Variations of Wood Properties of Birch (betula Pendula Roth) From a 23-year Old Seed Orchard
Year: 2020
Type: article
Abstract: This work presents the results of selected wood properties in birch trees grown on a provenance experiment plot established as a seed orchard.The study concerned: basic density, oven-dry density and compression strength along the grain at a moisture content of 0% and at moisture content above fiber saturation point.Analyses were performed on 971 wood samples collected from 28 trees at the level of breast height.It was found high variability for diameter of breast height (22%) and relatively low for basic density (9%) and oven-dry density (11%).Average basic density was 446.5 kg .m -3 and average oven-dry density was 537.9 kg .m -3 .The compression strength at 0% moisture content was four times higher (65 MPa) than the strength at moisture content above the fiber saturation point (16.6 MPa).Most of clones had similar properties within the limits of statistical errors, but a few clones exhibited statistically significant low value.
