This study aimed at evaluating different kinds of cutting with variable bud number on rooting, budding percentage and development of grapes scions stock cv. IAC 572. A trial was carried out in a nursery at Embrapa in Petrolina, Brazil, in a randomized design, with four replications and five treatments, with 25 cuttings each plot. The treatments are the following: 1) Three bud ligneous cutting; 2) Two bud ligneous cutting; 3) One bud ligneous cutting; 4)Two bud herbaceous cutting and 5) One bud herbaceous cutting. At 60 days after planting, three bud ligneous cutting presented the greatest percentages of rooting (99%) and budding (99%) and best development of shoots and roots. However, these results are not significantly different (p>0.5) to the values obtained to rooting and budding using one bud ligneous cutting.
