The vase life of cut flowers is the most important factor affecting the market value popularity of hydrangeas as cut flowers has increased steadily in recent years. However, the vase life of cut hydrangea flowers is short depends on wilting and sepal browning. In this study SUA (succinic acid) (50 mg L-1 and 100 mg L-1), GA (glycolic acid) (38 mg L-1 and 76 mg L-1, BC (benzethonium chloride) (25 mg L-1), CA (citric acid) (100 mg L-1) and 8-HQS (8-hydroxyquinoline sulfate) (250 mg L-1) were used to determine the effects on vase life of cut hydrangea flowers (Hydrangea macrophylla 'Ankong Rose'). Distilled water was used as the control. Vase life, relative fresh weight, daily and total solution uptake were measured. The experiment was a completely randomized design with ten replications and there was one flower in each replication. The longest vase life of hydrangea flowers was 12,10 days with 8-HQS (250 mg L-1), followed by 76 mg L-1 of GA (10.70 days) and 38 mg L-1 of GA (9.70 days). 8-HQS significantly increased the vase life of hydrangeas and also determined that same treatment increased the total solution uptake and delayed relative fresh weight loss. These results indicated that 8-HQS can be used to prolong the vase life of cut hydrangea flowers.
