The objective of this work was to verify the effect of indolbutyric acid (IBA) and hydrogen cyanamide on the rooting of hardwood cuttings of three cultivars of plum tree (Pluma 7, Rosa Mineira and Amarelinha), treated with IBA (0 and 4,000 mg L-1) and hydrogen cyanamide (0, 0.5 and 1%). The experiment was carried out from June to September 2004, in greenhouse, in a completely randomized design, with four replicates and 12 cuttings per plot in factorial 3x3x2 (cultivars x hydrogen cyanamide concentrations x IBA concentrations). Root formation was not influenced by IBA aplication, in Pluma 7, Rosa Mineira and Amarelinha cultivars, and the application of hydrogen cyanamide 0.5% affected rooting of the Amarelinha cultivar.
