An experiment was carried out during winter season in Department of Floriculture and Landscape Architecture, University of Horticultural Sciences, Bagalkot. The experiment was conducted in randomized block design with 5 treatments or growth regulators of different concentrations along with one control as water spray. Gibberellic acid (G1- GA3 at 200 ppm), NAA (G2- at 60 ppm), Cycocel (G3- CCC at 1000 ppm) and TIBA at 1000 ppm (G4) replicated thrice to evaluate the effect of these plant growth regulators on flower quality parameters like flower diameter, individual weight of the flower and vase life was varied significantly due to various growth regulators. Flower quality parameters were best in the plants sprayed with GA3 at 200 ppm. In the present study maximum chlorophyl and xanthophyll contents were noticed in the plants sprayed with the GA3 at 200 ppm, followed by CCC at 1000 ppm in various crop periods.
