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

Vaníček, Lukáš
The aim of the thesis is to find out the impact of the forest stand and the quality of the planting on the growth of Quercus Robur L cultures. For this purpose there was found 10 research forest plots at forest habitat types 3K, 4K, 3S, 3C, 3L, 3P situated in LS LČR Jeseník area. In 2014, a bare-root variant of Quercus Robur L seedlings was planted in each research plots using slot planting. In each research area, several parameters and traits of the above-ground part were detected in 100 individuals, and the root system was dug and analyzed in six individuals on each research area. After the end of the vegetation period in 2018, the above-ground part was measured, the following parameters and features were examined: height of the above ground part, height increment, lateral increment, root neck thickness, trunk ripple, trunk deviation the size and color of the assimilation apparatus, the damage of the cultures by biotic and abiotic factors. Root systems have been evaluated for root depth, main root length, incidence of stumbling, absence of stakes or panohs, and p-index value. The results clarify that culture at nutrient and water-enriched habitats have better vitality. The worst results were found by 4K forest type.

Porovnání růstu prostokořenného a krytokořenného sadebního materiálu
Souchová, Jana
The aim of the thesis was to compare and evaluate the growth of bare-rooted and rooted seedlings of the same tree species based on the findings. All trees compared and monitored in this work were planted in the same area of the cane, in 2016. The evaluation was carried out on 4 research areas, these areas are characterized by sets of forest types 2S (fresh beech oak), 6K (sour spruce beech), 6S (fresh spruce beech) and 7K (acid beech spruce). There are three species of woody species in these areas, namely Norway spruce (Picea abies (L.) Karst.), Douglas fir (Pseudotsuga menziesii (Mirb) Franco) and European beech (Fagus silvatica L.). On each plot, 100 individuals were subjected to measurement for each variant of planting material in the autumn of 2017, for which the following parameters were evaluated: losses, height of the overground part in 2016 (which was measured after the scar marking the last increment), height of the above ground part in 2017, increment in 2017, the length of branch growth in 2017, the width of the crown, the thickness of the root neck, the trunk deflection from the vertical axis, the length and width of the assimilation apparatus, the straightness of the stem, the vitality of the plant. Based on the results, the following conclusions were drawn: On the SLT 6K surface in the case of woody beech, the variant of planting material grew better. In contrast, barkless planting stock grew better in Douglas fir tree species. The Norway spruce tree then grew better in the rooted variant. In the overall assessment of the abovementioned factors, it can be stated that on the SLT 6K the rooted seedlings grow better. In the SLT 6S area, the species of beech was found to be better growing in the bare-root variant. The Douglas fir also grew better in the bare-rooted variant and Norway spruce was best grown in the rooted roots variant. The result is that the bare-rooted planting material grows better on SLT 6S. On the area of SLT 7K there was a better growth of the beech in the rooted variant, as well as the better overall results of the spruce in the openrooted variant. Douglas fir grew better on the area in the barefoot variant. To summarize the findings of the observation on SLT 7K, it can be stated that the better results are achieved and hence the growing of the rooted planting material. In the SLT 2S area, the results for the growth of beech wood were better in the bare-rooted variant; Douglas fir tree has not been evaluated for this area due to insufficient seedlings when setting up the research area.

This work is about comparison of bare-rooted and containerized planting stocks on 5 locations with different conditions, which were established for the purpose of this kind of research. Locations consisted of these forest type sets: 4K, 4S, 5K and two areas with a forest type set 3K. There were 200 bare-rooted varieties and 200 containerized varieties of three species planted on these locations in 2016, namely European beech (Fagus sylvatica L.), Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) and Norway spruce (Picea abies (L.) Karsten). After the end of the vegetation period in 2017, measurements were made on the mentioned trees. Hundred individual trees from each variant were measured. The following parameters and features were measured: height of the aboveground part in 2017, height of the aboveground part in 2016, length of the growth of branches, thickness of the root neck, width of the crown, length and width of the assimilation apparatus, ripple of the trunk, diversion of the trunk, height of split of multiple trunk, colour of the assimilation apparatus, crown shape, multiple top, losses. The measurements were further statistically evaluated and the results showed that the containerized variant of European beech has better growth at all evaluated locations. Containerized variant of all plants was better on 5K area than on the other areas. Bare-rooted variant of Norway spruce had better growth on forest type sets such as 3K,3K B,4K, and 4S. Bare-rooted variant of Douglas fir had better results on 3K (Svárov) and 4K areas, but containerized variant had better results on 3K (Vanovice) and 4K area.

