The effect of gibberellic acid (GA₃) and benzyladenine (BA) on the postharvest quality and vase life of gerbera cut-flowers was investigated. Freshly cut flower stems of gerbera cultivar 'Good Timing', with four outer disc florets open, were put in vases containing 0, 50, 100, 150, 200, or 300 mgㆍL-¹ GA₃ and 0, 10, 25, 50, 100, or 150 mgㆍL-¹ of BA for 48 hr and then held in vases containing 2.5% ethanol and 3% sucrose. Vases were placed in chambers at 25℃ with a relative humidity about 70% and were arranged in a Completely Randomized Design with three replicates. Data were recorded for vase life, fresh weight, solution uptake, membrane stability, total soluble solid over time and analyzed statistically. GA₃ 50 mgㆍL-¹ and BA 50 mgㆍL-¹ were the most effective treatments on vase life, fresh weight, solution uptake, membrane stability and total soluble solids of gerbera cut flowers. Cytokinins and gibberelins have potential to enhance post harvest quality of cut gerbera flowers.
