Micropropagated plantlets derived from selected clones of the hybrid aspen (Populus tremula × Populus tremuloides) and the rowan-tree (Sorbus aucuparia L.) were used to determine the comparative study of uptake of the toxic, heavy metals Cd, Pb and the essential metal Mn. Samples of roots and aboveground parts (hypocotyl-derived tissues, leaves and stems) were taken from the plantlets grown for 24, 48, 96, or 168 hrs under aseptic conditions, in hydroponics with the toxic heavy metal and the essential metal salts. The concentration and distribution of the accumulated metals were determined using the ICP-OES method. The differences in...

Possibilities of using rooted cuttings of European beech (Fagus sylvatica L.) for stabilisation of forest ecosystems

Vegetative propagation of forest tree species is of great importance not only for breeding programmes but also for the conservation of valuable populations of tree species. Important is also a possibility of improving the genetic quality of established stands. Beech is a tree species that can substantially increase the stability of forest ecosystems. Minimal information is available about the ontogenesis of rooted cuttings of beech in forest stands for the time being. In our experiments that were gradually established since 1993 we acquired the first significant results of the evaluation of health status, phenological phenomena and growth of these...

Influence of a planting hole application of dolomitic limestone powder and basalt grit on the growth of Carpathian birch (Betula carpatica W. et K.) and soil chemistry in the air-polluted Jizerské hory Mts.

The objective of the study was to evaluate the growth potential of Carpathian birch (Betula carpatica W. et K.) at an environmentally harsh mountain site and a response of this species to altered soil chemistry after dolomitic limestone and basalt grit applications. The Carpathian birch proved to be a suitable species for the replanting of extreme acidic mountain sites. This birch shows a low mortality rate, grows well in the clear-felled patches and soon forms a cover which is necessary for the reintroducing of more sensitive tree species. The application of dolomitic limestone and basalt grit resulted in the slower growth of Carpathian birch...

Experiences with forest reclamation of settling basins after industrial processing of manganese ore and pyritic shales

P. Čermák, F. Fér

J. For. Sci., 2007, 53(11):516-522 | DOI: 10.17221/2025-JFS  

This article describes the problem of forest reclamation of settling basins after industrial processing of manganese ore and pyritic shale at the age of 20-30 years. Soil properties of anthropogenic soil (overlaid layers, deposited sediments), nutrition state of assimilation organs, vitality of aboveground organs of tree species were investigated by instant visual evaluation using recommended macromorphological criteria and architecture of the Scots pine (Pinus sylvestris L.) root system.

Influence of soil temperature and precipitation depth on the biomass production of fruiting bodies of macromycetes in a submountain beech forest stand

R. Janík, I. Mihál

J. For. Sci., 2007, 53(11):523-527 | DOI: 10.17221/2024-JFS  

The paper deals with research on the biomass production of fruiting bodies of macromycetes in a submountain beech stand in dependence on selected climatic variables. The study was carried out at the Ecological Experimental Site (EES) Kremnické vrchy (Central Slovakia) in 2003 and 2004. The biomass production of sporocarps on the EES plots in the two study years was different (5.81 kg/ha of fresh biomass of sporocarps in 2003 and 39.95 kg/ha in 2004) due to better ecological and climatic conditions and higher abundance of sporocarps in 2004. It is necessary to mention that these values reflect the overall status of mycocoenoses on the plot. Unfavourable...
