1. ECONOMIC PERFORMANCE OF LOBLOLLY PINE STANDS IN SOUTHERN BRAZIL AS A RESULT OF DIFFERENT CROWN THINNING INTENSITIES1
RESUMO Aproximadamente 1,6 milhões de hectares são cultivados com Pinus no sul do Brasil, principalmente com Pinus taeda L. Mais de um terço dos povoamentos pertencem a produtores de toras independentes, cujos objetivos são maximizar os resultados econômicos. Neste estudo, um experimento de desbastes foi avaliado durante um período de produção de 30

2. Modelagem do crescimento e da produção de povoamentos de Tectona grandis submetidos a desbaste / Modeling growth and production of stands of Tectona grandis
The objective of this study was to construct a model of growth and production, simulate alternative management stands of teak submitted to selective thinning and evaluate the effectiveness of the selective sampling to obtain data for the modeling of growth and production. The Clutter model was adjusted in its ordinary form, and, also, in the modified form, b

3. GROWTH AND YIELD OF Pinus taeda L. IN THE CAMPOS DE CIMA DA SERRA REGION, RIO GRANDE DO SUL. / CRESCIMENTO E PRODUÇÃO DE Pinus taeda L. NA REGIÃO DOS CAMPOS DE CIMA DA SERRA, RIO GRANDE DO SUL.
This thesis was carried through as objective to study the growth and the yield of a stand of Pinus taeda L., implanted in 1987, in an initial spacing of 3 x 2 meters, located in the Farming Farm of the Ipê Ltda, in the city of CanelaRS. This stand was management in high shaft system, with thinning underneath, for the wooden yield of great dimensions. To rea

5. Avaliação técnica e econômica do corte de Pinus com harvester / Technical and economical evaluation of the cut of Pinus with harvester
In the Brazilian forest sector, several companies use modern technologies at the production phases. Specially in the case of the planted forests, those technologies are used from the obtainment of the seedlings until the delivery of the wood in the industry yards. The harvest has a distinguishable position in composing the final cost of the wood. In some cas

6. EFFECT OF THE THINNING INTENSITY IN THE DENDROMETRIC AND TECHNOLOGICAL CHARACTERISTICS OF THE WOOD OF Eucalyptus grandis Hill ex Maiden / EFEITO DA INTENSIDADE DE DESBASTE NAS CARACTERÍSTICAS DENDROMÉTRICAS E TECNOLÓGICAS DA MADEIRA DE Eucalyptus grandis Hill ex Maiden
This study was understaken to evaluate the effect of different thinning intensities in the dendrometric and technological characteristics of the wood of Eucalyptus grandis at 14 years of age. There was analyzed a thinning experiment, located in the northern coast of Rio Grande do Sul installed in randomized blocks, with four treatments (T1 = 1638 trees/ha; T

7. Modelagem e avaliação econômica de plantações de eucalipto submetidas a desbastes / Modeling and economic evaluation of plantations of eucalypts submitted to thinnings
The objective of the present work was to evaluate the efficiency of the Clutter model (1963) to predict the growth and yield of thinned stands of eucalypts and to economically evaluate various thinning intensities. The study was developed with data of an essay about thinnings established in stands of eucalyptus belonging to the Copener Florestal Ltda., locat
