| Abstract:
The role of open florets in flower bud opening of Dendrobium Asuka White, Dendrobium Jew Yuay Tew, Dendrobium Madame Vipa, Dendrobium Mary Mak, Dendrobium Pompadour and Dendrobium Youppadeewan held in the solution containing 225 mg 1-1 8-hydroxyquinoline sulfate, 30 mg 1-1 AgNO3 and 4 % glucose was studied at ambient temperature. The results showed that inflorescences with removal of total open florets had the least flower bud opening and followed by removal of two and third of total open florets, respectively. Bagging of open florets also reduced flower bud opening but was less effective than removal of open florets. Inflorescences bearing with both open florets and flower buds had higher rates of water uptake than those with removal and bagging of open florets. The role of open florets in maximizing flower bud opening of Dendrobium was discussed. | |
