1. 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

2. Morphology and infection process of Olivea neotectonae in teak leaves
RESUMO: A ferrugem, causada pelo fungo biotrófico Olivea neotectonae, destaca-se como uma doença importante nas plantações de teca no Brasil. Considerando a importância atual dessa ferrugem e a necessidade de obter informações básicas adicionais sobre seu agente causal para melhor manejo da doença, o presente estudo teve como objetivo analisar a mor

3. 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

4. Dendrometric evaluation of a clonal population of Tectona grandis in forest-livestock system
RESUMO: A produção de madeira de Tectona grandis (teca) em sistemas integrados com pecuária ou agricultura demonstra alta perspectiva de retorno financeiro. Entretanto, estudos sobre o desenvolvimento da teca ainda são escassos, principalmente na região norte de Mato Grosso. O objetivo do trabalho foi avaliar o crescimento das variáveis dendrométrico

5. First Report of Heterotermes longiceps (Blattodea: Rhinotermitidae) Termite in Teak Plantations
ABSTRACT Heterotermes longiceps termites was observed causing injuries in Tectona grandis plants in a forest plantation in Cáceres, Mato Grosso, Brazil. H. longiceps caused galleries below the bark, at the heartwood-sapwood interface, from the beginning of the root until approximately 1 m height tall and very infested plants has died. This is the first repo

6. Canonical Correlation Analysis Between Growth and Nutrition in Teak Seedlings
RESUMO Determinar a relação existente entre os nutrientes e o crescimento das plantas implica em estudos e a aplicação de análise estatística capaz de explicar essas interações. Diante disso, estabeleceu-se experimento com doses de N, P2O5 e K2O e seus efeitos nas correlações entre crescimento e os nutrientes em mudas de Tectona grandis, a partir d

7. Deterioration of Teak Wood in Accelerated Decay Test
ABSTRACT The present study aimed to evaluate the biological resistance of teak (Tectona grandis) heartwood and sapwood to the action of Trametes versicolor and Gloeophyllum trabeum fungi in laboratory accelerated decay assays. The mass loss evaluation of the samples was performed periodically. The heartwood presented a higher percentage of extractives and th

8. Influence of Age on the Discrimination of Tectona grandis by VIS/NIR Spectroscopy
ABSTRACT Wood color and properties are variables among and within species, and fast and non-destructive techniques can be applied to their characterization, being also important in wood marketing and quality control. This paper evaluated the influence of age on the discrimination of Tectona grandis L.F. (teak) wood by VIS/NIR spectroscopy. Wood from three ag

9. Effect of Brachiaria Grass on Vegetative Development of Teak
ABSTRACT Invasive plants are a limiting factor for the establishment of planted teak (Tectona grandis L.f.) forests, especially because most of them are planted on Urochloa decumbens Stapf degraded pastures. This study evaluated initial teak development applying different control alternatives for U. decumbens . Treatments were no weed control (T1), continuo

10. Essential Oils for Alternative Teak Rust Control
ABSTRACT The objectives of this study were to evaluate the effect of lemon grass, citronella grass, Mexican-tea and noni essential oils on urediniospore germination of Olivea neotectonae , the agent responsible for rust in Teak (Tectona grandis L.f.); to evaluate the phytotoxic effect of these essential oils on teak seedlings; and to evaluate the use of ess

11. SOIL WATER RETENTION CURVE AND S INDEX AS SOIL PHYSICAL QUALITY INDICATORS FOR INTEGRATED PRODUCTION SYSTEMS
ABSTRACT Assess the physical quality of agricultural soils it is important to establish the management more adequate for plant growth. In this study, the soil water retention curve and S index as indicators of soil physical quality were evaluated in five integrated production systems in the following forestry arrangements: Eucalyptus in a single line, double

12. Efficient and new method for Tectona grandis in vitro regeneration
Abstract The aim of this study was to develop a shoot regeneration protocol for Tectona grandis by examining the effects of pretreatments, regeneration culture medium, adventitious rooting, and acclimatization. The best organogenic potential was achieved when hypocotyls and cotyledonary segments from seedlings germinated on a medium containing TDZ, were cult
