The aim of this work was to evaluate the effect of gibberellic acid (GA3) and N-(phenylmethyl)-1H-purine-6-amine + GA4+7, on the development of A. squamosa L. rootstocks. The experiment was arranged in a completely randomized design, with 7 treatments and 5 replicates. The treatments consisted of control, 25, 50 and 75 mg.L-1 of GA3, as well as 25, 50 and 75 mg.L-1 of N-(phenylmethyl)-1H-purine-6-amine + GA4+7. The following parameters were evaluated: stem length; number of leaves; stem diameter; in addition to shoot and root dry weight. The results showed positive effects of growth regulators application on A. squamosa L. rootstocks; the best results were obtained with GA3 that increased the development of the seedlings.
