Abstract
HERNANDEZ-ALVAREZ, Efrén; RUIZ-BLANDON, Bayron A.; GOMEZ-CARDENAS, Martín and QUINONEZ-BARRAZA, Gerónimo. Technological Analysis of Gmelina arborea Roxb. from Pure and Combined Juvenile Stands in Mexico. Colomb. for. [online]. 2024, vol.27, n.2, e21313. Epub Sep 06, 2024.

Gmelina arborea is a species that holds economic value in forest markets, primarily due to the versatility of its biomass, rapid growth, and timber quality. The main objective of this research was to evaluate the dendrometry, biomass, soil, and the physical and mechanical properties of the wood in two 18-year-old stands. In rectangular plots of 1000 m², dasometric information from 20 trees was collected, in addition to wood fractions for physical-mechanical tests in the laboratory. Statistically, mixed-stand G. arborea exhibited a larger diameter (7.3%) and stem biomass (5.1%), as well as an impact on mechanical properties (8.1%) and hardness on its various axes (long. 6.2%, rad. 1.5%, and tang. 6.3%). It is inferred that mixed stands contribute to greater biomass and better resistance and quality of wood in G. arborea.
