In this study, a large number of wood samples from several species of Eucalyptus, including E. grandis, E. urophylla, E. globulus, E. dunnii, E. camaldulensis and their crossing were characterized by pyrolysis-GC/MS method. All the measurements were done directly from the Eucalypus wood samples. S/G ratios were calculated for all guaiacyl and syringyl lignin pyrolysis derivatives. The results w...

Annual tritium exposures were reconstructed using tree cores from Pinus jeffreyi and Eucalyptus globulus near a tritiated water vapor release stack. Both tritium (3H) and carbon-14 (14C) from the wood were measured from milligram samples using accelerator mass spectrometry. Because the annual nature of the eucalyptus tree rings was in doubt, 14C measurements provided growth rates used to estima...

A variety of the Leucaena genus, Leucaena diversifolia, was used for pulp and paper making by kraft and refining processes and a OD(EP)DP bleaching sequence. The same species has been suggested as an energy crop and, in fact, this species used shows a high gross heating value; besides, this variety of Leucaena has appropriate characteristics for pulp and paper making. The holocellulose content ...

The lipid and lignin compositions of woods from the eucalypt species Eucalyptus globulus, E. nitens, E. maidenii, E. grandis, and E. dunnii have been characterized. The lipid composition was analyzed by GC and GC/MS using shortand medium-length high-temperature capillary columns, which allowed the detection of intact highmolecular-weight compounds. Similar lipid compositions were observed in al...

Calibrations of indirect methods for estimating leaf area are usually based on small data sets and are often species-specific and may even be stand-specific. We used the Licor LAI-2000 plant canopy analyser (PCA) as a reference to calibrate leaf area measurements based on hemispherical photography. Ten stands of 6–8 year-old, plantation grown Tasmanian bluegum (Eucalyptus globulus Labill.) in W...
