Forest plantations, particularly high-density planted stands, are considered to be more prone wind damage compared naturally regenerated stands. The resistance (mechanical stability) of plantations can, however, improved by close-to-natural management, for example, combining pioneer and shade-tolerant species. Presumably, the stability such stands would enhanced reduced competition canopy trees...

Abstract A chronosequence approach was applied to evaluate the effects of silver birch succession on soil organic matter (SOM). The studies covered five plots (arable field [AF], fallow [FA] and three stands aged 8, 33 40 years), all located in same complex Brunic Arenosols central Poland. O horizons soils were sampled analysed using standard procedures science. It found that accompanied by dyn...

The knowledge of pollen sensitivity and tolerance to stress factors such as air pollution is important for forest sustainability, ensuring the most efficient production with highest benefits lowest resource losses. This study intended evaluate influence common pollutants in four trees species, Betula pendula Roth, Corylus avellana L., Acer negundo L. Quercus robur through a comparative analysis...

The research presents the first results of aluminium speciation analysis in aqueous extracts of individual plant parts of Betula pendula and soil samples, using High Performance Ion Chromatography with Diode Array Detection (HPIC-DAD). The applied method allowed us to carry out a full speciation analysis of aluminium in the form of predominant aluminium-fluoride complexes: AlF(x=2,3,4)(3-x) (fi...

The influence of major nutrients’ reserves (available to plants) – nitrogen (N), phosphorus (P), potassium (K) in the top 25-cm layer soil on Karelian birch (Betula pendula Roth var. carelica (Mercl.) Hämet-Ahti) with non-figured and figured wood via antioxidant enzymes’ activity was investigated. analysis sites area where trees varying degree intensity were growing carried out. cambial zone sa...

Abstract We extend the study of economically optimal carbon storage to a previously unexplored forest type, mixed-species size-structured stands. The ecological model applied in is transition matrix with growth functions for boreal Norway spruce ( Picea abies (L.) Karst.), birch Betula pendula Roth and B. pubescens Ehrh.), other broadleaves. broadleaved trees are assumed have no commercial valu...

One-year-old seedlings of silver birch (Betula pendula Roth.) were grown in pots filled with a soil substrate that originated from an area polluted by a phosphate fertiliser factory and characterised by a high soil Al level and low Ca/Al ratio or with a substrate from an area regarded as free from toxic pollution. In addition the effect of fertilisation with a mixture of nutrients was evaluated...
