Peeling of Poplar : Cultivars and Forest Stations Effect on Veneer Quality
Résumé
In order to assess the quality of some new cultivars of poplar introduced in
France, ten cultivars (five well known by professional and five promising new
ones) coming from 4 different types of forest stations have been sampled. Two
logs have been harvested per station and per cultivar. Peeling tests have been
then performed on eighty trees: forty peeled in 1.4 mm thick, forty in 3 mm
thick. Veneer quality has been evaluated measuring curl-up, surface quality
(roughness, woolly surfaces), thickness variation and lathe checking. These
tests show that it is absolutely not necessary to adapt peeling parameters to the
different cultivars and according their forest stations.
