Compression wood in conifers (Compression Wood)

Darker compression wood revealedSummary

This programme examined the mechanisms of compression wood formation and evaluates how the properties of the raw material in conifers influence the performance of construction timber quality.

Research objectives   

The overall objective of the programme was to obtain long-term improvement in the quality of softwood timber products in terms of mechanical properties (strength and stiffness) and geometrical stability (warp, distortion) related to the occurrence of compression wood.  The programme aimed to compile an overall evaluation of the impact of compression wood on the utilisation of softwood timber and suggest solutions to minimise this impact both at the silvicultural and the processing levels. It also incorporated the effect of compression wood into existing tree growth, yield and wood-quality models.
