Impact of coppice and high stem management on Eucalyptus wood quality. European Journal of Wood and Wood Products, 14 p.

Résumé : Coppicing, a well-studied forestry management system, offers significant productivity and economic benefits to plantations. This study aimed to assess the growth and wood quality differences in ten Eucalyptus genotypes, for example, E. grandis x E. urophylla (G3, G4, G5, G6, G8, G10, and G13), E. urophylla (G12), E. saligna (G14), and E. grandis x E. camaldulensis (G16) at three years old under high stem and coppice regimes, considering stem quantity variations. Six trees per clone were sampled in both regimes, with coppice trees having either one or two stems. Various wood and bark properties, including basic density, biomass estimation, pith eccentricity, and heartwood percentage were evaluated. Clone G12 showed the highest increment average volume among the treatments, while clones G14 and G16 had the lowest performances across all management regimes. Under high stem and coppice management, the clones show basic wood density ranging from 485 to 393 kg m-3 and 482 to 405 kg m-3, respectively. Generally, trees grown under the coppice regime produced more heartwood. Under the two-stem coppice regime, 90% of the clones showed greater pith eccentricity in their basal discs. Pith eccentricity varied significantly among clones, with coppice (especially with two stems) showing greater eccentricity compared to high stem management. Overall, wood properties did not significantly differ between high stem and coppice management for the evaluated Eucalyptus clones at three years old, except for pith eccentricity, which favored coppice with two stems. This study highlights the potential benefits of coppicing for specific wood quality traits in Eucalyptus plantations.
