Photosynthetic capacity, respiration and water use efficiency in Scots pine stands,cation and nutrient imbalance in particular in conifers: Many of publications refer to this phenomenon (e.g. Ulrich and Matzner, 1983; Ulrich ., 1984; Lange ., 1985; Schulze ., 1989; Führer ., 1993; Heber ., 1994; other quotations ibid.). This were mainly short-term fumigation experiments, which cou

Estimating fine root production of Scots pine stands,). A substantial part of the tree’s overall carbon economy is represented by the root system. A thorough investigation of root requirements must include tissue synthesis, maintenance costs of the roots and costs of the symbionts over the lifetime of the roots (Eissenstat, 1992). A considerable propo

Mycorrhizal morphotypes of Scots pine,95). In the presence of mycorrhizae litter decomposition is faster and release of nutrients from the litter is higher than in the absence of mycorrhizae (Zhu and Ehrenfeld, 1996). Mycorrhizal fungi seem to play a role in the breakdown of humus, where N and P are largely present in organic forms (Ben

Decomposition of needle-, herb-, root-litter, and Of-layer-humus in three Scots pine stands, to plants (e.g. Bocock and Gilbert, 1957; Falconer ., 1933; Gustafson, 1943; Lunt 1935; Minderman, 1968; Shanks and Olson, 1961; Witkamp and Olson, 1963). Climatic conditions and litter quality greatly influence the process of litter decomposition (Couteaux ., 1995; Fog, 1988). Concerning the litte

Seasonal variability of organic matter and N input with litterfall in Scots pine stands,ecorded by monthly collections at three sites of historically different air pollution and fertilization impacts. Furthermore, seasonal growth dynamics, biomass production and litter (= necromass) input to the forest floor from the ground vegetation was analysed in detail. The ground vegetation bioma

Synopsis of the ecological SANA investigations. An integrated analysis of the results,tions over the entire lifetime of the stand. If it is used as an indicator for forest productivity, however, several uncertainties have to be considered. Firstly, the diameter increase is only proportional to the stem wood production if the tree mortality and the heightdiameter-relation of the trees
