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.

This diploma thesis primarily focuses on thermal modification of wood with superheated steam and its effect on elasticity and strength. The sample tested was 200 pcs of bending samples and 200 pcs compressive samples of European beech. These samples were divided into ten groups. One group was referential and the remaining nine groups were modified using different temperatures and during different time intervals. The main goal was to determine density, modulus of elasticity and rupture and to discover their dependence on the chosen mode of modification. The next part contains the analysis of the effect of thermal modification with superheated steam on the acoustic properties and the colour of wood. In the last part, the mass loss and the change in equilibrium moisture content was analysed in relation to the modification mode.

This diploma thesis deals with the issue of appropriate surface treatment for wooden floors in public interiors. The materials used in this thesis are coniferous (spruce) and foliate (beech and oak) types of wood which has been treated with four different kinds of transparent coating. The evaluation of the most appropriate coating for a particular kind of wood is based on laboratory experiments focused on physical-mechanical, chemical and microbiological properties.

The aim of this work was to find out how different planting biotechnique of the seed and different site have an impact on growth of container-grown planting material. It was planted norway spruce, european beech and sessile oak on SLT (czech typology system) 5K and 5G. Spruce and beech was planted with five different types of seedlings and oak with three different types. The influence of root ball overlap during planting was also investigated. Measurements took place in 2016, 2017 and 2018. In particular, the following parameters were investigated: the length of the aerial part, the increment, the thickness of the root neck, the length and width of the assimilation organs, the vitality, number of roots rooted in the root ball and the losses. The results show that, the growth of the container-grown planting material is influenced by different biotechnology of seedlings and sites. Planted plants grew better at 5K than at 5G. Best for norway spruce was planting cutter biotechnique for both sites. Best for european beech was center hole planting biotechnique, eventually planting thorn biotechnique. Best for sessisle oak was center hole planting biotechnique. The root pack is better to overlap with a layer of soil during planting.

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 thesis occupies with environmetal limits and the european beech and oak trees in natural forest area 17–Polabí. Forests, whose age was at least 100 years, were mostly selected for the evalution. Signs of tree growth of both species has been reported in forest stands. It was also evaluated the quality and even the shape of the crown and the quality of the trunk. Last but not least, the incidence of harmful agents has been assessed. Data collection took place in the summer of 2018. In consequence, it was found that there are not ecological limits of both species in this area. At the same time it was it was found that there is no statistically significant difference between first vegetation tiers and second vegetation tiers. The both species growth is very similar, if not the same. Moreover, as expected, the difference between the 2nd and 3rd vegetation tiers in both the total height and the deployment height was proved. At the same time there has been no cause significant damage. Only Lymatria dispar has been detected relatively abundant occurrence.

The aim of this Master thesis was to assess the survival and growing out of container planting stock for the Norway spruce (Picea abies (L.) Karst) and the European beech (Fagus sylvatica L.) after the set period of stressing by dessication due to incorrect manipulation. The plants exposed to desiccation for 2, 3, 4 and 5 days were planted in a research area. During the first day of testing, the variant for checking of unstressed planting stock was planted. The research also included the testing of new methods for assessing root ball water loss during plant desiccation. The method for measuring the decrease in weight of a root ball during manipulation was used and two devices for measure moisture levels in root balls were tested (HH2 and WHT 860). The first assessment was carried out five weeks after planting out, during which vitality and sprouting progress were assessed. The second assessment took place at the end of the vegetation period, and vitality, duration of apical increment, thickness of the rootcollar and the length of needles and leaves were assessed. It was confirmed that with an increased duration of root ball desiccation comes the loss of moisture which after a certain period of time negatively impacted the survival and growing out of the tested plants. The limit for the root ball was a 3-day-long exposure of the planting stock to desiccation. The spruce planting stock is significantly more resistant to the negative effects of radiation and desiccation than the beech planting stock. The minimal threshold for moisture levels was set, determining when the planting stock can grow out without any major problems. The tested methods appear to be promising and can be used to assess the planting stock quality before the planting.

The aim of this work is to analyze data on the damage caused by game from the database Field-Map program of operational statistical inventory. This inventory was carried out in 280 inventory plots to forestry section Borky school forest enterprise Masaryk forest Křtiny, in 2003, 2008 and 2013. Another aim is a suggest a method and a method of long-term monitoring of game damage to forests. Information on damage by game were evaluate in the relevant graphs in relation to the type of stand (coniferous, broadleaf and mixture) edaphic categories and game evidence (above game hunting). Next, the data were compared based on the general linear models in statistics. At principal species and accessory species in relation to the growth was the considerable increase by game damage. Data of game damage depending on edaphic categories showed the greatest harm to the ecological variety of nutrients. After the use of SPI in this work (the evaluation) and keep to relenvat principle of this system, this method was recommend as flexible method for long-term monitoring of the development of game damage to LÚ Borky.

This work deals with drying of the beechwood using microwaves. In the first part there is teoretically discussed the wood in general and its behavior related with drying. The beechwood is here described in detail and also its properties. Another point of the teoretical part is focused on microwaves and its use for drying wood. Second part deals with drying of the beechwood samples using continous microwave line. Twenty beechwood samples were split on radial and tangent samples and they were put on ma-chine belt of the drying machine. Before and after each entry through the drying machi-ne each sample was weighed. This process was repeated till almost zero moisture of the tested sample. Then small parts were cut from each sample, three from each edge and three from the middle part of the tested sample. Three parts (edge, middle, edge) were used for prong test, three for finding the value of crustiness using the CEN test and three of them cut on even smaller parts for finding the moisture gradient. The result was evaluation of wood drying and its quality after drying

Forest ecosystems plays an important role in the global carbon cycle of carbon sinks of terrestrial ecosystem. Carbon sequestered or stored in forest trees is mostly referred to as the biomass of tree, site or forest. This diploma thesis deals with biomass estimation of European beech stands at the Holíkov (the Drahanská vrchovina Highlands) and Štítná nad Vláří (the Bílé Karpaty Mts.) study sites in the Czech Republic. Study was conducted in the period of 2010 to 2015. 65 allometric equations were tested for the purpose of determining the most suitable candidate for the estimation of aboveground and belowground biomass of stands and of all the major tree compartments. It is obvious from the results that the allometric equations performed very differently from each other. It was also found, based on the obtained results, that the most suitable allometric equations for the study sites are by Vejpustková et al. 2013 and Wutzler et al. 2008.
