The aim of this work was to increase the rooting of stem nodal segments of tree seedling using different concentrations of IBA and injuries between the knots. Stem cuttings of fig tree 'Roxo de Valinhos' were collected at the moment of the hibernal pruning (July), standardized with 20 cm in length, diameter of 12 mm and five knots. In half of the stakes, an injury was done between the knots [square cuts with dimensions of 1 (one) cm]. The stakes were treated with different concentrations of IBA (0, 1.000, 2.000 and 3.000 mg L-1) and fully buried in the horizontal position at 5 cm of depth in moist sand under nursery (50% of brightness) condition. After 90 days, the rooting and sprouting of stakes, the length of shoots, the rooted nodes, number of roots and shoots per cutting and knot and yield of seedlings (average number of nodes rooted in sprouted cuttings) were evaluated. The rooting of nodal segments is an alternative for increasing the rooting of fig tree seedlings, being indicated an injury between knots associated to the application of 2000 mg L-1 of IBA.
