Influence of pruning on wood characters in hybrid aspen

Autor: Rytter, Lars, Jansson, Gunnar

Publikováno v: Silva Fennica, Vol 43, Iss 4 (2009)

Fast-growing hybrid aspens (Populus tremula L. x P. tremuloides Michx.) are currently of great interest in Sweden since they can produce biomass at high rates and, at the same time, can be used to produce higher value wood products. This study focuse
