With the objective to investigate the in vitro behavior of salix (Salix humboldtiana Willdenow), leaf and nodal segments were inoculated in WPM medium supplemented with NAA and IBA. In leaf explants, the presence of these growth regulators, isolated or in combination, induced the formation of adventicious roots. Root hairs were only observed when NAA was present. In nodal explants, while the combination of 2,68 µM ANA + 2,46 µM IBA induced bud growth, the other treatments (4,92 µM IBA; 2,68µM ANA + 4,92 µM IBA; 5,37 µM ANA + 4,92 µM IBA; 5,37µM ANA) induced the formation of adventicious roots.
