Response of different chemicals on vase life and petals quality of Oriental lily cv. ‘Crystal blanca’

Lilium is one of the foremost cut flowers in the international market. The main problem is blockage of xylem vessels and insufficient water uptake takes part in the short vase life of cut flowers. An investigation was made to study the effect of preservative and biocides such as Sucrose (4 mg), Aluminum Sulfate (60 mg), CaCl2.2H2O (30 mg), CuSO4 (90 mg) and Ethanol (6 ml) on vase life of Oriental lily cv. 'Crystal Blanca'. Postharvest characteristics such as vase life, solution uptake and petal quality were evaluated. The experiment was laid out according to Complete Randomized Design (CRD) with six treatments and three replications and Tukey test was applied to check the differences among treatments. Maximum vase life in terms of days was observed in treatment Sucrose (9.33 days) followed by Aluminum Sulfate (7.00 days) and Ethanol (6.33 days). Maximum solution uptake was also recorded in CaCl2.2H2O (151.67 ml) followed by Ethanol (106.67 ml). In present context, sucrose treatment was distinctly able to enhance the vase life of Oriental Lilly and it could be a source to increase the value of this flower
