“…On the other hand, vessel proportion was negatively correlated to tension wood proportion. These findings are in good agreement with previous findings for eastern cottonwood [41].…”

“…In tension wood, the S3 layer of the secondary wall is replaced by the thick cellulosic layer known as the gelatinous fiber layer inside the lumen of the fiber. Kaeiser and Boyce [41] reported that gravitational stimulus generally induces the formation of gelatinous fibers, which modify the anatomical characteristics of other elements of wood, such as modifications in the size of rays, vessels, and fibers in Populus deltoides.…”

This study aims to understand the phenotypic and genotypic correlations among wood anatomical, physical, and mechanical properties of hybrid poplar clones. Samples were taken from seven clones grown on three sites in Southern Quebec, Canada. Five trees per clone were randomly sampled from each site to measure anatomical (fiber length, fiber proportion, vessel proportion, fiber wall thickness, tension wood), physical (basic density, volumetric, longitudinal, tangential, and radial shrinkage), and mechanical wood properties (flexural modulus of elasticity (MOE), modulus of rupture (MOR), ultimate crushing strength parallel to the grain). The observed phenotypic and genotypic correlations between these wood properties were moderate to strong, except for fiber length and vessel proportion. Genotypic correlations for all wood properties were higher than for corresponding phenotypic correlations. Furthermore, fiber length showed weak correlations, whereas, vessel proportion showed strongly negative correlations with all other properties. Strong correlations were also found among fiber proportion, fiber wall thickness, basic density, and mechanical properties. Furthermore, results from this study show close genotypic and phenotypic correlations between fiber proportion, fiber wall thickness, and wood density, which consequently affect the mechanical performance of wood products. These findings indicate that there is a substantial opportunity to improve wood quality by selecting several wood properties for different end uses.

“…In this case, morphological factors are not the best criterion to take into account in poplar plantations in order to produce wood with lower values of TW. Similar results have often been observed by other authors in the genus Populus [19,22,23] Isebrands and Bensend [19] put forth the assumption that the cambium of this species would be particularly sensitive to the stimuli involved in the formation of TW. Figure 4 presents the longitudinal distribution of TW.…”

-The main wood quality problem affecting poplar trees is tension wood occurrence associated to end-splits after felling, distortions of products, woolly wood, etc. The objective of this study was to estimate the occurrence of tension wood by using the external shape of the stem and the 3D distribution of annual growth rings. This paper is the first of two papers and presents the inter-clonal and intra-tree tension wood variability. A clear clonal-effect was observed on tension wood area percentage (I-MC>I214>Luisa Avanzo). The clone with the best tree morphology (I-MC) showed the highest percentage of tension wood (15.3%). Concerning the intra-tree variability, tension wood extent increased significantly at the tree base (< 30-50 cm). In the radial direction of the stem, the percentage of tension wood showed an U-shape distribution. The first peak, close to the pith, corresponds to the "establishment growth period" during the open growth and the second peak, close to the bark corresponds to the "competition growth period". tension wood / poplar / variability / cultivar / secondary growth Résumé -Présence de bois de tension dans trois variétés de Populus × euramericana. Partie I : Variabilité inter-clonale et intra-arbre du bois de tension. Le principal problème de qualité affectant les peupliers est la présence de bois de tension associée aux fentes à l'abattage, aux déformations des sciages, ou au bois pelucheux… L'objectif principal de ce travail est d'estimer la distribution du bois de tension à partir de la forme détaillée de l'arbre et de son empilement de cernes en 3D. Cet article est le premier d'une série de deux, où nous présentons la variabilité inter-clonale et intra-arbre du bois de tension. L'analyse de la variabilité du pourcentage surfacique de bois de tension met en évidence un fort effet clone (I-MC>I214>Luisa Avanzo) et montre aussi que le clone avec la meilleure conformation morphologique (I-MC) présente la proportion de bois de tension plus élevée (15.3 %). En ce qui concerne la variabilité intra-arbre, la proportion de bois de tension présente une augmentation significative à la base de l'arbre (< 30-50 cm). Dans la direction radiale, la distribution du bois de tension présente une structure bi-modale en forme de « U ». Le premier mode du côté de la moelle correspondrait à une phase de croissance libre, dite phase « d'établissement » et le second du côté de l'écorce à une phase de recherche de la lumière dite « phase de compétition ». bois de tension / peuplier / variabilité / cultivar / croissance secondaire

“…5a). In the previous studies, there was a general agreement that tension wood contained a lower vessel proportion than normal wood [9,27,42,47,55], except for Kaeiser and Boyce [29] and Kroll et al [34], who reported opposite results. The decreased vessel proportion in tension wood could be partially explained by the auxin concentration.…”

-Six inclined poplar I-69 (Populus deltoids cv. I-69/55) trees were collected for studying the influence of growth stress level on wood properties. Growth stress indicator (GSI) was measured at eight positions around the periphery of each trunk at breast height and corresponding wood samples were obtained. Wood anatomical, physico-mechanical and chemical characteristics were measured, including cell diameter, fibre length, double wall thickness excluding the gelatinous layer, lumen diameter after gelatinous layer removal, proportion of wood tissues, basic density, FSP, MOE, compressive strength, shrinkage and chemical composition. Each property was regarded and discussed in relation to the growth stress level. Populus deltoids
