Abstract

Among the plant growth regulators, GA3 showed better results as compared to NAA and control. GA3 at two concentrations (100 ppm and 150 ppm) increased the water uptake, vase life, fresh weight, percentage of opened florets, floret diameter and length of florets. Citric acid at 0.5% was most effective in promoting water uptake, vase life, floret opening, increasing diameter and length of first, third and last fully opened pair of florets, while citric acid @ 0.1 percent was most effective in influencing the fresh weight and length of rachis.
