Abstract
This study was conducted to investigate the detrimental effects of decapping and emasculation on the postharvest quality and the vase life of cut Cymbidium flowers with or without 1-Methylcyclopropene (1-MCP) and Aminoethoxyvinylglycine (AVG) treatments. The vase life treated by 1-MCP 150 ppb for four hours regardless of decapping or emasculation was significantly prolonged 12 days more. Ethylene production in the treatment without 1-MCP began to be raised from 7days, 1-MCP treatments, regardless of the concentration of processing did not occur until 15days. Ethylene began to production when the lip began to coloration. Compared to the 1-MCP effect, the AVG treatment of 0.5 and 1mM for four hours prolonged the vase life about nine days more. Whereas, the only decapping or emasculation treatments were effective to more three days longer in the vase life of cut Cymbidium' Halleluiah' flowers. 1-MCP treatment was very beneficial for Cymbidium 'Halleluiah' cut flowers than AVG.
