Rooting of herbaceous blueberry cuttings: influence of the base incision and indolbutiric acid

Blueberries (Vaccinium sp.) are species of temperate climate that, for occasion of the vegetative period, produce large amount of vegetal material that can be used in the propagation. This way, with the aim of verifying the rooting potential of different herbaceous cuttings of blueberry cultivars, with the use or not of indolbutíric acid and base injury. The work was carried out in two experiments, having tested the capacity of rooting of the following cultivars Florida, Woodard, Bluegem, Bluebele, Clímax and Briteblue. In the first experiment, cuttings of cultivars were treated with IBA (0, 2500, 5000 and 7500mg.L-1). On the second experiment one used 2000mg.L-1 of AIB, in cuttings with and without injury in the base. The experimental design was the completely randomized with adjusted repetitions and experimental units for each experiment. After 90 days, it was evaluated rooting percentage for each cultivar submitted to IBA treatment with different doses. The use of the indolbutíric acid and the cutting injury, did not stimulated the emission of adventitious root; the cultivars present genetic potential of differentiated rooting, so that, the Bluebelle presented higher percentage rooting cutting, and the Climax, the lowest percentage.
