Abstract

Cuttings obtained from current year twigs and from basal sprouts of 12 tree species growing at Floresta Nacional de Irati, Parana State, Brazil, were treated with 3000 mg∙kg-1 indole-butyric acid (IBA) and a commercial natural rooting solution (Rooter Bioflora®). Rooting of cuttings ranged from 2% to 69% suggesting practical possibilities of macropropagation for some of the species. IBA treated cuttings showed better rooting potential for canela-amarela, while for canela-sassafrás, erva-mate and pessegueiro-brabo, the natural rooting solution was more efficient. The species angico-branco, cambuí, canela-guaicá and guaçatunga showed a trend for natural rooting. Six of the studied species presented rooting rate greater than 30% suggesting use of cuttings as an alternative for multiplication.
