Selected characteristics of macro and microstructure of pine wood with developed reaction tissue within a single tree

Fabisiak Ewa, Pazdrowski Witold, Nowaczyk Jolanta

Annals of Warsaw University of Life Sciences - SGGW. Forestry and Wood Technology

2012

No. 77

227-231

The paper presents results of measurements for annual ring widths in reaction, opposite and lateral wood formed in the same vegetation periods in pine (Pinus sylvestris L.). In the compared wood tissues tracheid lengths was also measured. The widest annual rings were found in the reaction wood zone. In that area of the stem cross-section tracheids were by approx. 20% shorter than those located on the opposite side of the pith.
