Variation of lignans in Norway spruce (Picea abies [L.] Karst.) knotwood:Within-stem variation and the effect of fertilisation at two experimental sites in Finland
Lignan concentrations in Norway spruce (Picea abies [L.] Karst.) knotwood were studied in two long-term nitrogen fertilised experimental sites: a boreal site (66°5′N, 27°07′E) close to the Arctic tree line in northern Finland and a boreal site (61°10′N, 26°03′E) in southern Finland. Altogether 20 ma...
