Abstract
The experiment was laid out in a completely Randomized Design in Factorial concept with 24 treatments and replicated thrice. The treatment consisted of eight different colour dye chemicals each of 1000 ppm and three concentrations of floral preservative. The preservative Al2SO4 500ppm + sucrose 2% significantly enhanced fresh weight, uptake of water, vase life, minimum physiological loss of weight and loss: uptake ratio. However the preservative Al2SO4 250ppm + sucrose 2% showed minimum loss of water and maximum diameter of florets. All edible dye was retained initially good shade expect black ink whereas, effect of different dyeing chemicals and their concentrations were found non-significant on flower qualities and vase life of tuberose. At higher concentration colour and dark shade was obtained quickly except black ink. In case of different dye chemicals, their concentration and duration of absorption found non-significant effect on flower qualities and vase life of tuberose. At higher concentration with higher absorption time obtained dark colour shade of spike.
