The thesis follows the bachelor thesis on comparison of morphological and economic parameters of various types of seedlings, which resulted in the planting of containerized and bare root seedlings of the European beech (Fagus sylvativa Linne) and the English oak (Quercus robur Linnaeus) in a forest regeneration in September 2011 and April 2012. The measurement of the height and thickness of the root neck of the seedlings was carried out on designated plots in March 2015. I also investigated possible mortality from the afforestation inspection in July 2012. Furthermore, 154 seedlings, 84 containerized seedlings a 70 bare root seedlings, in order to evalutate the development of the root system, its possible deformation and subsequently detection of the volume by using xylometric method. The data collected in the field were processed into tables and compared with the results observed in the bachelor thesis. The average figures for the height, the thickness of the root neck and the volume of the root system showed almost identical development of bare root and containerized seedlings in the forest cover, even though the figures of individual seedlings were highly variable. When reviewing the development of the root system, I found unacceptable deformation of the main taproot at 25% containerized seedlings and 20% bare root seedlings. The remaining seedlings were without deformation or with acceptable deformation of the taproot (wavy taproot, unbalanced taproot with the axis in the above-ground part, an outgrowth). It was discovered that containerized seedlings were more easily removable from the ground, the seedlings were not sufficiently fixed in the ground and its root system was in some cases less developed than it was with bare root seedlings. This may be influenced by several factors, e.g. the influence of richness of the root system on fine roots, the obstruction of development of the root system by cementing the surrounding soil when using the slit method. The bare root seedlings, the English oak in particular, showed root development to a greater depth, which is very important not only for sealing but also as an important factor in the drought season and extreme summer temperatures when there is rapid exhaustion of the moisture in the upper horizon of the soil due to the vapor. Unfortunately, it was not possible to verify these findings in a larger sample size, as there had been major damage of the forest.

The aim of this diploma thesis is to evaluate the growth of cultures and stands estabilished using bare-rooted and ball-rooted planting stock on working-plan area, forest district Jablunkov. For this purpose a total of 23 stands were selected (evaluated) on 46 research plots on forest district Jablunkov. In addition, the two economically most important tree species were selected for research; Norway spruce (Picea abies L.Karst) and European beech (Fagus sylvatica L.). These areas were selected on the basis of geographic and typological differences of habitat. A minimum of 60 viable individuals from bare-rooted and ball-roted group were measured on each plot and also the root deformations of the selected tree species were measured. The following parameters were measured for each individual: the height of the above-ground parts, the last accretion, the thickness of the root collar, the number of branches, the length of the branches, the size of the assimilation apparatus. The following features have also been observed and evaluated: loss, vitality, damage, trunk shape, crown shape, and root system deformations. From the results it was found out that out of 23 stands, ball-rooted planting stock was evaluated as better in 16 cases, in 5 cases was better bare-rooted planting stock and in 2 cases no better variant was found. In assessing of the root system, it was found that up to 100 % of the root system deformation was found in both types of planting stock.

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.

The purpose of this diploma thesis was to compare and evaluate the growth of potted and bare-root seedlings planted in locations SLT 5K, 2K, 2S and 1K, where trial areas were established. In 2014 200 potted and 200 bare-root seedlings of European spruce, European beech and Douglas fir were planted in these areas and only Scots pine was planted and evaluated in location SLT 1K. 10 parameters and 5 traits were measured and evaluated in all the areas and on all the planted plants at the end of the growing period of 2017. A statistical evaluation was subsequently performed according to individual location and seedling version. The results clearly indicate that the highest mortality was in areas located at SLT 1K and we can say that potted Scots pine grew best in this area. Potted European beech grew best in location 5K. Potted European spruce grew best in location 2K. The potted versions of the planted seedlings were not found to have grown better at location 2S according to the overall evaluation and no difference was found in the European beech or the Douglas fir in growth between the measured alternatives.

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.

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.
