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 ...
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...
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...
