Near InfraRed (NIR) spectroscopy can predict cellulose content in ground eucalypt woodmeal, using calibrations developed from the spectra of sets of chemically analysed samples. Most past calibrations have used small sample sets (<100 samples) representing a single stand or region and only one species, making their application to wider populations of samples problematic. A robust, non-destructive prediction capability for eucalypt wood cellulose that works across stands, regions and species would find many applications in tree breeding and resource assessment.
