The first reaction of soil mite fauna (Acari, Mesostigmata) caused by conversion of Norway spruce stand in the Szklarska Por阞a Forest District
Mesostigmata mites forest conversion
2015/3/16
To observe the first reaction of Mesostigmata mites for conversion of even aged spruce stands under conversion with common beech and silver fir, four pairs of experimental plots directly neighbouring ...
Variability of spruce (Picea abies [L.] Karst.) compression strength with present reaction wood
strength parallel to grain spruce compression wood
2015/3/16
The aim of research was to find out the variability of spruce (Picea abies [L.]) Karst.) wood compression strength limits in the direction parallel to grain. The wood strength was examined using sampl...
Variability in density of spruce (Picea abies [L.] Karst.) wood with the presence of reaction wood
spruce density compression wood
2015/3/6
The study was aimed to assess the integral value that determines wood properties − wood density at a moisture content of 0% and 12%. The wood density was researched in a sample tree with the pre...
Growth reaction of young wild cherry (Prunus aviumL.) trees to pruning
pruning production height
2015/3/5
A large crown is one of the most important prerequisites for the good growth of a tree and therefore the crown could be called an engine of increment. The care for a large crown brings a decrease in t...
Reaction of Silver fir (Abies alba Mill.) plantation to fertilization
Silver fir site amelioration species composition reforestation apical dominance
2015/2/6
Silver fir as a domestic species is an important tree in our forests. Unfortunately it has suffered from serious dieback in Central Europe in the last decades. Reintroduction of Silver fir is not an e...
Effect of the position in a stem on the length of tracheids in spruce (Picea abies [L.] Karst.) with the occurrence of reaction wood
spruce tracheid length of tracheids compression wood
2015/2/6
The paper was aimed at the determination of variability of tracheid dimensions in spruce wood in relation to the position in a spruce stem. Significant changes in dimensions were found in early-wood a...
