The article presents the results of inoculation of beech and oak stumps with a biological preparation of oyster fungus (Pleurotus ostreatus) mycelium. The inoculum was grown on a sawdust substrate at Warsaw University of Life Sciences Department of Mycology and Forest Phytopathology. The experiment was set up at the Forest Experimental Station in Rogów. Stumps were inoculated: i) immediately after...
The study presents the results of investigation on reaction of beech (Fagus sylvatica L.) leaves observed next year after planting seedlings in different positions in a young spruce stand located in upper mountain conditions. The methods of chemical analyses and assessments of chlorophyll fluorescence were applied with the aim to evaluate a course of leaf adaptation. In the young spruce stand located...
Support of European beech (Fagus sylvatica L.) and sycamore maple (Acer pseudoplatanus L.) plantations by amelioration has been tested in air-polluted sites in the mountains since 1993. The research locality is a site with humic podzol soils at an altitude of 960 m a.s.l. Dolomitic limestone (1 kg per tree) was mixed with soil used for planting tree seedlings. According to the results of a 15-year...
The research issue focuses on potential interception, which is the maximum amount of water that can be stored on plant surface. Tests under controlled conditions remain the best way to enhance knowledge on interception determinants in forest communities. Such tests can provide data for identification of mathematical models based on ecological criteria. The study presented in this paper concerned tree...
Height-diameter models define the general relationship between the tree height and diameter at each growth stage of the forest stand. This paper presents generalized height-diameter models for mixed-species forest stands consisting of Norway spruce (Picea abies Karst.), Silver fir (Abies alba L.), and European beech (Fagus sylvatica L.) from Slovakia. The models were derived using two growth functions...
