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...
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...
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...
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...
The paper presents the results of a regional analysis of climate change impacts on Norway spruce growth in the north-western part of Slovakia (Orava region). Radial increment was determined from nin...
We evaluated the growth of Norway spruce (Picea abies [L.] Karst.) seedlings on peat and bark substrates, on their mixes and on their mixes with agroperlite. We examined the basic quantitative traits ...
The paper shows a possibility of using Bookstein coordinates for stem shape studies. Bookstein coordinates are simplified to stem shape diameters, for which tests of multidimensional normality, varian...
The aim of the study was to describe variability of the structure of roots in Norway spruce (Picea abies [L.] Karst.) from their growth tips to the stem foot, i.e. anchor roots in relation to their ch...
This study aims to investigate the changes in isotope ratios in foliage and soils of two Norway spruce (Picea abies [L.] Karst.) forests greatly differing in their atmospheric N deposition and climati...
