Multivariate analysis for assessment of the tree populations based on dendrometric data with an example of similarity among Norway spruce subpopulations
dendrometry hierarchical classification ordination Picea abies
2018/3/6
The new method for evaluation of tree populations presented here is based on a correlation analysis within a set of
dendrometric variables. The correlation analysis is carried out for each population...
Effects of fertilisation on growth and nutrition of Norway spruce on a harsh mountain site
fertilization nutritional status Picea abies survival
2015/4/24
We evaluated the potential of crushed amphibolite and artificial slow-release N-P-K-Mg fertiliser to stimulate the survival, growth and nutrition of Norway spruce planted on an acidified air-polluted ...

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...
Can 13C stable isotope record of Norway spruce tree rings display the effect of environmental conditions?
Δ13C air pollution tree physiology Bohemian Forest Mts. soil pH aluminium soil acidification
2015/3/12
The Bohemian Forest Mts. (Šumava) were exposed to heavy atmospheric pollution in the last century. A possible negative effect of atmospheric pollution on tree physiology has been studied using th...

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...
Gradients of the content of photosynthetic pigments and radiation as manifestations of the health condition of Norway spruce (Picea abies [L.] Karst.)
chlorophyll carotenoids radiation transmittance health condition Picea abies (L.) Karst.
2015/2/2
The paper deals with the health condition of sample trees of Norway spruce (Picea abies [L.] Karst.) on the basis of the distribution and quantity of chlorophyll a + b and carotenoids with respect to ...
