Abstract:
The longevity of cut Phalaenopsis (Phalaenopsis hybrid, cv. Herbet Hager) flowers is normally 2 to 3 weeks. After pollination however, there was a rapid acceleration of the wilting process, beginning after only 24 h. Enhancement of senescence in several Phalaenopsis cultivars as well as in Doritaenopsis, Dendrobium and Cymbidium, was induced by successful pollination and only slightly or not at all by emasculation. Wilting of the flowers was accompanied by a loss of water from cells of the upper layer of the petals, leading to their upward folding. Following pollination there was an increase in ethylene production and sensitivity to ethylene. The increase in ethylene production began about 10 h after pollination and reached its peak after 30 h. An obvious increase in sensitivity to ethylene could already be detected 4 h after pollination and reached its peak 10 h after pollination. The increase en ethylene sensitivity following pollination was not dependent on endogenous ethylene production as it occurred also in flowers treated with (aminooxy)acetic acid, an inhibitor of ethylene biosynthesis. © 1994 Kluwer Academic Publishers.
