Abstract

The impact of gibberellic acid (GA3) and benzyl adenine (BA) dose and application timing on vase life of gypsophila was examined. Freshly cut gypsophila flower stalks with pre harvest sprays of growth regulators G1- GA3 at 150 ppm, G2- GA3 at 300 ppm, G3- GA3 at 450 ppm, G4- BA at 150 ppm, G5- BA at 300 ppm, G6- BA at 450 ppm, distilled water spray - G7 and were applied twice at S1- 30 and S2-at 30 and 45 days after pruning are harvested from the experimental plot early in the morning when 30 to 40% of flowers in the stalk open and held in vases containing 3 % sucrose solution flower stalks are harvested from the experimental plot early in the morning when 30 to 40% of flowers in the stalk open and held in vases Water absorption, fresh weight change, water loss by transpiration, physiological weight loss, 50 % discolouration and vase life. Among all the treatments, the flowers sprayed with GA3 at 450 ppm and single spray recorded maximum water uptake (13.19 g), transpirational loss of water (6.19), fresh weight change (62.51 %), dry weight of flowers (2.09), 50 per cent discolouration (13.41 days), Vase life (14 days) and minimum physiological loss in weight (1.78 g).
