To evaluate the rooting potential of hardwood and softwood stem cuttings of four plum cultivars (Carmesin, Gema de Ouro, Januária, e Reubennel), was used exogenous applications of indolbutyric acid (IBA) in different concentrations (0, 1000, 2000 and 3000mg L-1). The experimental was carried out at Universidade Federal de Lavras (Lavras, MG, Brazil) in 1997. After the treatments, the cuttings were planted in washed-sand. The hardwoods cuttings were placed in shade-house and the softwoods cuttings in greenhouse. Were evaluated the rooting percentage, root number and root length. The best results were obtained with softwood cuttings of the cultivar Januária (54,62%). The rooting formation, root number and root length of the softwood cuttings were influenced by IBA.
