1. The management of orthotropic stems modulates the photosynthetic performance and biomass allocation of productive plants of Arabica coffee
ABSTRACT Due to the possibility of enhancing the physiological responses by modulating the architecture of coffee trees, the objective of the study was to analyze the leaf gas exchanges and biomass allocation of Arabica coffee cultivated with different numbers of orthotropic stems. The experiment was carried out in a plantation located in Santa Teresa-ES, Br

3. WOOD QUALITY OF Pinus patula Schltdl & Cham FOR THE PULP PRODUCTION
RESUMO O setor de polpa celulósica de fibra longa tem como base de suprimento as madeiras de Pinus taeda e P. elliottii e compete por essa matéria-prima com outros setores madeireiros. O estudo objetivou avaliar a qualidade da madeira de Pinus patula para a produção de polpa e papel. Árvores com 14 anos foram obtidas de um plantio localizado em Ponte Al

4. Composición y estructura del dosel de sombra en sistemas agroforestales con café de tres municipios de Cundinamarca, Colombia
Abstract The composition and structure of the shade canopy in coffee plantations of the municipalities of Tibacuy, Pacho and San Juan de Rioseco, in Cundinamarca, Colombia, were studied. Fifteen (15) farms in each municipality were selected and, in each farm, a coffee plantation (Coffea arabica cv. Castillo), in which it was established a plot of 1000 m2, wh

5. Stem Modelling of Eucalyptus by Terrestrial Laser Scanning
ABSTRACT The objective of this work was to obtain the stem volume from 3D-cloud points generated by terrestrial laser scanning in Eucalyptus stands. The processing started with using algorithms for tree detection in plantation (TDP) and stem filtering (Filter Dmax). Then, the acquisition of the total height was made semi-automatically and tridimensional mode

6. Besouros crisomelídeos em plantios de eucalipto na Zona da Mata Mineira
Resumo A cultura do eucalipto tem crescido nos últimos anos na Mesorregião da Zona da Mata Mineira. Entretanto, apesar dos fatores favoráveis para o estabelecimento de plantios de eucalipto nessa região, a ocorrência de besouros desfolhadores da família Chrysomelidae pode inviabilizar tais projetos florestais. Portanto, o objetivo deste trabalho foi re

7. Distribuição do diâmetro de copa e diâmetro quadrático de Araucaria angustifolia e Pinus taeda
Resumo As funções de densidade de probabilidade têm várias aplicações florestais, entre as quais o tratamento de dados biométricos e uso em modelagem. O objetivo deste estudo foi verificar qual função densidade de probabilidade melhor se ajusta ao diâmetro de copa (dcopa) e ao diâmetro quadrático (dq), e também analisar o efeito dessas variávei

8. Soil quality indicators under management systems in a Quilombola community in the Brazilian Cerrado
ABSTRACT: Soil management systems exert different effects on soil attributes, especially on the organic matter content, and, consequently, the soil aggregation. The aim of this study was to evaluate the impact of different land uses practiced by quilombola family farmers on water stable aggregates, glomalin and organic carbon in soil aggregates. Soil samples

9. RAINFALL WATER QUALITY UNDER DIFFERENT FOREST STANDS
ABSTRACT The rainfall-forest canopy interaction can impact on the chemical and physical rain-water features and is expected that different forests will have different effects on throughfall rain-water quality parameters. This study aimed (i) to compare chemical and physical rain-water quality variables observed in both gross precipitation and throughfall mea

10. Edaphic and Topographic Factors and their Relationship with Dendrometric Variation of Pinus Taeda L. in a High Altitude Subtropical Climate
ABSTRACT The study of the relationships between the yield potential of forest stands and the conditions offered for plant development is fundamental for the adequate management of the forest when aiming at sustainable high yields. However, these relations are not clear, especially in commercial forests, on rugged terrain where relationships between the lands

11. Vegetation Cover Development Resulting from Different Restoration Approaches of Exploited Mines
ABSTRACT The vegetation cover development is an essential step towards the restoration of the ecosystems. In this work, we applied remote sensing to evaluate the temporal development of vegetation cover on exploited mines revegetated with five approaches: natural regeneration, tree plantation, cultivation of trees + herbs, topsoil replacement + tree plantat

12. Intercropping Acacia mangium stimulates AMF colonization and soil phosphatase activity in Eucalyptus grandis
ABSTRACT: Arbuscular mycorrhizal fungi (AMF) are very important to plant nutrition, mostly in terms of acquisition of P and micronutrients. While Acacia mangium is closely associated with AMF throughout the whole cycle, Eucalyptus grandis presents this symbiosis primarily at the seedling stage. The aim of this study was to evaluate the dynamics of AMF in the
