Eff ects of the position in a stem on the variability of tracheids in spruce (Picea abies /L./ Karst.) with the occurrence of reaction wood

Popis výsledku v původním jazyce

The paper is aimed at the fi eld of the microscopic structure of wood dealing with the description of the most important anatomic element in softwood -- tracheids in a stem with the occurrence of reaction wood. Signifi cant changes of tracheids were found along the height and radius of a stem. There were statistically signifi cant diff erences between particular annual rings (variability along the stem radius). The height of a stem was also statistically signifi cant. On the basis of the results obtained 3D models were created (for zones compression wood, opposite wood and site wood; models for radial dimension an early-wood tracheid and late-wood tracheid) depicting changes in transverse dimensions of the spruce tracheid in relation to its position ina stem. Structure of ring with compression wood was studied too. It was observed that the ring with occurrence of compression wood has a following structure: early wood tracheids at the beginning of the growing season, transitional trach
