Evaluación de la calidad de plantaciones de balsa Ochroma pyramidale (Cav. ex Lam.) Urb. de un año de edad, en los cantones Valencia y Mocache, Provincia de Los Ríos.

The objective the research was to evaluate the quality of balsa plantations Ochroma pyramidale (Cav. ex Lam.) Urb. about one year of age in Valencia and Mocache, Los Ríos province. The study was conducted in established plantations were a year old of the project "Sowing Balsa" in different sectors within these towns, and nine sample units of 1000 m2 each. The methodology proposed by Camacho and Murillo (1997), for measurement and estimation of quantitative and qualitative variables per sample unit were recorded was used: diameter, total altitude, high fork, mechanical damage, plant health, insertion angle branch and stem straightness. To analyze the parameters of competition the following indices were used: Basal area, competition cup, relative spacing and Bal & Balmon. Quantitative variables were not significantly different between the cantons, qualitative variables showed differences between ranges and variable of quality presented differences between categories, obtaining as a result a Quality 2 (acceptable zone) for the Mocache canton unlike the Valencia canton was quality 3 (bad area), while the parameters determined that there is no competition between trees of different stands within these two localities. Depending on these results a proposal was developed that is oriented to a forest management plan for the balsa in its initial state.
