Descripción organoléptica y anatómica de la madera de cinco especies forestales, procedentes del cantón Santo Domingo, parroquia Alluriquín, sector Tinalandia.

Abstract

The present investigation is focused on: The organoleptic and anatomical description of five forest species from Santo Domingo canton, Alluriquin parish, Tinalandia sector: in order to identify the forest species, the Herbarium of the Higher Politechnic School of Chimborazo was used. For the organoleptic characteristic a comparison chart was elaborated, in which what was observed was detailed by using the sences: smell, touch,sight and taste. For the anatomical characteristic, the wood samples of the five species were exposed to a softening process, at a temperatura of 121? C, at a pressure of 1.1 atm; histolgical cuts were made of the transversal, tangential, and radial part of the microtome, and once the sheets were obtained, then they were placed in the combined dyeing 1:1 (Safranins / Astrablue). Subsequently, the observation of the plates, data recording and statistical analysis of the species were carried out. In the organoleptic characteristic it was demostrated that the five species are different, in the anatomical characteristics all the species presentd solitary pores mostly followed by pores multiples of two and three with the exception of Guarea kunthiana where pores multiples of two predominate. We can state that the combination of the two dyes allowed us to correctly visualize each of the structures.
