A trial was carried out aiming to evaluate the vegetative propagation by cutting for the vine rootstock '43-43'. Softwood shoots collected in January - and semi-hardwood shoots collected in March - were divided in two lots: one of the cutting was taken from the apex and the other from the base. The cuttings were immersed in solutions, by 10 minutes, containing different doses of indole butyiric acid (0, 1000, 1500, 2000, 2500 or 3000 mgL-1), totalizing 12 treatments for each epoch of rooting. After that, the cuttings were planted in polypropylene vases with sand and kept under misty system irrigation. Sixty days after planting the cuttings, for each epoch, the following variables were evaluated: percentage of rooted cuttings, length and fresh weight of roots and percentage of sprouted cuttings. The softwood and semi-hardwood cuttings presented high percentage of rooting (66% and 68%, respectively) even when not treated with the plant regulator. Apical cuttings presented higher length and fresh weight of roots. The IBA application reduced the percentage of rotting and sprouting of softwood and semi-hardwood cuttings. The semi-hardwood cuttings that were treated with IBA at 1,000mgL-1 showed the highest length and the freshest weight of roots.
