THE ASSOCIATION BETWEEN CELLULOSE CRYSTALLITE WIDTH AND TENSION WOOD OCCURRENCE IN EUCALYPTUS GLOBULUS

摘要: The association between cellulose crystallite width and the occurrence of tension wood was assessed for Eucalyptus globulus Labill., a commercially important plantation hardwood species. Crystallite (uncorrected instrumental broadening) determined from X-ray diffraction patterns collected on SilviScan-2, an instrument developed rapid assessment microstructure. Comparisons widths were made using 66 samples normal selected randomly one tree known to have abundant wood. Tension found significantly wider crystallites than mean 3.6 nm 3.2 consistent with those reported in previous studies, allowing experimental broadening equivalent about 0.5 this work. This study demonstrates that SilviScan-2 is useful detection solid such as increment cores.
