ÁCIDO INDOLBUTÍRICO NO ENRAIZAMENTO DE ESTACAS DE MARACUJAZEIRO DO CERRADO

Abstract

Most academic studies on passion fruit culture are directed at the Passiflora edulis species for their commercial value, however, the agronomic potential of wild passion fruit species has not been fully explored, deserving further attention and research in the area. The objective of the present work was to evaluate the rooting of passion fruit cuttings from the Cerrado treated with indolbutyric acid in different concentrations. Stakes with two buds were used and harvested in the municipality of Uruaçu-GO. The cuttings were subjected to the application of five concentrations of indolbutyric acid (0, 250, 500, 1000 and 2000 mg L-1). The experimental design was a completely randomized design, with five replications and 10 cuttings per experimental unit. The cuttings were evaluated 45 days after planting. The variables used were the stakes: live; with remaining leaves, rooted and cuttings with calluses. The dosage of 1000 mg L-1 of IBA promoted a greater number of live cuttings and, consequently, greater rooting of stem cuttings for Passiflora nitida.
