhouse.
