    Abstract: The reduction of resinous species in Portuguese forest areas has caused constraints to wood industry supplies. Portugal represents the extreme southwest of Scots pine (Pinus sylvestris) natural distribution and large gaps exist in the knowledge of its wood-quality characteristics. Understanding the relationship between these traits is important for recognizing which combination of ...

    The genetic variation of Scots pine in Scandinavia is clinal by latitude as an adaptation to climate. The response is to photoperiod resulting in a large-scale GxE interaction over a north-south gradient. Genetic variation is substantial for all characteristics and mainly additive, although heritabilities in general are low.
