We measured the initial growth performance of a young plantation of European beech treated with a brassinosteroid compound prior to planting and compared it with a control treatment: we assessed heigh...
Fagus sylvatica Linnaeus (European beech), the ecologically and economically most important broadleaved tree species in the Czech Republic, was strongly reduced in the past. Today there are efforts to...
Horizontal structure of forest stands largely affects the competitive relationships between tree individuals and plays a significant role in the stand dynamics. The present study describes horizontal ...
The investigation of the hydrothermal exposure effect on the glue-line strength is obvious when outdoor application of wood products is in option.
The paper deals with assessment of a long-term experiment (45 and/or 53 years of investigation) in the 90-years-old European beech (Fagus sylvatica L.) stand in a selected region of East Slovakia. T...
We developed optimal models for predicting the aboveground biomass of European beech (Fagus sylvatica L.) applicable to the national forest inventory data of the Czech Republic. The models were base...
The results of long-term monitoring of beech bark necrotic damage in a mature stands in Czech Republic, Slovakia, Poland, Hungary, Romania, Serbia and Bulgaria are presented in paper. Overall, 10,863 ...
The issues related to appropriate management methods of beech stands have been considered as a crucial topic from the past up to now. Although the positive effect of tending on wood quality in beech...
The onset and course of selected vegetative phenological phases of beech along the altitudinal gradient in Slovak Republic were studied. Observations were done in the Burda Mts. (200–300 m a.s.l.), Kr...
We evaluated the research on silviculture-production in the last 45 years in a 105-year-old beech stand, not tended up to its stand age of 60 years. Four alternatives (tending regime) were studied for...
We studied old beech trees individually dispersed in spruce monocultures after having found wildlings in their vicinity. The goal was to define stem and crown dimensions of the trees in dependence on ...
Recently individually dispersed adult beech trees have regenerated in spruce monocultures and this fact could be used to manage the transformation of stands into a mixed forest. Three such cases in th...
The article presents results of research focused on the development of natural regeneration of beech stands in the National Natural Reserve Voděradské bučiny, based on information acquired in reg...
The natural regeneration of beech (Fagus sylvatica L.) was studied under various shelterwood densities and silvicultural treatments in senescent beech stands in Central Bohemia. Four permanent researc...
The author analyzes the changes in the tree species composition of Dentario glandulosae-Fagetum Klika 1927 em. Mat. 1964 in the mountain stands of Bieszczady National Park in 1993?003. The analysis ta...
