STAGE GROWTH OF TREES AND ITS EFFECT ON SELECTED PROPERTIES OF NORWAY SPRUCE WOOD (PICEA ABIES (L.) KARST.)

Witold Pazdrowski, Stanisław Spława-Neyman

 

ABSTRACT



The study covers juvenile, transient and mature wood of Norway spruce. It was acknowledged that there is a close relation between stages of growth and wood properties. It appears that wood as of material, biological origin has diversified properties from the butt log to the crown. The weakest part of the log is the middle part composed of the juvenile wood. For the purpose of this study differentiation of growth stages was based on the wood density.

Key words: stage growth, juvenile wood, transient wood, mature wood, wood properties..
