Možnosti výsadby prostokořenného sadebního materiálu v zimním období
Vacková, Jana
The goal of this thesis is to elaborate the possibilities of winter time planting of bare rooted planting material. Because of this were there planted two bathces of plants on the planting area. One in winter time, the other in spring. With both the planting batches there was used the same planting material. There were planted two wood plants – spruce and beech, both in bare rooted and root covered variante. During the groth there happend two measurings. The control one in June, the final one at the end of the vegetation period. The final measuring was made on 100 subjects from each variante. The lower amount was tested only by the root covered spruece due to high losses. By each subject there were mesured these conditions: the height ot hte above ground plant parts in the time of planting and the difference at the time of last measuring, the diametr of the root collar, the lenght and width of the assimilation aparatus. There were also evidated conditions like the color tone of leves, the type of damage, multiplicity of the trunk and losses. Results showed that it is much better to do the planting of bare rooted spruece in spring time. The bare rooted beech is different case – here is absolutely better the winter planting time option. It shows better results. In addition it was shown that the root covered planting materiál is not optimal for spring planting time.

Využití krytokořenného a prostokořenného sadebního materiálu v nastávajících klimatických změnách
Mergl, Václav
The aim of this thesis is to evaluate the use of containerized and bare-rooted planting stock in the upcoming climate change. Four research areas at different sites in SLT 2S, 6K, 6S and 7K (Czech forest ecosystem classification) and in different climatic areas were chosen for this purpose. Furthermore three timber species for the research were selected, namely European beech (Fagus sylvatica L.), Norway spruce (Picea abies (L.) Karsten) and Douglas fir (Pseudotsuga menziesii (Mirbat.) Franco). 300 dormant individuals of the containerized and bare-rooted version of the chosen wood species were planted on each research area. 100 individuals of each variant in all species were measured after the growing season. Following parameters were measured on each plant: height of above-ground part of the plant, height of above-ground part of the plant at the time of the planting, shoot lenght, root collar diameter, crown width, length of the assimilatory organ, width of the assimilatory organ, trunk straightness, axis deflection of the trunk from the vertical axis. If trunk multiplicity occurred, the height of the trunk deployment was measured. Atributes such as color of the assimilatory organ, crown shape, type of loss or damage of the plant and the multiplicity of vertex were also observed. As a result it was found that it is necessary to maintain the natural tree species composition. Also it was revealed that the bare-rooted planting stock has a better survival rate on drier stands, precisely on SLT 2S. The SLT 6S, 6K and 7K were found to have better survival rate of the containerized planting stock. This finding indeed cannot be aplied at sites in SLT 6S and 7K where the beech had the same grow out rate.

Růst a vitalita prostokořenného a krytokořenného sadebního materiálu při obnově stanovišť středních a vyšších poloh
Mácha, Michal
The aim of the thesis was to compare the growth of containerized and bare-rooted planting stock. For this purpose suitable location on set of forest types 5K, 5S, 6K, 6S, 7S and 7K were selected where sample plots were based. On each of these areas 200 pieces containerized and 200 pieces bare-rooted plants of European beech, Douglas fir and Norway spruce were planted. At the end of the growing season the height and diameter of root collar were measured with 100 plants of each variation, further the vitality and mortality were found out. At the same time the further parameters were investigated which led to clarifying the results. Subsequently the statistic evaluation was made according to the individual habitats and variants. The results show that the highest mortality was on areas located on sets of forest types 5K and 5S. It was also found out that a small height of the above-ground part of containerized planting stock of Douglas fir influences negatively the growing up just after planting. With European beech and Norway spruce no significant differences were found between containerized and bare-rooted planting stock.
