The technological study of a timber species is very costly, due to the specialized equipment and personnel needed, which is why, through the author's many years of experience, she found the explanation of details in the microscopic anatomical sections of the different timber species, which confirm the results found when carrying out the technological investigations (chemical, mechanical physics and sound transmission) and thus be able to predict without carrying out the technological practices, some characteristics of them, through the slides of the anatomical sections.In this publication you will find the results of both the anatomical cross-sections and the technological characteristics, which will facilitate the selection of woods for different purposes in an approximate, but safer way than what is advised in the wood-related business.
