Wound wood formation in Eucalyptus globulus and Eucalyptus nitens: anatomy and chemistry

The wound-associated wood that developed 17 months following artificial xylem injury in Eucalyptus globulus (Labill) and Eucalyptus nitens (Maiden) was examined anatomically and chemically. This new tissue located immediately adjacent to the wound site and termed “wound wood” was highly variable consisting of callus, altered wood of increased parenchyma density, and dark extractives, visible to...

Leaf water relations of Eucalyptus globulus ssp. globulus and E. nitens: seasonal, drought and species effects.

In August 1990, a 2-ha plantation was established in an area where rainfall (about 515 mm year(-1)) was insufficient to meet evaporative demand. On nine occasions between September 1991 and April 1993, pressure-volume curves were constructed for irrigated and rainfed Eucalyptus globulus ssp. globulus Labill. and E. nitens (Deane and Maiden) Maiden trees. During the experiment, rainfed trees exp...

Eucalyptus Globulus

"The authentic facts, relating to the remarkable power of the Eucalyptus Globulus in drjing marsh lands and rendering them healthy, are such as to deserve serious and general attention. It appears to be certain that where the Eucalyptus prospers intermittent fever disappears. This tree grows with incredible rapidity, absorbs ten times its own weight of water in twentyfour hours, and spreads thr...

Eucalyptus globulus wood fractionation by autohydrolysis and organosolv delignification.

This work provides an assessment on the fractionation of Eucalyptus globulus wood by sequential stages of autohydrolysis (to cause the solubilization of hemicelluloses) and organosolv pulping (to dissolve lignin, leaving solids enriched in cellulose). With this approach, valuable products (hemicellulose-derived saccharides, sulphur-free lignin fragments and cellulosic substrates with low conten...

Genetic Variation in the Chemical Components of Eucalyptus globulus Wood

Despite the ecological and economic importance of lignin and other wood chemical components, there are few studies of the natural genetic variation that exists within plant species and its adaptive significance. We used models developed from near infra-red spectroscopy to study natural genetic variation in lignin content and monomer composition (syringyl-to-guaiacyl ratio [S/G]) as well as cell...
