Vliv nadmořské výšky a jižní expozice na morfologicko-anatomickou stavbu jehlic smrku ztepilého

In the introduction of the thesis is a literature review focused on the morphology, ecology, area of occurrence and the influence of climate on the growth of Norway spruce. Three same-age spruce stands were selected in Jeseníky mountains which had different altitude and the same exposition. Samples of one-year old sun-exposed shoots were taken from the selected stands. On the needles was carried out the morphological-anatomical analysis. It was found, that altitude affects the needle parameters - needles at higher altitudes compared to needles growing on spruces at lower altitudes are thicker, wider, shorter and relatively the area of central cylinder increase compare to needle cross-section area. Exposure affects only the cross-section area, length and the projected area of needles. Using geospatial technologies have been developed predictive maps of solar radiation and altitude influence on needle parameters
