AB - Due to the economic importance of longevity of cut flowers, this study was conducted to evaluate the effect of nano-silver, silver thiosulfate, hydroxyl quinoline and a natural compound, thymol, on vase life and number of bacteria in cut stem ends of Rose flowers cv. Dolce vita. Cut flowers were transferred to laboratory at 22 ± 1ºC temperature and 60 ± 5% relative humidity. Cut flowers were pulse-treated with 2.5, 5 and 10 mg L-1 nano-silver, 0.5,1 and 2 mM silver thiosulfate, 50, 100 and 200 mg L-1 hydroxy quinoline and 50, 100, 200 mg L-1 thymol with 5% sucrose. Experiment was conducted in a completely randomized design with 8 replications and one flower in each experimental unit. Based on the results, all of the treatments showed positive effects on the vase life of flowers and number of bacteria in cut stem ends during the vase period, and no bacteria were found in 5 and 10 mg L-1 SNP treatments. The nano-silver (5 and 10 mg L-1) treatments showed the greatest mean longevity (19 days). Considering the results and economical and functional aspects of the tested materials, nano-silver treatment can be used for increasing the vase life of ‘Dolce vita’rose.
