Abstract :Cut flowers last only for a few days maintaining their beauty and attractiveness. Thus, using appropriate preservatives could extend the vase life of harvested flowers. The study aimed to prolong the postharvest quality and vase life of cut rose. The experiment was laid out in Completely Randomized Design with 5 treatments and 10 replications insert ignore into journalissuearticles values(flowers);. The treatments insert ignore into journalissuearticles values(vase solutions); were as follows: T1- Filtered water, T2- 0.02 M STS + 2 % Sucrose, T3- 0.02 M STS + 2 % Glucose, T4- 250 mg/L HQS + 2 % Sucrose and T5- 250 mg/L HQS + 2 % Glucose. All treatments were kept at 25 °C and quality was determined by recording the relative fresh weight insert ignore into journalissuearticles values(%);, solution uptake, maximum flower head diameter insert ignore into journalissuearticles values(MFHD);, blueing symptom, senescence flower and vaselife insert ignore into journalissuearticles values(days); after 4 and 6 days of holding. Results showed detrimental effects of vase solutions with silver thiosulfate insert ignore into journalissuearticles values(STS); in combination with sucrose and glucose after 4 days. However, hydroxyquinoline sulfate insert ignore into journalissuearticles values(HQS); vase solution with glucose maintained a vaselife of 4.5 days. Maximum flower head diameter was better with HQS vase solution with glucose insert ignore into journalissuearticles values(84.42 mm); after 6 days compared to filtered water insert ignore into journalissuearticles values(66.01 mm);, but was statistically comparable with HQS vase solution with sucrose insert ignore into journalissuearticles values(82.34 mm);. Generally, vase solution of HQS with glucose manifested better results compared to other treatments in terms of percent weightloss insert ignore into journalissuearticles values(26.62 %);, maximum flower head diameter insert ignore into journalissuearticles values(84.42); and vaselife of 4.5 days after 6 days of holding.
