Popis: The present work was carried out to evaluate the influence of temperature and wet-versus-dry storage on longevity, respiration and ethylene production during storage of E. ibaguense flowers. The inflorescences were harvested and stored at 5, 10, 15, 20, 25, 30, 35, and 40°C, in water or dry, until complete senescence. Respiration increased when inflorescences were treated with wet or dry storage. The Q10 factor for this flower, at temperatures ranging from 5 to 40°C, was similar to most fresh horticultural products, varying between 1.2 and 3.31 depending on storage temperature. Production of ethylene by the inflorescence was maximal at 20°C for flowers maintained in water, and at 35°C for those flowers kept dry, followed by a sharp drop in both treatments. A maximal shelf life for cut flowers was obtained when the inflorescences were stored wet at 10°C. Symptoms of chilling were observed in flowers stored in water after six to seven days at 5°C, showing petal wilting and necrosis of the labellum. At 40°C, flowers stored dry showed severe petal wilting and darkening of bud petals less than one day after harvest.
