Damage to Pinus contorta in northern Sweden with special emphasis on pathogens
During a nine-year-period ca. 100 provenances of Pinus contorta were investigated annually with respect to different kinds of damage. primarily by parasitic fungi. Damage to Pinus contorta occurred mainly during the first ten years after planting. northern provenances of Pinus contorta were generall...
