Evaluación dasométrica y cualitativa de cuatro procedencias de Ochroma pyramidale Cav (Balsa) en la Hacienda la Mira del Cantón Buena Fé,provincia de Los Ríos.

This research was condueted from May 28, 201 O until April 28, 2011, on thc farm of Mr. Mauro Flores Chavcz located in the canten Buena Fe province of Los Rios Ecuador in che Hacienda La Mira and is located between che eoordinates E 990225 and N 667302, comer of Mr. Loaiza; E 693867 N 9917956 and, with Mr. Stuart Gallo, NEN 9915607 and 693812, Rio Tongle; E 692357 N 9917048 and. The plantation has an irregular topography by 60%. The aim of the research was 10 cstablisb plots of 20 trees of four from two planring densities (3 x 3 rn, 4 x 4 m) with two replications, the experimental units wen, evaluated 6 central trees of each plot. Fonned two blocks were tested with four sourccs in two replications with two 4x4 3x3 distances. The experimental arca of 7315 m2, used a randomized block dcsign with two replicares. Origins were evaluated, beight, diameter, basal area, bcigJ,1 of bifurcation, branch nwnber and survival raft seeds of different places, plus lhe trees obtaincd from the difentes arcas. Toe land used was applied manual control cleaning, and buoys boyado it manually. Using a real framework planting. The variables hcight, diameter, basal area, height and number of branch bifurcation were evaluated at lhrec, six and twelve months, while survival was three months, ie at lhrec, six, nine and twclve months respectivcly. From 60 to 365 days of evaluation for thc variable height di!Tcrence was not statistically significant Ochromo pyromidol• forest specics. Tukcy 5% probability of error, while for thc variable wide, there was no statistically significan! difference, ie thc four sourccs behavcd the sarne. While for the variable basal arca just as the evaluated variables were not statistically significant difference for 365 days. The survival if statisrically signilicant differences at 360 days of cvaluation, reporting a higher percentage of Quevedo origin, while lhc nurnber of branching showcd no stalistically significant di!Tercncc is that in lhc four sourccs bchavcd the same. Because thc results of this study are lhc rcsull of an initial assessment, it is necessary 10 continue it, as this wíll only represent results of a year of research, to determine if the four sources of Ochromo pyromldal, have the same growth dynamics 10 lcnow and thus recommcnded for commercial plantation establishment, and thus promote forestry development in Ecuador.
