Charvát, Zdeněk
The aim of the thesis was to compare the vitality of the containerized and bare-root planting stock in the changing climatic conditions of the environment. For this purpose, four research plots were set up at forest habitat types 6S, 6K, 7S, and 7K. On each of the research plots, the following tree species were planted evenly: Norway spruce (Picea abies (L.) Karst.), European beech (Fagus sylvatica L.) and Douglas fir (Pseudotsuga menziesii (Mirb.) Franco); each of the above-mentioned trees was planted in two variants – containerized and bare-root, 200 seedlings per each variety. Subsequently, after the end of the vegetation period, measurements were made on 100 individuals from each variant. The following parameters and features were compared during the measurements: height of the above-ground part, length of the terminal growth, length of the lateral growth, diameter of the root collar, straightness of the stem, deviation of the stem from the vertical axis, crown width, crown shape, length, width and colour of the assimilation apparatus, presence of the multiplicity of the stem, kind of damage. Results of the study show that the bare-root planting stock has a higher vitality than the containerized one at all the studied forest habitat types. The smallest differences were found in Norway spruce variants and the largest differences were found in Douglas fir variants.
