Abstract
Pulsing with gibberellic acid followed by continuous sucrose treatment enhanced flower longevity and flower bud opening in cut Polianthes tuberosa L. cv. Double. Pulsing with gibberellic acid at 10 or 20 mg/L plus 8-hydroxyquinoline sulfate (200 mg/L) for 24 h followed by continuous sucrose treatments (4 or 8%) plus 8-hydroxyquinoline sulfate extended the vase life and significantly promoted flower bud opening as compared with the 8-hydroxyquinoline sulfate controls. A pulse with a higher concentration of gibberellic acid (50 mg/L) followed by sucrose solutions did not increase vase life or enhance flower bud opening greater than those pulsed with gibberellic acid at 10 or 20 mg/L followed by 8-hydroxyquinoline sulfate. A gibberellic acid (10, 20 or 50 mg/L) pulse followed by 8-hydroxyquinoline sulfate holding solution had little effect on longevity and flower bud opening in comparison to 8-hydroxyquinoline sulfate controls. Similarly, continuous sucrose treatment at 4 or 8% without a gibberellic acid-pulsed treatment also showed little effect on vase life and flower bud opening. Cut P. tuberosa treated with a gibberellic acid pulse followed by 8-hydroxyquinoline sulfate produced more ethylene than those treated with 8-hydroxyquinoline sulfate alone. Ethylene production from flowers pulsed with gibberellic acid followed by sucrose was low when compared with controls or those pulsed with gibberellic acid alone. Cut stems continuously placed in solutions containing sucrose produced less ethylene than those without sucrose. It is suggested that a gibberellic acid pulse at 10 mg/L followed by continuous sucrose treatment at 4% be recommended to growers for extending the vase life and enhancing flower bud opening in cut P. tuberosa.
