Considering the great interest for the plum tree in the fruit market, there is the necessity of searching for more efficient techniques in the plum plant propagation with quality and high uniformity. So this work aimed at verifying rooting potential of hardwood cuttings of 12 to cultivars of the plum tree (América, Amarelinha, Letícia, Pluma 7, Reubennel, Rosa Mineira, Santa Rita, Santa Rosa, Simka, The First, Wade and XV de November) treated with indolbutiric acid (IBA), in concentrations of 0, 1000 and 3000mg L-1, in fast immersion per 5 seconds in its basal part. The study was developed from June to September, 2004, in the EMBRAPA Technology transfer, located in the city of Canoinhas, SC. Hardwood cuttings had been collected first plants of 2 years situated in green-house and standardized with an average length of 12cm and diameter six mm, being conditioned in polystyrene trays expanded with 72 cells of 0,000015m3, contend vermiculita as substratum and kept in house of vegetation without intermittent mist per 97 days. The experimental delineation was entirely randomized with four replicates and 12 cuttings per parcel. The biggest rooting percentages (above of 70%) had been gotten in the cuttings of them to cultivate XV de November, Rosa Mineira and Santa Rita. The application of IBA 1000mg L-1, was the best in the rooting of cuttings of plum, given biggest number of roots and length of the roots.
