Effect of ethylene and pulsing solutions on longevity of Canadian Goldenrod stems

Two experiments were performed to evaluate the sensitivity to ethylene and the effect of pulsing solutions on postharvest longevity of Canadian goldenrod stems. The first experiment consisted of ethylene application in the following concentrations: 0.0, 0.1, 1.0, 10, 100 and 1000 ?l/L for 12 h. The second experiment consisted of different solutions: Flower?, Floralife?, Florissant?, chlorine and distilled water, pulsing for 24 h. The concentrations of ethylene did not affect the longevity of the flowers. Treatments with Floralife?, Flower?, distilled water, Florissant? and chlorine achieved a longevity of 11.75, 11.00, 10.75, 9.75 and 7.25 days, respectively. The Flower? solution had similar longevity to that obtained with distilled water and Floralife? and, it also allowed the hydration of the stems longer.
