Abstract: The growth regulators from gibberellins, when applied on plants, might improve physic and physiological features, stimulate cell division and elongation, this study aimed at evaluating the influence of gibberellic acid doses applied exogenously on bean crop through seed treatment, and analyzing its effects on morphological attributes of seedlings and physiological quality of the seeds produced. The experimental design was completely randomized design, with treatments corresponding to the doses- zero (distilled water only), 50, 100 and 200 mg L-1, arranged in four replicates. The use of gibberellic acid in bean seeds did not result in changes on the number of leaves, leaf area, dry mass of leaves and stem. Applications of foliar gibberellic acid potentiated stem height and root dry mass of seedlings.
