Možnosti a limity uplatnění prostokořenného a krytokořenného sadebního materiálu při obnově vybraných stanovišť středních a nižších lesních vegetačních stupňů

The aim of the bachelor thesis is a complex evaluation and comparison of the use of bare-root and container-grown planting material, with respect to planting and growth, so that the forest restoration would be more sucessful and effective. For this survey we set specific areas with suitable conditions related to habitat and altitude. The areas were located in particular forest types sets, specifically 4K, 4S, 3K, 3S, 3M. In each area we planted 200 bare-root and container-grown plants of European spruce (Picea abies L. Karst.), Douglas-fir (Pseudotsuga menziesii Mirb.) and European beech (Fagus sylvatica L.). The first finding in the following year after the forestation was a mortality. After the end of the vegetation period we evaluated 100 plants of each type and variety. The main measuring features included: the thickness of root neck, the height of above ground part, the mortality, the length of growth and other features that helped for the most accurate and objective comparison. Each variety and type of plants were measured, the data were evaluated and statistically compared
