Young beech (Fagus sylvatica L.) and spruce (Picea abies [L,] Karst.) trees, each from two different provenances, were grown in competition in model ecosystems in open-top chambers for four years. The treatments consisted of elevated concentrations of CO, (370 pL L 1 versus 590 pL L“1), increased wet deposition of nitrogen (7 versus 70 kg N ha~' y ')• and two different forest soils (acidic versus calcareous). Chloroplast pigments in darkand light-adapted leaf material sampled in the last year… CONTINUE READING
