One of the primary purposes forest fire research is to predict crisis situations and, also, optimize rescue operations during fires. The results presented in this paper provide a model Cross-Country Mobility (CCM) brigades areas before or fire. In order develop methodology vehicle mobility wooded area, structure must first be determined. We used Digital Surface Model (DSM) and Elevation (DEM) d...

BACKGROUND AND AIMS The summer annual Impatiens glandulifera can reach 3 m in height within deciduous woodland. The primary objective was to determine if NO(3)(-) accumulation, and hence its osmotic effect, is an important physiological mechanism allowing Impatiens to achieve substantial height under low irradiance. METHODS Stem extension, concentrations of K(+) and NO(3)(-) in leaves and con...

Cork porosity, due to lenticular channels, varied along the stem of Quercus suber L. Lenticular channels’ area, rather than their number, decreased upwards stem. Area decrease was observed regardless tree size and its intrinsic porosity. The cork is radially crossed by defining cork’s natural It has been suggested that porosity decreases from base upwards, but studies on such variation have not...

This study reports the stem volume of 10 Populus genotypes in a randomized split-plot design with different tillage treatments (disking versus sub-soiling) after two years of growth. Height, diameter at breast height (DBH), stem aboveground volume index, survival, Melampsora rust resistance, leaf area index (LAI), chlorophyll content, and foliar nitrogen concentration (Foliar N) were measured t...

Context: Understanding biological processes in forests is necessary to orientate ecosystem management towards potential C sequestration. To achieve this, information is required about changes in forest biomass C pools, including the stem components (bark, sapwood and heartwood). Aims: This study aimed to determine whether there are differences in C concentration in axial and radial directions w...

Terrestrial laser scanning is a powerful technology for capturing the three-dimensional structure of forests with a high level of detail and accuracy. Over the last decade, many algorithms have been developed to extract various tree parameters from terrestrial laser scanning data. Here we present 3D Forest, an open-source non-platform-specific software application with an easy-to-use graphical ...

Plant traits are important indices for regulating and controlling yield ability in soybean varieties. It is important to comprehensively study the quantitative trait locus (QTL) mapping for soybean plant traits, cloning related genes, and marker assistant breeding. In this study, 236 F2 generation plants and a derivative group were constructed by using Jiyu50 and Jinong18, obtained from Jilin P...
