A significant improvement in vase life of rose cut flowers was occurred when treated with 30 ppm silver nitrate and the effect was further improved when sliver nitrate at 30 ppm combined with 3% (w/v) sucrose which attained the best result compared to other concentrations of sucrose . Also the per cent of wilting was minimized , beside chlorophyll as well as carbohydrate degradation had been retarded during the postharvest life as the result of using this combination treatment.
