A Comparison of Radial Wood Property Variation on Pinus radiata between an IML PD-400 ‘Resi’ Instrument and Increment Cores Analysed by SilviScan

Mature age Pinus radiata D. Don trees were sampled across nine sites in northern New South Wales, Australia, that expected, based on site quality and inventory metrics, to exhibit significant variation productivity wood quality. Twenty per harvested 13 mm diameter, pith-to-bark increment cores extracted from three eight of the for SilviScan analysis. Outerwood collected all basic density measurement. The same also using an IML PD400 (Resi) instrument. Radial mean properties derived Resi traces found correlate strongly with data analyses cores. Resi-derived 10 radial segments was correlated measures averaged at similar intervals.
