This thesis is about analysis of morphometric parameters of Norway spruce tracheid wood from research areas Bílý Kříž and Rájec–Němčice. Wood for examining was sampled from different heights of trees. Width of the annual ring and percentage of late wood was determined at macroscopic level. Annual ring width ranged from 2,2 to 4,5 mm. The percentage of late wood was found to be 24 %. Microscopic analysis of tracheid wood dimensions followed. Radial size of tracheids was determined and averaged 31 μm. Tracheid cell wall thickness ranged from 2 to 10 μm. The number of tracheids increases with trunk height as does the width of the annual ring. Wood density of sampled wood averaged 450 kg·m-3. The variability of the wood structure by radius and height was examined. Subsequently, the obtained data was compared with precipitation and temperature. |
