Allium is a genus of monocotyledonous flowering plants. The Allium genus is one of the most popular ornamental plants in the world. Most cut flowers purchased in Korean markets are not native and are dependent on imports. This experiment was conducted to improve the flower quality and vase life of Allium taquetii that was native in Korea. The flowers were harvested as ½ opened florets and the scapes were shortened to the same length. Cut flowers were treated with 25, 50 and 100 mg L‑1 of gibberellic acid (GA3); 25, 50, and 100 mg L‑1 of 8-hydroxyquinoline sulfate (8-HQS); 0.1, 0.3 and 0.5 mM of silverthiosulfate (STS); Chrysal, and Floralife. Cut flowers treated with sterile water were used as the control group. The vase life and fresh weight data were recorded. GA3 was significantly effective at all concentrations and the florescence was delayed in high concentrations. The relative fresh weight of flowers treated with 100 mg L‑1 GA3 was significantly higher than that of the control. STS and 8-HQS had negative effects in high concentrations, while there were no significant effects in 0.1 mM STS and 25 mg L‑1 8-HQS. The vase life of flowers under Chrysal and Floralife treatments was shorter than that of the control. This study indicated that GA3 holding solution treatment can be applied to extend the postharvest life of cut Allium.