Vliv biotechniky sadby krytokořenného sadebního materiálu smrku ztepilého a buku lesního na odrůstání kultur a vývin jejich kořenového systému v 7. lesním vegetačním stupni
Koudelík, Lukáš
The aim of the diploma thesis was to verify the influence of different seed plant biotechnics on the growth of cultures and development of the root system of the cryopreservation material of spruce and beech forest in the 7th forest vegetation stage. The monitoring was carried out at LS LČR Janovice on forest types 7P and 7K. As the main biotechnology for testing, the seedbed was planted, the seedbed was planted without and with overlay, the seedling was planted without overlapping and seeded with seedless forks without overlapping. The effect of the balloon overlay was also evaluated. To evaluate the influence of different plant biotechnology on the growth of the cultures and the development of the root system we mainly served the criteria of the height of the above-ground part, the thickness of the root neck, the size of the assimilation apparatus, the loss, the vitality, the development of the root system, etc. The best plant biotechnology was evaluated for the spruce spruce on the area 7P planting seedless pipe without overlap and on 7K area planted with seamless sowing. In the case of forest beech, 7P was evaluated as the best seedling without overlap and 7K seedbed without overlapping. The suitability of hole seedlings for both studied species and areas was confirmed. The effect of seedling on the deformation of the root system was confirmed.

Kohout, Karel
The aim of bachelor thesis was to find out the positives and negatives of the use of containerized planting stock on different sites. For this evaluation, operational plantings were estabilished, that were planted with containerized planting stock. On the same sites, planting with the bare-rooted planting stock were evaluated. The following woody species were compared: Norway spruce (Picea abies (L.) Karsten), European beech (Fagus sylvatica L.), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), silver fir (Abies alba Mill.), Scots pine (Pinus sylvestris L.), and European larch (Larix decidua Mill.). Each pair of plantings (with containerized and bare-rooted plants) has the same age and i tis on the same set of forest types (1K, 3B, 3S, 4B, 4S, 5K, 6S, 7K and 7P). It is evident from the achieved results that in 75% of the achieved results was better containerized planting stock.

Fojtík, Roman
The work was made in order to find out what influence it has on the growth of bare-rooted and cover-rooted material in habitats with a different set of forest types. The habitats were selected on forest type sets 3B, 3S, 4B, 5K and 5S. One research area was established at these sites, where the trees were researched for research: Norway spruce (Picea abies (L.) Karsten), European beech (Fagus sylvatica L.) and Douglas fir (Pseudotsuga menziesii (Mirb.) Franco). For this purpose, 200 individuals of bare-root varieties and 200 individuals of rooted varieties for each tree species were planted. When the growing season ended, data collection began in the field. Data collection was performed on 100 individuals from each variant. For the following comparison, the following parameters and features were ascertained: height of the aerial part, terminal flange, length of branch growth, root neck thickness, crown width, length of the assimilation apparatus, width of the assimilation apparatus, deflection of the stem axis, height of multiple stem deployment, color of the assimilation apparatus, ripple trunk, multiple trunk, crown shape, multiple peak, loss. Furthermore, the data were statistically evaluated and compared. This means that it could have an effect on the outgrowth of barefoot Douglas. This also applies to the rooted beech, except SLT 3S. The habitats with SLT 3B, 3S and 4B were better suited for the growth of bark-spruce, and on the site with SLT 5K and 5S there was a better influence on the growth of spruce.

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.

Hudzieczek, Jaroslav
The aim of the diploma thesis was to find out the state and the evaluation of the growth of cultures and stands based on plowed and cryopreserved seedlings on LS Náměšť nad Oslavou. The results show the current state of cultures and stands at selected habitats. The results should contribute to improving the quality and success of the artificial restoration of the forest. For the research and the final evaluation, research areas were selected, which in each pair had the same year of founding (differing by half a year of spring / autumn planting), were found on the same set of forest types. Comparison of research areas differed with the type of planting material used (cryopreserved, flattened). The research areas were on these forest types: 4S (5x), 4K (4x), 4O (2x), 3S (4x), 3H (2x), 3K (2x), 2K (1x). On each research area the parameters were measured on 60 specimens of the tree. The main measured parameters included above ground height, growth, root neck thickness, length and width of the assimilation apparatus, and other parameters needed to refine and to compare objectively. The measured values were evaluated using the statistical method and were compared for each variant of planting material and wood species. The results showed that there is a difference in the growth and development of the cultures and stands based on the cryopreserved and trimmed planting material, in favor of the cryopreservation planting material.
