Effect of pulsing with sucrose and sodium hypochlorite (NAOCL) on extension of vase life of cut Chrysanthemum cv. arctic queen

Abstract

The present investigation was carried out in the Department of Floriculture and landscape Architecture laboratory, College of Horticulture, Rajendranagar, Hyderabad during the year 2017-2018, 2018-2019. The experiment was conducted with two different pulsing chemicals i.e. sucrose and sodium hypochlorite. The main objective of the investigation was to find out the efficacy of different pulsing chemicals on physical (fresh weight of flower, diameter of flower, percent neck bending, vase life and over all acceptability of flowers), physiological (water uptake, transpiration loss of water, fresh weight change, relative water content, chlorophyll content in calyx), biochemical parameters (TSS of petals, pH of vase solution, optical density of vase solution, electrolyte leakage) in two days interval during the vase life period of cut Chrysanthemum. The experiment was laid out in completely randomized design with factorial concept and replicated thrice. Among the two pulsing solutions, sucrose 10 percent was very effective in increasing the fresh weight of flower (8.26 g), flower diameter (6.9 cm), water uptake (13.76 g), fresh weight change (123.76 g), relative water content (89.36%), chlorophyll content of calyx (36.90), Total soluble solids (4.0 degrees), over all acceptability of flowers (9.22), vase life of Chrysanthemum cut flowers (10.23 days). It has led to lowest electrolyte leakage (82.03%) and transpiration loss of water (12.04 g/f).
