Abstract : 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 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
