    Effects of varied soil nitrogen supply on Norway spruce (Picea abies [L.] Karst.)

    During a seven-month period the effect of different nitrogen (N) availability in soil on growth and nutrient uptake was studied in three-year-old Norway spruce (Picea abies [L.] Karst.) trees. The plants were gro...

    Effects of varied soil nitrogen supply on Norway spruce (Picea abies [L.] Karst.)

    The response of carbohydrate metabolism in 3-year-old Norway spruce plants to an increased amount of nitrogen supply to a N-poor forest soil was investigated in a pot experiment. After 7 months of treatment we...

    Sucrose phosphate synthase in leaves of mistletoe: its regulation in relation to host (Abies alba) and season

    Sucrose-phosphate synthase (SPS; E.C. 2.4.1.14) was studied in 1-year-old leaves of the xylem-parasitic mistletoe (Viscum album L.), growing on Abies alba. Glucose-6-phosphate served as an allosteric activator o...
