The postharvest life of various ornamental species and cultivars in vases of water was evaluated twice a week from harvest. The cut plant material was held in an enclosed area under ambient conditions (around 25 deg C and 50% RH); the vase water was changed weekly and no additives or preservatives were used. Simple mathematical regression models were fitted to the vase-life data. Linear models best described loss of quality in Banksia species. Fractional exponent models were best for Alpinia purpurata, and foliage of Lycopodium cernuum, Strelitzia reginae and Cordyline terminalis, Arundina graminifolia. Exponent models were best for Anthurium andraeanum cultivars, Leucadendron and Leucospermum species and hybrids; and logarithmic-fractional exponent models for Heliconia psittacorum cultivars. Validation tests verified the predictability of the vase life models for the flowers of H. psittacorum cultivars, Alpinia purpurata and Anthurium andraeanum cv. Midori and the foliage of Lycopodium cernuumand Arundina graminifolia. The pattern of loss of quality provides the necessary basis to develop vase life criteria for different species and to determine schedules for shipping by growers and marketing by wholesalers and retailers.
