The vase life of anthurium (Anthurium andraeanum), Heliconia (Heliconia psittacorum cv. `Andromeda', H. chartacea cv. `Sexy Pink'), red and pink ginger inflorescence (Alpinia purpurata) was increased by benzyladenine (BA, 100 mg L-1), applied as a dip or as a spray. There was no effect of BA on the vase life of Bird of Paradise (Strelitzia reginae), Beehive ginger (Zingiber spectabilis), and Uluhe fern curls (Dicranopteris linearis). Different anthurium cultivars showed differences vase life response to BA treatment from a 20% reduction to a 2.5 fold increase in vase life. Anthurium cultivars that responded positively to BA and were packed for 8 days had 20 days longer vase life than non-BA treated flowers. The effects of BA on topical foliage varied, while the vase life of anthurium leaves was extended by BA and that of the flowerless Bamboo orchid (Arundina bambusifolia) and the fern Lycopodium (Lycopodium cernuum) leaves were shortened. The data suggested that the effect of BA on the extension of vase life depended upon flower or inflorescence type, season of harvest and cultivar.
