Descripción de características anatómicas y organolépticas de la madera de cinco especies forestales procedentes del cantón Lago Agrio, provincia de Sucumbíos.

Abstract

The objective of this research was to describe the anatomical and organoleptic characteristics of the wood of five forest species from Lago Agrio Canton, Sucumbíos Province, in order to provide adequate information and a better use of it. The Herbariumof the Escuela Superior Politécnica de Chimborazo (CHEP) was used for dendrological identification. For the determination of microscopic characteristics, cubes of 2 cm per edge were obtained, for softening, glass jars were placed in the autoclave with distilled water and covered with aluminum foil in cycles of one hour depending on the wood, withthe help of the rotary microtome, the transversal, tangential and radial cuts were made, Once the wood slices were obtained, they were placed in Petri containers to perform the different stains with safranin, astrablue and the combination of astrablue/safranin in timesof 10, 20, 30 seconds, once the plates were attached, all the anatomical structures were observed in the three sections. To determine the macroscopic characteristics, test tubes were made with dimensions of 16 x 6 x 1.5 cm, in which characteristics such as color, odor, flavor, marbling, grain, texture and brightness of each of the samples were observed.For the statistical analysis, comparative tables were made taking into account the perimeter and quantity of pores, giving as a result that, in the microscopic characteristics,it was visualized that the five species presented solitary pores in their majority, followedby multiples pores of two and three. It is concluded that the species under study belong to different families except for Inga alba and Parkia balslvii, which belong to the same family. It is recommended to carry out phenological and anatomical studies of the same species in different sectors in order to generate a wide range of information.
