Effect of Bactericides and Sucrose Pulsing on Longevity and Vase Life of Rose Cut Flowers

The vase life of rose cut flowers was determined by various Physiological factors that determine the rate of their senescence. The vase life of the rose cut flowers studied was pronged by the 8-HQS treatment. The best concentration was 100 ppm, when combined with sucrose 3% gave negative effect. AgNO3 in different concentration, significantly Result in maximum vase life compared to other treatment, while sucrose recorded the lowest vase life especially under lower concentration. The percent of wilting was minimized as a result of using this treatment . However the percent of wiling increased .With the increasing in concentration of 8-HQS , that wilting occurred after 10,8 and 7days of vase life for 100,200, and of 8-HQS in rose. The longest period to reach percent of wilting was obtained by AgNO3 at 30ppm13 days for rose. The best treatment of each chemical retarded the chlorophyll as well as carbohydrate degradation during postharvest life. These physiological processes are connected to cut flower longevity and quality.
