Množení okrasných dřevin dřevitými řízky s využitím černé fólie
Mejtská, Jana
ABSTRACT The aim of this work was to test the effect of propagation time (autumn or spring) on propagation effectivity of four woody species. Further, the use of growth stimulator and the use of black plastic cover for planting were tested during both autumn and spring terms. The experiment was performed on the experimental area of the Department of breeding and propagation of horticultural plants. The autumn part of the experiment was started on 11th November 2009, the spring part began on 15th March 2010. During both experimental terms, following woody species were cut and planted: Cornus alba, Deutzia gracilis Nikko, Deutzia scabra Plena a Ligustrum ovalifolium. Half of the cuttings were planted under the black plastic cover, half was planted without the use of the cover. In each half the use of stimulator was tested -- the cuttings were stimulated by IBA solution for twelve hours. All experiments were performed in triplicate repetition. The propagation effectivity was evaluated on the basis of the amount of rooted cuttings and the length of adventitious roots. The results show that during the spring term propagation was more effective than during autumn. The use of stimulator or plastic cover did not significantly effect rooting. Based on the experiment results I recommend spring propagation of the woody species which enables thorough rooting of the cuttings before winter. The best rooting was observed in Deutzia scabra and Ligustrum ovalifolium. These woody species should be propagated with the use of hard wood cuttings. Rooting of some tested species Deutzia gracilis and Cornus alba was insufficient regardless of experimental conditions. In these species, another way of propagation should be considered.

Schopnost kokrhele menšího (Rhinanthus minor L.) parazitovat na vybraných druzích trav a snížit produkci jejich nadzemní biomasy
Křeček, Tomáš
In past, yelow rattle (Rhinanthus minor) was considered as a weed in grasslands due to grass yields reduction and rapid loss of its forage quality. But today it is valued for its ability to reduce the competitiveness of aggressive species of grasses, allowing restoration of species-rich grasslands. In dry and warm conditions in southern Moravia there was tested the suitability of different grasses to serve as host of Rhinanthus minor. The impact of irrigation was also assessed in drought conditions during spring growth on the production of aboveground biomass hemiparasitic plants and their hosts. The last part of the experiment was a test hydrophobicity and infiltration capacity of soils. Field experiment was established in Žabčice experimental station of Mendel University in Brno. To determine the ability of Rhinanthus minor to parasite on various grasses red fescue, Kentucky bluegrass, perennial ryegrass and tall fescue were chosen. Irrigation significantly increased the number of plants and biomass of Rhinanthus. The largest nu-mber of plants and the highest biomass of Rhinanthus minor was found on irrigated plots with tall fescue. On the other hand, the smallest number of plants and the biomass were on the plots with red fescue. These differences are probably related to the ability of the host plant to cope with adverse environmental conditions. The experiment results in finding that red fescue is not a suitable host for Rhi-nanthus minor in dry and warm conditions in southern Moravia. On the contrary, it se-ems that the perfect hosts are deeply rooted tall fescue and clonal (rhizomatous) smooth stalked meadow grass.

Studium morfologických změn u révy vinné
Holub, Stanislav
This bachelor thesis deals with grapevine diseases typical especially for Neuburger and Aurelius cultivars but also observed in a whole range of other varieties. The disease is marked by a considerable retardation of the creeping growth of annual rings with the so-called "zig-zag" growth pattern and the consequence is a significantly lower yield of grapes and later often the death of the plant. Experiments established and carried out in Velké Pavlovice vineyards were focused on the elimination of this disease by means of application of gibberellin (gibberellic acid) to affected plants which resulted in removing the symptoms of the disease and restored the standard growth of annual rings. The use of extracts containing humin acids also yielded positive results. I would like to deal with this topic in my further studies.

Projekt lokálního územního systému ekologické stability v katastru obce Třebenice
Nedomová, Martina
The aim of this diploma thesis is to design a project of local territorial ecological stability system in the cadastral municipality Třebenice based on the framework of ecological stability. An important basis for the project development is my Bachelor thesis that deals with defining the framework of ecological stability. Part of the project is the draft measures for current elements of territorial system that are important to enhance their ecological stability. For the newly proposed compositional elements there are proposals of plantings elaborated as well as necessary after-care, estimated realization cost and the possibilities of obtaining state grant support. Implementation of this project would significantly increase representation of the green vegetation in the landscape of prevailing agrocenoses.

