Effects of soil acidification and liming on biomass responses and “free” Al, Ca, K, Mg, Mn and P contents of mycorrhizal roots of mature Norway spruce (Picea abies [L.] Karst.) were studied at Höglwald Forest in Southern Germany. At the untreated site, mycorrhizal root biomass was lower in the acid humus (pH = 3.3) than in the less acid upper (0–5 cm) mineral soil (pH 4.1). Mycorrhizal roots from...
Effects of soil acidification and liming on the activities of three enzymes of the carbohydrate metabolism and the quantities of two of the major organic acids of mycorrhizal roots of Norway spruce (Picea abies [L.) Karst.) were studied at Höglwald Forest in southern Germany. The enzymes investigated were glucosephosphate isomerase, pyruvate kinase and 6-phosphogluconate dehydrogenase. The organic...
