Adaptation variability and ecological plasticity in the “genotype-environment” system of 22 provenances of Picea abies (Linnaeus) H. Karsten, Picea obovata (von Ledebour) and their introgressive hybr...
Our research was concerned with a description of the influence of variability in average temperatures on the height growth of selected young populations of spruce in the Krkonoše Mts. Several pop...
As the tree age increases, the formation of heartwood takes place in the central part of the tree. Since there is a large difference in the moisture content between sapwood and heartwood in conifers, ...
This paper presents findings of a twenty-year investigation of silviculture-production in a 40-year-old afforested spruce pole-stage stand located in a mountain region. The stand was established by fo...
The main objective of this study was to investigate the causes of nutrient deficiency symptoms in Norway spruce (Picea abies [L.] Karst.) underplantings in the Hruby Jeseník Mts. In the area concerned...
Laboratory-produced alginate-bead inoculum of ectomycorrhizal (ECM) fungi Cortinarius sp. and Gomphidius glutinosus, fungal commercial products ECtovit® and Trichomil®, bacterial commercial ...
Effects of drought, Al and their possible interaction on physiological characteristics were studied in four-years-old Norway spruce seedlings in a pot experiment. Drought stress was imposed by withhol...
Natural mixed beech-fir forests were quite widely replaced by spruce dominated stands in Slovakia. Given the demands on the assessment of the forest status as well as on stopping the biodiversity loss...
In the years 1987–1993 research aimed at the qualitative and quantitative composition of insects inhabiting the cones of Norway spruce (Picea abies [L.] Karst.) was carried out in the area of the Tatr...
Mineral nutrition represents the uptake, transport, metabolism and utilization of nutrients by the forest stand. These processes influence all physiological functions of trees. A specific minimum amou...
High quality of planting material is an essential prerequisite for successful artificial forest regeneration. We carried out a detailed investigation aimed at differences between plantable bareroot an...
Interspecific comparisons of the fine root 揵ehaviour?under stressful situations may answer questions related to resistance to changing environmental conditions in the particular tree species. Our stud...
In the locality Hnilé Blatá (the High Tatras Mts.), the structure was measured of root branches in the windthrown spruces (Picea abies [L.] Karst.). After cleaning the root plates, the number, diamete...
The Bohemian-Moravian Upland shows a large-scale decline and dieback of Norway spruce up to the forest altitudinal vegetation zone (FAVZ) 5. This phenomenon has been observed in the last 7 years and i...
The soil is an irreplaceable component of forest ecosystems. Soil-forming processes directly influence element cycling (EC). Plant-soil interaction is a specific part of EC. Plant-soil interactions we...
