The Variability of Spruce (Picea abies /L./ Karst.) Compression Strength with Present Reaction Wood

Popis výsledku v původním jazyce

The aim of the research was to find out the variability of spruce (Picea abies (L.) Karst.) wood compression strength limits in the direction parallel to the grain. The wood strength was examined using samples from a tree with present reaction (compression) wood. The strength was found out for individual stem zones (CW, OW, SWL and SWR). The zone with present compression wood (CW) demonstrated slightly higher values of wood strength limits. The differences of the limits of compression strength parallelto the grain in individual zones were not statistically significant. All the data acquired through measuring were used to create 3D models for each zone. The models describe the strength along the radius and along the stem height. The change of strengthalong the stem radius was highly statistically significant. There was an obvious tendency towards the increase of the strength limit in the first 40 years. With the increased stem height, there is a slight decrease of wood strength.
