|Abstract:||The study was conducted at the Department of Floriculture and Landscape Architecture Kittur Rani Channamma College of Horticulture, Arabhavi, University of Horticultural Sciences, Bagalkot, during kharif and rabi season from June, 2015 to February, 2016, to know the influence of foliar spray of plant growth regulators on growth, flowering and yield of crossandra (Crossandra undulaefolia Salisb) genotype ACC-1. The experiment was laid out by adopting Randomized Completely Block Design (RCBD), having nine treatments with three replications. The treatments were comprised of two concentrations of Gibberellic acid (100 and 200 ppm), NAA (100 and 150 ppm), TIBA (100 and 150 ppm), Ethrel (50 and 100 ppm) and control (water spray). The plant growth regulators were sprayed four times viz., 15, 30, 45 and 60 days after transplanting. Among the growth regulators the plants sprayed with the Gibberellic acid (200 ppm) resulted significantly maximum plant height, number branches per plant, plant spread, leaf area, dry weight. While, the yield and quality parameters like days taken to flower spike initiation, days taken to first harvest,duration of flowering, flower diameter, number of flowers per inflorescence, number of spikes per plant, 100 flower weight, flower yield per plant, flower yield per plot, flower yield per hectare, chlorophyll and carotinoid estimation, shelf life, corollar length and physiological loss in weight were also observed in plants sprayed with the Gibberellic acid (200 ppm).|
