The objective of this experiment was to evaluate the influence of the growth regulators NAA (naftalen acetic acid) and BAP (benzilaminopurin), in the increase of the angle of insertion of the branches in apple trees. The experiment was driven in a commercial orchard area of Lages/SC, where has been cultivated Imperial Gala and Fuji cultivars on rootstock Marubakaido, testing different doses of the regulators compared with the conventional bending. The regulators were applied with cotton aid, in the superior part of the branches in growth, in the insertion between the branch and the stem. The results evidenced that, even NAA tends to have a good effect in the bending of branches, in the doses of 200 to 500 ppm, the conventional practice to increase the angle of insertion of the branches, through the use of toothpicks, continues being the best bending method.
