Resumo:  ABSTRACT: The framboseira-negra has a potential for cultivation in Brazil, due to the fact that this fruit produces high quantities of fruits, which confer a high quality jelly. However, their propagation is an obstacle to the establishment of commercial plantations. Production and expansion of a fruit is directly linked to the propagation method and the quality of its development. Given the above, the aim of the present study was to evaluate the use of stem cuttings and IBA in asexual propagation of black raspberry. Two experiments being conducted in greenhouse conditions were performed. Stem cuttings were taken from didactic orchard, with matrix plant of four years, which were the experiments. The first experiment was carried out in factorial 3x2, with cuttings taken from three regions of the plant branch matrix (apical, median and basal) x two treatments with IBA (without IBA and 2000mg L-1 IBA), containing four repetitions and fifteen cuttings per repetition. The second experiment consisted of a 4x2, with four sizes of cuttings (5, 10, 15 and 20cm) x two treatments with IBA (without IBA and 2000mg L-1 IBA), with four replications and fifteen cuttings by repetition. After eighty days, the percentage of rooted cuttings (%), average number of roots and shoots for cuttings, the longest root length (cm) and fresh and dry biomass of shoots (g) were assessed. Best results in the formation of root system were observed in middle and apical stem cuttings. Stem Cuttings between 10 and 20cm obtained better results for rooting. There is no need to use IBA rooting of cuttings of black raspberry.
