Altitudinal transfer of Norway spruce (Picea abies (L.) Karst.) provenances in northern Sweden
Provenances of Norway spruce (Picea abies (L.) Karst.) are generally transferred from lower latitudes and elevations to areas where the local seed production is insufficient and with the goal to increase volume production because growth cessation in the fall is induced later in northward transferred...
