Propagação vegetativa de maracujazeiros (Passiflora spp.)

Abstract

Native to Brazil, passion fruit has great economic, social and food importance, being cultivated predominantly by family farmers. Most Brazilian orchards come from seedlings propagated by seeds. However, the production of seedlings by asexual or vegetative methods, such as stofa and grafting, has some advantages promoted by cloning, such as the multiplication of plants resistant to pests and diseases and the uniformity of plants with productive characteristics in the field. The work was carried out at UNEP­Fruticultura, Federal Technological University of Paraná, Campus Dois Vizinhos and aimed to propagate passion fruit seedlings through cutting and grafting techniques, where the cuttings of cultivars BRS Gigante Amarelo, BRS Pérola do Cerrado and SCS437 Catarina were submitted to different concentrations of indolburic acid (0, 1500, 3000 and 4500 mg. L­1) and, in grafting, the cultivars BRS Pérola do Cerrado and BRS honey from the Cerrado will serve as rootstocks for the cultivars BRS Gigante Amarelo and SCS437 Catarina. The highlight is the cultivar BRS Gigante Amarelo in the experiment with cutting, which demonstrates greater rooting and survival, concentrations of 1500 to 4500 mg. L­¹.
