1. Produção e decomposição de serapilheira em áreas de reflorestamento e floresta nativa no sul do Amazonas
Resumo A diversidade de espécies florestais é uma característica intrínseca do bioma Amazônico, sendo a serapilheira a principal responsável pela maior parcela dos nutrientes devolvidos ao solo. Dessa forma, o objetivo deste estudo foi quantificar a produção anual de serapilheira e determinar a velocidade de decomposição ao longo de um ano, compara

2. Litterfall decomposition of coffee shaded with Tectona grandis or in full sun
RESUMO A serapilheira é uma importante fonte de nutrientes para o solo e a sua decomposição pode ser influenciada pelos sistemas de uso do mesmo. Este estudo teve por objetivo avaliar a decomposição de serapilheira e seu estoque de macronutrientes em dois sistemas de cultivo do cafeeiro, sendo um sombreado (CS) e outro a pleno sol (CPS). O experimento f

4. CHARACTERIZATION OF INJURY CAUSED BY Coptotermes testaceus IN Tectona grandis PLANTATIONS IN BRAZIL
ABSTRACT Coptotermes testaceus (Linnaeus, 1758) is the most important species of heartwood termite of adult trees in forests planted in Brazil. This study aimed to characterize the injuries promoted by the heartwood termite C. testaceus in Tectona grandis commercial stands. Tree bark with extend carton material on the outside, forming external galleries and

5. BEHAVIOR OF THERMALLY MODIFIED WOOD TO BIODETERIORATION BY XYLOPHAGE FUNGI
ABSTRACT Thermally modified wood undergoes chemical, physical, and mechanical modifications, resulting in changes in resistance to wood biodegrading agents. The objective of this study was to evaluate the resistance to biodeterioration of thermally modified wood by the industrial process VAP HolzSysteme® of Eucalyptus grandis, Pinus taeda and Tectona grandi

6. STUDY OF THERMAL EXPANSION AND COMPRESSION STRENGTH OF THREE WOOD SPECIES FROM PLANTATIONS
ABSTRACT The objective of this study was to evaluate the effect generated by a thermal treatment on the dimensional changes and compression behavior of three wood species from commercial plantations (Eucalyptus nitens, Tectona grandis and Gmelina arborea). To accomplish the goal, dilatometric and compression tests were performed in the three directions of wo

8. DIAGNOSIS AND SPATIAL VARIABILITY OF SOIL FERTILITY AND CROP PRODUCTION IN A TEAK AREA IN EASTERN PARÁ STATE.
ABSTRACT This study aims to generate the diagnosis and spatial variability maps of soil fertility attributes, as well as teak (Tectona grandis L.f.) production through geostatistics. The study was conducted on a commercial farm in the municipality of Capitão Poço, state of Pará, Brazil. Soil and yield data were collected from 155 sampled georeferenced poi

9. STRESS, DISPLACEMENT JOINTS OF GMELINA ARBOREA AND TECTONA GRANDIS WOOD WITH METAL PLATES, SCREWS AND NAILS FOR USE IN TIMBER TRUSS CONNECTIONS
ABSTRACT In countries like Costa Rica, there is an interest in developing wooden trusses in a versatile and light way. However, there is a key aspect in the behavior of truss connections in this product. Therefore, the present study determines the structural behavior of the truss connections and the displacement, the resistance, the stiffness values and the

10. Dominant Height Growth in Tectona grandis Plantations in Mato Grosso, Brazil
ABSTRACT Tectona grandis (teak) plantations have gained increased interest in recent decades in Brazil, bringing about the need for acquiring information regarding the growth and productive potential. The present work aims to evaluate the growth of dominant height in teak at various locations in the state of Mato Grosso, midwest Brazil. For this purpose, six

12. Occurrence of Tectona grandis Stem Injury Caused by Cornitermes cumulans Termite
ABSTRACT Termites of the species Cornitermes cumulans (Kollar, 1832) were observed causing injuries in the stem of Tectona grandis in commercial forest plantations in Cáceres, Mato Grosso state, Brazil. C. cumulans forms galleries below the bark, at the heartwood/sap-wood interface of 1.8 years-old trees. This is the first occurrence of this type of injury
