Estimación de la densidad básica de la madera en tres especies tropicales en Chiapas, México

Abstract

It has now been shown that the basic density of wood is related to tree growth and carbon storage capacity, it also providesinformation such as the resistance, durability and quality of the wood, with this, the efficient use of wood in tropical species isdetermined. The objective of this research was to estimate the basic density of wood in three tropical species (Tectona grandis L. f.,Gmelina arborea Roxb. and Cedrela odorata L.). To estimate the basic density of the species, the empirical method was used,which consists of extracting a core from the tree using a pressler drill, at a breast height (1.30 m), once the 20 cores per specieshave been obtained, the small samples are dehydrated in a drying oven until a constant temperature is obtained, through this thebasic density per species was obtained. Once the density data was obtained they were subjected to an analysis of variance and latera Tukey test was applied. The statistical analysis indicates that, if there are significant differences between the species, where thehighest basic density occurred in Tectona grandis L. f. with 0.59 g/cm³, followed by Gmelina arborea Roxb. 0.44 g/cm³ and finallyCedrela odorata L. with 0.37 g/cm³, these values according to the wood classification indicate that teak and melina have mediumwood and cedar has low wood
