Genetic Variation In Wood Density And Its Measurement Using The Resistograph

For the study, 12 mm increment cores were collected from 14 full-sib families of loblolly pine generated by a diallel mating design. Randomized complete blocks with six replications field design was used in four test sites located in South Carolina. Each full-sib family was represented by six trees in row plots. Wood basic density was determined for 2016 trees applying standard volumetric method. The same trees were drilled with the Resistograph. Individual ring density, ring width, early and late wood were determined scanning the core increments by the xray. Relationships between volumetric, x-ray scanning profiles and the Resistograph profiles were detected. Keywords: Loblolly pine, basic wood density, x-ray scanning, resistograph
