Wood characterization of Tectona grandis L. F. cultivated in Brazil: a review of the last 30 years

Abstract

Worldwide, Tectona grandis (teak) is recognized for its productivity and the quality of its wood. The Brazilian market is already seen as a great potential for consumption and production of teak wood. Therefore, the objective of this work was to characterize the teak wood grown in Brazil through a bibliographic survey of the results already available. In general, it was found that the teak wood planted in Brazil has a certain variability in its technological properties, and these variations are due to the origin, genetic material, age, planting location and the cycle used in the management of the forest. In a way, we still do not have much research on the quality of teak wood, and it would be important to implement research programs and experiments that consider the different genetic materials, growing environments, planting spacing, silvicultural tracts and ages of cutting, to allow greater knowledge about the growth and the factors that can influence the quality of the wood to be produced.

Radial variation of wood density and fiber morphology of two commercial species in a tropical humid forest in Southeastern Peru

“…Tropical species such as Anadenanthera peregrina, Ochroma pyramidale, and Schizolobium parahyba Var amazonicum showed the same type of increasing radial variation from pith to bark as J. copaia (Rueda and Williamson, 1992;Valente et al, 2013;Lobão et al, 2012) and the same behavior was found in tropical forest plantation species such as Guazuma crinita, Schizolobium parahyba, Tectona grandis, Toona ciliata, (Chavesta et al, 2020;Lima et al, 2021;Melo et al, 2018;Ribeiro et al, 2011). On the other hand, the tropical species Cariniana legalis also did not present any significant trend of radial variation in the pith-bark direction, the same as the species H. crepitans (Lima et al, 2011;Ribeiro et al, 2011), which does not exist a significant difference in the radial variation of wood in the species H. crepitans is favorable for industrial transformation processes (Plaster et al, 2008;Rios et al, 2018).…”

GROUPING OF CLONES OF 4-YEAR-OLD Eucalyptus spp. FOR PULP AND PAPER

“…New studies on wood quality must consider different genetic materials, growing environments, planting spacing, treatments and cutting ages, to allow greater knowledge about growth and factors that can influence the quality of wood produced and the adjustments that can help with forest management, processing and the most appropriate use of wood, in order to consider the best costbenefit ratio (Lima et. al.…”

Fundamentos para fabricação de um medidor de deslocamento para determinação das constantes elásticas da madeira, considerando a sua anisotropia

“…A análise de desempenho de qualquer componente estrutural requer o conhecimento das propriedades elásticas do material que o constitui, (Lima, et al, 2021e Santos, et al, 2020. Muitos critérios de resistência que existem apresentam restrições em materiais heterogêneos e anisotrópicos, com propriedades de elasticidade e de resistência direcionais, como a madeira Nicolas et al (2009).…”
