Rooting of mini-cuttings and quality of plantlets of Cordia trichotoma

Abstract The objective of this work was to evaluate the effects indolebutyric acid (IBA) concentration, substrate composition and volume, propagule type on adventitious rooting quality Cordia trichotoma plantlets produced by mini-cuttings. Mini-cuttings were evaluated for percentage root number length at 30 60 days cultivation. Plantlets shoot height stem diameter 30, 60, 90, 120 Dickson index, leaves, fresh dry weights shoots roots also determined experiments carried out in a completely randomized design, with six replicates, greenhouse, evaluating different concentrations IBA, rooting. C. can be proper from mini-cuttings one or two buds multiple (apical) when treated 3,000 mg L-1 IBA planted 110 cm3 tubes containing equal proportions vermiculite.
