Characteristics of ethylene production of Dendrobium orchid flowers.

 

Intact flower buds of Dendrobium cultivars Caesar 2N, Pompadour, Sabin, Sonia Bom #28, Walter Oumae Taba 2N and Walter Oumae Taba 4N produced greater amounts of ethylene than intact open florets. Similarly, ethylene production and 1-aminocyclo-propane-1-carboxylic acid content of isolated flower buds were higher than those of isolated open florets. The ability to convert ACC to ethylene in isolated flower buds, half open and open florets was comparable. In isolated open florets held in solutions containing ethylene inhibitors (aminooxyacetic acid, CoCl2 or AgNO3) at concentrations of 0.25, 0.50 and 1.00 mM ethylene production was not reduced, while vase life was shortened. The vase life of open florets was significantly increased when they were held in a solution containing 8-hydroxyquinoline sulfate (HQS) + glucose and even more effectively when aminooxy-acetic acid was included together with HQS + glucose but the ethylene production was not reduced compared with those held in distilled water.
