Effect of different chemicals on physiological and biochemical parameters of cut stem Lilium cv. Pollyanna during post harvest period

Abstract

To increase the post harvest shelf life of Lilium flowers, experiments were conducted by using Preservative solutions viz. Nano Silver (50-ppm), Sucrose (50-ppm), 8-HQ and Distilled water. The experiment was conducted with total 14 treatments. The major reasons for less vase life of cut flowers may be due to nutrient deficiency, bacterial and fungal contaminations, water stress and vascular blockage. Maximum vase life was also found in NS 75 ppm + 8 – HQ 150 ppm + sucrose 2 per cent H10 treatment. Treatment combination of NS 75 ppm + 8 – HQ 150 ppm + sucrose 2 per cent can extend the vase life of harvested Lilium flowers by reducing the bacterial infection, improving the physiological and biochemical parameters for harvested flowers.
