Longitudinal growth strain as a log and wood quality predictor for plantation-grown Eucalyptus nitens sawlogs
journal contribution
posted on 2023-05-19, 05:23 authored by Valencia, J, Christopher HarwoodChristopher Harwood, Washusen, R, Morrow, A, Wood, M, Peter VolkerPeter VolkerPeripheral longitudinal growth strain (LGS) was measured on a total of 81, 22-year-old pruned Eucalyptus nitens trees from five thinning treatments in a plantation thinning trial in Tasmania. Growth strain data were gathered at breast height on each tree using the CIRAD-Forêt method. The effects of thinning treatment and tree diameter on LGS and its relationships to solid-wood traits determined in a processing trial were examined. LGS was significantly higher in the direction of the prevailing wind and was not significantly affected by either thinning treatment or tree diameter. An index of log end splitting was positively related to tree diameter, sawlog position (upper/lower), and LGS, which explained up to an additional 20% of the variance after tree diameter and log position were accounted for in a linear regression model. High LGS and log end splitting were significant indicators of increased board end splitting.
