Resumo: | This work had the goal to evaluate the influence of temperature and dry storage on the postharvest longevity of Epidendrum ibaguense flowers previously treated with silver thiosulfate (STS). The flowers were harvested and pulsed for 30 minutes with 2 mM STS. Then both, the STS treated and untreated flowers were packed in perforated low density polyethylene bags, packed in cardboard boxes and stored at 5 and 10°C, where they remained for four and eight days. After this period, the flowers were kept in vase with distilled water at 25ºC, and analyzed at every 24 h. The experiment was arranged in a complete random design 2 x 2 x 2 factorial scheme, with four replicates, containing four inflorescences each, except for the determination of transpiration and water rates uptake, composed by sixteen replicates of one stem. The vase life of the flowers of the E. ibaguense was increased to 6.5 days when pulsed with 2 mM STS for 30 minutes, followed by storage at 10ºC for a maximum period of four days. The STS applied before the cold storage reduced the rate of flower abscission and improved the ratio between the transpiration and water uptake.
