Relevance of wood anatomy and size of Amazonian trees in the determination and allometry of sapwood area [PDF]
Acta Amazonica, 2019 Hydrological processes in forest stands are mainly influenced by tree species composition and morpho-physiological characteristics. Few studies on anatomical patterns that govern plant hydraulics were conducted in tropical forest ecosystems.

DRYING OF SAPWOOD ANALYZED AS AN INVASION PERCOLATION PROCESS [PDF]
Maderas: Ciencia y Tecnología, 2006 The sapwood fibers in green softwood are normally filled - or nearly filled - with free water. This water forms a continuous phase through the narrow bordered pits between fiber lumens. In a drying process water evaporates from the menisci formed at these narrow throats and initially located close to the surface of the wood. As the amount of free water

Sapwood water content of lodgepole pine
, 2010 Breast height sapwood water content fluctuations of lodgepole pine (Pinus contorta var. latifolia Engelm) were studied with the objective of relating them to conducting xylem area, and to environmental and plant variables. Also gamma radiation attenuation was tested as a method for in situ sapwood water content measurement.

Positional differences in the micro- and ultra-structural variations of ray parenchyma cells during the transformation from sapwood to heartwood. [PDF]
Front Plant SciRay parenchyma cells are involved in the initiation of heartwood formation. The position within a ray influences the timing of ray parenchyma cell differentiation and function; however, there is little information concerning the positional influence on ...

Chemical characterization ofPinus halepensissapwood and heartwood
Wood Material Science & Engineering, 2018 ABSTRACTThis paper describes the chemical composition of sapwood (SW) and heartwood (HW) of Pinus halepensis Mill stem. Extractives were first isolated by accelerated solvent extraction and then analysed by gas chromatography-mass spectrometry (GC-MS).

Resin Metabolism in the Sapwood of Pinus radiata [PDF]
Nature, 1963 Carbon-14 produced in nuclear explosions was used as a tracer to examine resin metabolism in Pinus radiata. Annual rings of trees were ground and the resin extracted. The C/sup 12/: C/sup 13/ and C/sup 14/ ratio of each sample was determined. Results indicate that all the resin activity is considerably lower than that of the atmosphere at the time the ...
