Descripción organoléptica y anatómica de la madera de cinco especies forestales, procedentes de la parroquia Talag, cantón Tena, provincia de Napo.

Abstract

The present investigation proposes: to describe organoleptic and anatomical of the wood of five forest spies, coming from the parish Talag canton Tena, province of Napo; the speciesMwere identified in the ESPOCH Herbarium. Wood with dimensions of 15 x 9 x 2cm analysing the organoleptic characteristics. The anatomical characteristics were sized cubes with a measure of 2 cm3 to soften it by placing the samples in jars, of glass with distilled water of known volume covered with aluminium foil in the autoclave at a temperature of 121 *C, pressure 1.1 atm cuts were made of the tuhree planes, transverse, tangential and radial with the rotary microtome; then it was stained with Astrablue / Safranina and we observed the structures of the three planes. To calculate the density, one cube of each sample was weighed for the volume, it was calculated with a calibration: using the density calculation formula, resulting in Puoteria glomerata being of high density and Piptocoma discolor is low. To determine the pH, 20 grams of the substrate (sawdust) was weighed and distilled water was placed forming a homogeneous mixture to then take the pH Cabralea canjerana obtained alkaline pH and the remaining four species an acidic ph. Finally, from the previous evidence they created comparative charts by performing a statistical analysis.
