Derivation of target structure for forests of Norway spruce vegetation zone in Slovakia
Norway spruce target structure naturalness vlase
2015/3/6
Forests of the Norway spruce altitudinal vegetation zone occur on the upper limit of tree vegetation and they fulfil important ecological and social functions. A great part of these forests are man-ma...
Derivation of target stocking for forests of Norway spruce vegetation zone in Slovakia
target stocking static stability slenderness coefficient
2015/3/6
The present paper deals with derivation of target stocking in forests of Norway spruce vegetation zone. Target stocking in forests with prevailing ecological and social functions is the stocking when ...
Allometric relationships for surface area and dry mass of young Norway spruce aboveground organs
allometry biomass Picea abies
2015/3/5
Tree-level allometric functions for a precise predicting of stem, branch and leaf mass and surface area of three needle-shoot age classes were estimated from measurements of crown and stem dimensions ...
Structural diversity change and regeneration processes of the Norway spruce natural forest in Babia hora NNR in relation to altitude
Norway spruce virgin forest
2015/3/3
The research was focused on exploring the dynamics and forms of regeneration processes and structural
diversity of the Norway spruce virgin forest in Babia hora NNR in relation to altitude. In each ...
Comparison of Norway spruce (Picea abies [L.] Karst.), Scots pine (Pinus sylvestris L.) and European larch (Larix decidua Mill.) stem shape by means of geometrical methods
Norway spruce Scots pine European larch stem shape
2015/3/3
In this article the stem shape is compared in three coniferous tree species: Norway spruce, Scots pine
and European larch. Stem is investigated by means of geometrical methods. Simplified Bookstein ...
Effect of Mg fertilization on yellowing disease of Norway spruce at higher elevations of the Šumava Mts., Czech Republic
Mg deficiency defoliation long-term effect
2015/3/3
Norway spruce yellowing and defoliation caused by Mg deficiency was frequently recorded on many sites
of the Šumava Mts. (Bohemian Forest Mts.) since 1980’s. A forest experiment aimed at invest...
Regional analysis of climate change impact on Norway spruce (Picea abies L. Karst.) growth in Slovak mountain forests
climate change impact tree ring radial increment
2015/3/3
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...
Development of Vaporization Process from Young Stands of Norway Spruce and European Beech after Snow Breakage
evapotranspiration soil evaporation young forest stand
2015/3/1
The extreme disturbance of the forest environment in the young experimental spruce stand in the Orlické
hory Mts after the snow breakage disaster in the winter of 2005/2006 became the impulse for th...
Production of Norway spruce (Picea abies [L.] Karst.) seedlings on substrate mixes using growth stimulants
Norway spruce seedlings substrates and their mixes biostimulant treatment
2015/2/6
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 ...
Effects of pressure on the root systems of Norway spruce plants (Picea abies[L.] Karst.)
root growth stress pressure RAI Picea abies(L.) Karst
2015/2/6
Roots are stressed quire often under natural conditions, e.g. when considering sloping terrain, layers of fluvial deposits, huge layers of melting snow, load of heavy forest machinery during logging a...
Possible methods of Norway spruce (Picea abies[L.] Karst.) stem shape description
Norway spruce (Picea abies [L.] Karst.) stem shape Bookstein coordinates stem shape diameters Procrustes tangent coordinates principal components analysis
2015/2/6
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...
Structure and functions of the types of Norway spruce (Picea abies[L.] Karst.) roots
