ABSTRACT

The vase life of carnation cut flowers were studied to determine the physiological factors that affect there vase live and longevity. Cut carnation flowers were obtained from commercial grower in Taif, Sudia Arabia, and treated with 100, 200 or 300 ppm of 8-hydroxyquniline sulfate (8-HQS) and sucrose at concentrations of 1, 2, or 3%w/v. Longevity of cut carnation was determined on the basis of wilting, chlorophyll retention and carbohydrate degradation. After treatment the cut carnation were kept at room temperature (23+ 1 0C) at normal day light and natural ventilation. The vase life of cut flowers studied were prolonged by (8-HQS) treatment. The best concentration was 100 ppm. The effect was better when combined with 3% sucrose, which recorded the best vase life compared to other concentration of sucrose. The per cent of wilting was minimized as a result of using this treatments .However the per cent of wilting increased with the increase in concentrations of 8-HQS, and complete wilting occurred after 15, 14 and 14 days when treated with 100, 200 and 300ppm of 8-HQS respectively, while sucrose resulted in the lowest period to reach wilting. Also 8-HQS at 100ppm retarded the chlorophyll as well as carbohydrate degradation during the postharvest life. These experiments were carried out in the laboratory of the Department of Biology -Taif University- Sudia Arabia. The experiments were repeated three times with three replicates, and a completely randomized design had been used. The difference between means were performed using Duncan multiple range test at 0.05 level.
