Abstract
An experiment was conducted at Rooftop Garden under 2abotech lab, Department of Horticulture, Sher-e-Bangla Agricultural University, Bangladesh during November 2012 to July 2013 to find out growth and yield performance of potted Gerbera against foliar application of different concentration of Gibberelic acid (GA3). Three varieties viz. V1 (red), V2 (brick red), V3 (pink) and four GA3 concentrations viz. G0: 0 ppm, G1: 100 ppm, G2: 150ppm, G3: 200 ppm were evaluated in the experiment. Maximum number of flower (22.1), flower bud diameter (3.6 cm), peduncle length (29.3 cm), peduncle diameter (1.9 mm) and flower head diameter (8.6 cm) were found from V2 while G2 provided maximum number of flower (24.0), longest peduncle (28.3), maximum peduncle diameter (1.7) but G2 and G3 both provided maximum flower bud diameter (3.1 cm) and flower head diameter (8.1 cm). V2G2 was found as the best treatment combination.
Key words: Gerbera jamesonii, Gibberelic acid and Different concentration
