The effect of bioregulators GA3 and paclobutrazol was evaluated on flowering and yield of strawberry cultivars Oso Grande and Seascape. The experiment was carried out in Caldas, Minas Gerais State, Brazil. The treatments consisted of control (no application of bioregulators); GA3 at 40 mg L-1, in two applications (45 and 65 days after transplanting date); paclobutrazol (commercial product Cultar, 10%) at 100 mg L-1, 75 days after transplanting date; combination of GA3 + paclobutrazol, applied 45; 65 and 75 days, respectively, after transplanting date. The experimental design was a randomized complete block, with four replications, in a factorial 2x4. The response to the bioregulators GA3 and Paclobutrazol was cultivar dependent. 'Seascape', a day neutral cultivar, presented better results in relation to application of GA3 than 'Oso Grande', a short-day cultivar. Paclobutrazol applied 75 days after transplanting date reduced the flowering.
