Abstract
This study is aimed at comparing the final moisture distribution (mean MC and variability) and drying distortions of six Euramerican poplar clones (Populus deltoides x nigra) originating from a multiclonal stand using traditional kiln-drying at low temperature. The selected poplar clones yielded a different final MC after drying, implying the drying schedule needs adaptation per clone or clonal groups. An additional homogenization period of two weeks under ambient outdoor condition lowered the average final MC significantly with 2-3 %. The occurrence of wet pockets is a major concern in drying poplar lumber of which clonal differences have been demonstrated. Density and tension wood proportions are influencing factors to drying deformations (bow and crook). All clones display acceptable values for twist, while none of the clones comply to the demands concerning crook as requested for structural applications. The limitations for bow are only met by the poplar clones "Ghoy" and "Gaver".
