Structural characterization of lignin in heartwood, sapwood, and bark of eucalyptus
International Journal of Biological Macromolecules, 2019Understanding the distribution and structural features of lignin in heartwood, sapwood, and bark of terrestrial plants is important to optimize the industrial utilization of lignocellulose. In this work, the lignins in heartwood, sapwood, and bark of Eucalyptus urophylla × E. grandis were comparatively studied.

Balsam fir trees established from advanced regeneration following a clear-cut in 1970 were pruned in June 1985 to live crown ratios of 0.6, 0.4, and 0.2 compared with control trees, which had live crown ratios of 0.8. After two growing seasons, we investigated the homeostatic adjustment of these trees to the loss of their foliage.

Sapwood water content of lodgepole pine
2010Breast 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.

Effects of Various Fixing and Storage Fluids on Starch in Sapwood
Stain Technology, 1962Wood material that is to be used for observation of starch content may be stored many months in several plant material fixatives, formalin-acetic-alcohol, formalin-propionic-alcohol, tertiary butyl alcohol, ethyl alcohol, and 5 and 10% aqueous formalin without any apparent deleterious effect on the starch granules Storage of wood in aqueous formalin ...
