Visual and machine grading of larch (Larix decidua Mill.) structural timber from the Italian Alps
The present paper focuses on the main results of an inter-regional project (Bois-lab) aimed at determining the settings of various machines for grading larch (Larix deciduaMill.) timber from Italian and French Alps, that can now be graded for structural use and CE marked according to EN 14081-1. In particular it reports the differences registered between visual and machine grading on 261 larch ...
متن کاملVariability in Larch (Larix Decidua Mill.) Tree-Ring Growth Response to Climate in the Polish Carpathian Mountains
The climate–growth relationship of larch (Larix decidua Mill.) in the Polish Carpathian Mountains was studied. We explored the spatial variability of the common signal observed in larch tree-ring growth, distinguished regions with uniform tree-ring growth patterns (dendrochronological signal), and determined the climatic factors that are particularly important for the growth of larch in this ar...
متن کاملReduction of phenolics in mycorrhizas of Larix decidua Mill.
Soluble and cell-wall-bound phenolics in mycorrhizas of Larix decidua-Laccaria amethystea and in nonmycorrhizal fine roots of larch grown in sterile culture were analyzed by HPLC. The soluble phenolics p-hydroxybenzoylglucose, p-hydroxybenzoic acid glucoside, picein, catechin, and epicatechin were identified in nonmycorrhizal fine roots. The same phenolics also occurred in mycorrhizas, but only...
متن کاملCarbon dioxide exchange of larch (Larix gmelinii) cones during development.
Larch (Larix gmelinii (Rupr.) Rupr.) cone scales are green, but little is known of their photosynthetic role in cone development or about how they differ in gas exchange characteristics from needle leaves. In contrast to leaf photosynthesis (Pleaf), we found that stomatal regulation of cone photosynthetic rate (Pcone) was marginal because the photosynthetic carbon came from internal recycling o...
متن کاملDynamics of heartwood formation and axial and radial distribution of sapwood and heartwood in stems of European larch (Larix decidua Mill.)
The study was an attempt to determine the dynamics of heartwood formation and the radial and axial distribution of sapwood and heartwood in stems of European larch (Larix decidua Mill.) representing the dominant stand according to Kraft. Correlations were found between the rate of heartwood formation and the social class of tree position in the stand, the age of trees, forest site type and heig...
