Abstract

- A sample of 162 trees was harvested from a 36-year-old Scots pine (Pinus sylvestris L.) progeny trial to evaluate correlations between early measurements of branch diameter, and other stem and branch traits, with sawn timber traits, and hence their potential utility for predicting wood quality. The sample trees were assigned to three genetic groups of small, medium and large branch diameter, based on parental breeding values. Bottom logs were cut and sawn, and several important traits for the visual quality of the boards were assessed. Phenotypic correlations were then estimated between these traits and measurements of the height, diameter, branch diameter, branch angle, stem crookedness, number of branches and grain angle under bark of the corresponding trees when they were 16 and 36 years old. The diameter of the coarsest knot in the board was correlated with the branch diameter at the age of 16 years (0.50), and there were significant differences in this trait among the genetic branch diameter groups. In addition, the board twist was correlated with the grain angle under bark at the age of 36 years (0.54). Thus, the field assessments of branch diameter and grain angle under bark show relevance for the visual quality of centrally sawn small timber.
