Evaluación de la eficiencia del ácido indolbutírico (AIB) en el enraizamiento de mini estacas deEeucalyptus urophylla x grandis (Eucalipto urograndis), cantón Buena Fe, provincia Los Ríos.

Abstract

The following research work has the purpose to: Evaluate the efficiency of the índole butyric acid (AIB) in the rooting of mini stations of eucalyptus urograndis (Eucalyptus urophylla x Eucalyptus grandis), Buena Fe Canton, Los Ríos Province, the study was installed in the vivarium “Los Angeles” where vegetative material was extracted from three cultivars: L.A-10, E-154, E-71J and four doses were applied of indole butyric acid (AIB), of 0 ppm (T1), 500 ppm (T2), 1000 ppm (T3), 2000 ppm (T4). In our investigation it was obtained that the interaction the crop L.A-10, with the T4 (2000 ppm) the highest survival rate was obtained with 100%; at 17 days after planting. It was determines that indole butyric acid helped to accelerate the development of the roots in the mini stakes in the cultivation E-154 interacting with the T2 so it was recommended that the application of 500 ppm of AIB. It was determined that the crop L.A-10 together with the treatments 3 (T3), treatment 4 (T4), obtained the highest measure of biomass quality an in the development of height respectively, also this cultivate in the variable DAC together to the treatment 1 (T1), it was obtained the highest measure. Which indicates that the crop L.A-10, it is determined that there are significant differences, where the crop E-71.J together with the treatment 2 (T2), with the application of 500 ppm, it is the combination that produced the greatest number of sprouts. Clue Words: INDOLE BUTYRIC ACID, ROOTING OF MINI STAGES, VEGETATIVE PROPAGATION.
