EFFECT OF 1-MCP ON SENESCENCE OF DENDROBIUM FLOWERS IN SIMULATED SHIPMENT FOR EXPORT

S. Ketsa , N. Uthaichay
The effect of 1-methylcyclopopene (1-MCP) was investigated on the quality and vase life of Dendrobium ‘Jacky’ inflorescences during simulated shipment. Cut Dendrobium ‘Jacky’ inflorescences with wet-packing were treated with 300 or 500 nl L-1 1-MCP at 25°C for 4 h and held in cardboard boxes at 25°C for 3 days for simulation of air transportation. Upon unpacking the flowers were individually held in 15 ml centrifuge tubes containing distilled water at 25°C. The 1-MCP treatment showed less flower abscission and less wilting of open flowers and flower buds. The 1-MCP treatment also reduced the ethylene concentration inside the boxes. It is concluded that a pretreatment with 1-MCP can be commercially applied for export of orchid flowers.
