In agreement with to enhancement scion production ofRhododendron x simsii Planch trough the vegetative propagation in shorter time, it was intended to study the effects of different substrates and NAA concentration. The experiment was in factorial design 3x4 with three substrates (sand, hush rice and humus) and four NAA concentrations in the powder form (0; 2.5; 5.0 and 7.5%). The cuttings used had 100 mm length without apical meristem with two leaves cut in half. Those were put to rooting in trays of 128 cells, for 90 days in which were evaluated: length, surface, volume and root diameter and percentage of rooted, surviving and dead cuttings and number the buds. It can be conclued that the greatest of rooting was obtained in the substrates hush rice and the 5% of NAA.
