Postharvest treatments designed to enhance the vase life of cut Gloriosa rothschildiana flowers were tested. Vase fife was significantly extended by the germicides 8-HQC (250 mg.liter-1), DICA (50 mg.liter-1), and Physan-20 (50 mg.liter-1). Germicides acted primarily by improving solution uptake. Sucrose, either as a continuous treatment (of 2% or 5% w/v), or as a 24-hour pulse (20%), significantly enhanced vase life, primarily by enhancing the development of immature buds and delaying senescence in open flowers. Flowers stored at 1C developed signs of chilling injury within 3 days, but chilling symptoms were not displayed in stems stored at 10C for 10 days. Flowers were not affected when exposed to 50 microliter ethylene/liter for 24 hours. Transport and short-term storage in sealed, air-filled bags to protect the flowers from physical damage resulted in some atmosphere modification within the bags. Fungal growth occurred when flowers were kept in air-filled bags for more than 6 days, resulting in a reduction in vase life.
