To investigate the impact of organic N compounds for inorganic nitrogen uptake in the rhizosphere, we fed ammonium nitrate with or without amino acids (i.e., glutamine or arginine) to the roots of non-mycorrhizal beech (Fagus sylvatica L.) seedlings under controlled conditions at different levels of
To assess the physiological performance of drought-sensitive European beech ( Fagus sylvatica L.) under the dry Mediterranean climate prevailing at its southeastern distribution limit in Europe, we analyzed seasonal changes in carbon, nitrogen and water balance of naturally grown adult trees. We
The amino acid contents of sun and shade leaves of the copper beech are significantly different. On the basis of dry matter, the concentration of the majority of amino acids is higher in shade leaves. Only the concentrations of proline, valine, histidine and arginine are about 30% lower compared
