In this thesis is evaluated the xylem structure of Norway spruce needles depending on solar radiation and altitude. Same-age spruce stand has been selected on the area of Hruby Jesenik at different altitudes on the southern and northern exposure. Sun needle samples were taken on each stand. The analysis of xylem structure was done. The number of tracheids, tracheid diameter, tracheid area and xylem area were evaluated. It was found that more than 50% dependence of xylem parameters on altitude and solar radiation, where exposure significantly affects the xylem structure only at altitudes above 1 200 m. The prediction maps show that the highest values of predicted xylem parameter values are found between 800 m and 1200 m about sea level.
