Abstract

Experiments were carried out to investigate the effects of different types and concentration of sugars and aminooxyacetic acid (AOA) and their combination in extending the vase-life of pollinated Dendrobium Pompadour flowers. The results obtained showed that the most effective treatments in extending the vase-life of pollinated Dendrobium Pompadour flowers and delaying the post-pollination symptoms were 0.05 mM AOA and the treatment which combined 0.05 mM AOA with 4 glucose. Both treatments showed a vase-life of up to 13 days, about 6 folds more than that of the control. Furthermore positive effects were also observed in a delay of weight loss, improved water uptake, change in petal thickness and colour. A combination of 0.05 mM AOA and 2 sucrose extended the vase-life of flowers up to 5 days. Inclusion of 4 glucose and 2 sucrose alone only prolonged the vase-life of flowers two days more compared to that of the control. Holding solutions containing sugars alone only prolonged the vase-life of flowers for just two days more compared to control. As has been studied in other experiments, pH of the holding solutions containing sugars alone maintained values of 5.0-7.0 while those with AOA and a combination of AOA and sugar at 3.0-5.0. Aminooxyacetic acid (AOA) and its combination with glucose extended the vase-life of pollinated Dendrobium Pompadour and also delayed the post-pollination symptoms.
