“…Compared to Pasaribu et al (2012), the bending (MOE and MOR) value was higher than that of them. Furthermore, den- sity, microfibril angle, knots, fiber length, fiber spiral, moisture content and temperature of environment include as factors that also affect the MOE values (Huang et al, 2003).…”

“…Corewood MoE is mostly determined by MFA, but this property is expensive and time consuming to assess (Huang et al, 2003). Acoustic tools -based on stress wave, ultrasound velocity or sonic resonance -provide an easy estimation of MoE, that can be used for log segregation and tree selection (Lindström et al, 2002).…”

“…Acoustic tools -based on stress wave, ultrasound velocity or sonic resonance -provide an easy estimation of MoE, that can be used for log segregation and tree selection (Lindström et al, 2002). Acoustics can be used for screening at a very early age and be related to a number of properties like MoE, dimensional stability, fiber length, etc (Huang et al, 2003).…”

Abstract• This article reviews the theoretical basis for indirect selection -where early selection is an example -and how correlated response is calculated.• The review is followed by a description of issues as to the choice of selection criteria that could explain the lack of substantial progress on breeding for wood quality. These include: the autoregressive nature of selection criteria, overemphasizing the importance of basic density as selection criterion, ignoring age-related trends of wood properties, using rotation age rather than technical thresholds as objective traits and ignoring that not all grades have identical marginal economic value.• Three data sets are either analyzed for the first time or reanalyzed under different assumptions, to explore the importance of these criticisms.• Finally, the use of critical value thresholds as very early selection criteria is suggested and discussed in the context of improving intrinsic corewood quality. Mots-clés :rigidité / sélection précoce / caractère seuil / Pinus radiata Résumé -Sélection très précoce pour les propriétés du bois massif : détection précoce des individus les plus performants.• Cet article passe en revue les bases théoriques des méthodes de sélection indirecte -parmi lesquelles figure la sélection précoce -et la manière dont le gain corrélé est calculé.• Cette revue est suivie d'une description des problèmes liés au choix des critères de sélection et qui pourraient expliquer le manque de progrès substantiel suite à l'amélioration pour les propriétés du bois. Ceux-ci incluent l'auto-corrélation des critères de sélection, l'exagération de l'importance de la densité comme critère de sélection, l'oubli de l'évolution des propriétés du bois avec l'âge cambial, l'utilisation de l'âge de révolution comme caractère-cible plutôt que des seuils techniques et l'oubli que toutes les classes de produits n'ont pas la même valeur économique marginale.• Trois jeux de données ont été soit analysés pour la première fois soit ré-analysés sous différentes hypothèses pour explorer l'importance de ces critiques.• Enfin, l'utilisation de seuils critiques comme critères de sélection très précoce est suggérée et discutée dans le cadre de l'amélioration intrinsèque de la qualité du bois juvénile.

“…All these factors are refl ected in the acoustic properties of wood. They should be taken into account in the choice of wood for the production of musical instruments (Wegst, 2006), in using sound propagation speed to evaluate the wood quality (useful for construction) and for the production of pulp (Huang et al, 2003).…”
