Vliv nadmořské výšky a severní expozice na morfologickou a anatomickou stavbu jehlic smrku ztepilého
 Ambrož, Petr
There were chosen three localities even-aged spruce growth from different altitudes and northern exposure at the Jeseníky Mountains. Subsequently, literary review was composed. The introductory part to the bachelor's thesis is mainly focused on the description, ecology and the influence of climatic conditions on growth and assimilation apparatus of Norway spruce in. Later, sun-exposed one-year old shoots were sampled from the selected localities. Needles were taken from the shoots and then used for making the cross-sections. Other needles were taken for needle area and length analysis. Morphological and anatomical analysis was done on the microscopic pictures. Results were processed statistically by program Statistica 12. It was found that with increasing altitude the length and the projection area of needles are decreasing. The predictive maps for some morphological and anatomical parameters were also created by the use of elevations and solar radiation data in ArcGIS.
