【 摘 要 】

Drymis brasiliensisMiers is a specie of the Winteraceae family, commonly known as cataia or pepper bark. This research was carried out with the aim to study the rooting of semihardwood cuttings, subjected to different concentrations of indolebutyric acid (IBA), collected in four seasons of the year (autumn, winter, spring and summer). Cuttings were prepared with 10-12cm length, keeping two halved leaves. Bases of cuttings were treated as follows: control (100% water), 0; 500; 1500; 3000; 4500 and 6000mg L-1IBA.One hundred and twenty after the planting the following variables were assessed: rooting percentage, number of roots per cutting, length of roots per cutting, cutting callus percentage, cuttings with new shoots and number of cuttings that maintained the initial leaves. The indolebutyric acid is not recommended for rooting of Drimys brasiliensiscuttings. The cuttings collected in winter were the ones that showed greatest rooting percentage (46.96%) for the production of nursery plant of Drimys brasiliensis.
