The present investigation was carried out at Model Floriculture Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, during 2009-10 to 2010-11 to study the effect of azadirachtin and other chemicals on post harvest life of rose cv. Grand Gala. During the entire course of study, three experiments were conducted i.e. standardization of holding, pulsing and bud-opening solutions for two consecutive years. Flowers of uniform length i.e. 40 cm, were used at one petal unfurl stage for holding and pulsing treatments and at loose tip stage with no petal unfurl stage for bud-opening solutions. The experiment on standardization of holding and bud-opening solutions was laid out in Completely Randomized Design with 16 and 11 treatments, respectively, replicated thrice. Holding solution containing 0.25 ppm azadirachtin + 2% sucrose and 200 ppm citric acid resulted in increased flower diameter, water uptake, water balance, gain in fresh weight, vase life, appearance score and minimized water loss/water uptake ratio and microbial count in vase solution. Bud-opening solution containing 0.25 ppm azadirachtin + 3% sucrose and 200 ppm citric acid increased all the economical parameters and the solution containing 50 ppm 8-HQC + 3% sucrose improved the water relations. The experiment on standardization of pulsing solution and durations was laid out in Factorial Completely Randomized Design with 20 treatments replicated thrice. Pulsing of flowers with 4% sucrose + 0.25 ppm azadirachtin for four hours resulted in increased flower diameter, water uptake, water balance, gain in fresh weight and vase life and minimized water loss/water uptake ratio and loss in fresh weight during senescence. |