Economic Aspects of Wind Energy Production in the Czech Republic
Mešková, Alena ; Ryvolová, Ivana (advisor) ; Zemplinerová, Alena (referee)
Over the past few years in the Czech Republic has significantly increased the interest in electricity production from renewable sources, wind power plants are no exception. In connection with them, there are several technical and economical issues, some of them deals with this work. The first part focuses on the theoretical framework of the studied area. It includes a historical developments and legislation related to wind energy issues, and the matter of interest groups operating in this area. The second, analytical part deals with the evaluation of economic aspects of wind energy production. How is this resource economically effective as well as regulation of this industry itself is a sensitive issue for many years. Therefore this part focuses on the costs associated with energy production from VTE and their impact on prices for final consumers. Furthermore, there is the analysis of ROI to VTE by regulated and unregulated purchase price of wind energy and there are stated the changes on the market provoked by the existence of regulatory measures in this area.

Optimized biological method for the detection of sensitivity of red clover varieties to white clover mosaic virus (WClMV) and red clover mottle virus (RCMV) infection in the climatic conditions of the Czech Republic
Jakešová, H. ; Fránová, Jana
Red clover is a very important leguminous plant used in crop rotations on arable land, in temporary as well as permanent clover and grass stands. The persistence of clovers is negatively influenced by pests and diseases that attack the root and shoot parts of the plant. In the course of studies into the presence of viral diseases (2007–2011), the most frequently detected viruses were White clover mosaic virus, (WClMV, genus Potexvirus, family Alphaflexiviridae) and Red clover mottle virus (RCMV, genus Comovirus, family Secoviridae). The two viruses were observed in populations of clover throughout the Czech Republic. RCMV significantly reduced the yield and stand persistence of red clover. Given that no direct protection has yet been developed against the viruses, plant breeding directed to enhancing resistance to both WClMV and RCMV offers good prospects. Both viruses are mechanically transmissible.

The impact ofthe construction ofthe golf courseon the environment- the project EIA Český Krumlov
HÁVOVÁ, Nikol
The theme of this diploma thesis was effect building a golf course on the environment - EIA Czech Krumlov. On location Kvítkův Dvůr in Czech Krumlov was suggested build an 18-hole golf course. Construction of a golf course in this area may significantly distort the historical landscape. On the given locality conducted a biological exploration. Research has proved that there are no rare or endangered plant and animal species, therefore, the realization was possible. However Kvítkův Dvůr is an important cultural monument, which falls into the protection zone urban conservation.

Kameníková, Petra ; Šyc, Michal ; Krausová, A. ; Pohořelý, Michael ; Zach, Boleslav ; Svoboda, Karel ; Punčochář, Miroslav
This paper will present the composition of bottom ash determined in samples obtained from MSWI plant in Prague. The samples were first screened into fractions of grain sizes 0–2 mm, 2–4 mm, 4–6 mm, 6–8 mm, 8–10 mm, 10–15 mm, 15–20 mm and >20 mm. Each fraction, with the exception of fines bellow 2 mm, is manually sorted into glass, ceramics, magnetic particles, non-ferrous metals, unburned organics and the residual mineral fraction. It was found that the bottom ash contains in average 15–20 % of glass, 2–4 % of ceramics, 15–20 % of magnetic metals and around 2 % of non-ferrous metals. These results show that the bottom ash from in the Czech Republic is not significantly different from other European countries and has the potential for material recovery.

Využití ramopových pastí (ramp traps) pro průzkum biodiverzity - review
Skopalová, Barbora
The aim of this thessis is to review the method of collecting invertebrates using ramp traps with a focus on epigeon, ie invertebrates living and moving onthe earth's surface. Compare the advantages and disadvantages of this method with ground traps and suggest why using those traps or not. Both methods have their advantages and disadvantages, but the benefits greatly outweigh the ramp traps. In the case of ramp traps the material is always clean and free of impurities fallen plant material. It is hinted significantly less vertebrates and more needed invertebrates (ground beetles, spiders). They are difficult to prepare, but the actual use in the field is easier. They do not require distortion field diging as the method of ground traps. Based on the findings can be clearly recommended transition from ground traps to the ramp trap.
