The Diploma thesis is focused on the formation of commodity chain rapeseed on the common EU market. It reports the development of the supply side of rapeseed, rapeseed oil and biofuels on the world and european market. It identifies the main world and european production centers within those commodities. The development of prices in selected stages of commodity chain is analyzed by using the agricultural producer prices and stock prices. The analyses are based on the evaluation of statistical data. The results confirmed the growing significance of rapeseed and growing presence of biofuels.

This diploma thesis defines the evolution and changes of canola commodity chain in Czech Republic focusing on primary production and processing stage. Through literature review, based on the theoretical and methodological foundations of agribusiness, canola commodity chain, its determinants, and biological charac-teristics of the commodity are defined. Through analysis of secondary data is captured supply formation and evolution of oilseed rape production in the Czech Republic. Also there are identified changes in the structure of agricultural holdings in given commodity vertical.

The aim of this thesis was to evaluate weed infestation of chosen crops, to compare weed infestation among each crop and evaluate used regulation interventions, eventually to suggest another solution. Evaluation was made in winter oilseed rape, winter wheat and in spring barley. In the winter oilseed rape were found Viola arvensis, Triticum aestivum, Thlaspi arvense, Chenopodium album, Geranium pusillum, Fallopia convolvulus, Stellaria media, Lamium purpureum, Capsella bursa-pastoris, Veronica persica, Tripleurospermum inodorum and Cirsium arvense. In winter wheat were Viola arvensis, Veronica persica, Brassica napus ssp. napus, Lamium purpurem, Galium aparine, Geranium pusillum, Capsella bursa-pastoris, Thlaspi arvense, Chenopodium album, Stellaria media, Matricaria recutita and Cirsium arvense. In spring barley were Viola arvensis, Raphanus raphanistrum, Lamium purpureum, Veronica persica, Thlaspi arvense, Fallopia convolvulus, Polygonum aviculare, Galeopsis tetrahit, Chenopodium album, Galium aparine, Geranium pusillum, and Matricaria recutita. Weed infestation was processed by canonical correspondent analysis (CCA). Finally it was suggested to use different methods for weed regulation.

This thesis deals with the characterization and description of the commodity chain of rape oilseeds. It defines the development of production and production areas in the European Union and worldwide. Part of the work is devoted to the development of the commodity chain of oilseed rape in conditions of Czech republic. It describes and compares the review of the utilization of rape oilseed in our country. It analyzes foreign trade with this commodity and evaluates the long term developments in the process of EU enlargement. The work characterizes the price trends of oilseed rape and its potential impact on the price of petroleum. Using the data obtained, there are evaluated possibilities of rape oilseed in the future. The obtained results show that the Czech Republic is among the most intense growers and producers of rapeseed in the EU 28 and in the world.

The palm oil is the most desirable raw material in a wide range of industry in the 21st century. It is a basic material for food, cosmetics, biodiesel and many other products. However, it’s production has a negative impact on the environment. In this thesis the palm oil authenticity is judged according to the differences in composition depending on the conditions of cultivation, which is related to the certification of this raw material. The fatty acid spectrum in the samples of palm oil was determined by method of gas chromatography coupled with flame ionization detection. In terms of total fatty acids content, the non-certified palm oil (fat sample 1) containing 0.969 g.g-1 fat (after three months storage 0.880 g.g-1 fat) is better than certified palm oil (fat sample 2) containing 0.648 g.g-1 fat (after three months storage 0.533 g.g-1 fat).

Lot of attention is paid to biological control agents of plant pathogens as it will reduce the amount of pesticides used in agriculture. Pythium oligandrum oomycete is already used commercially in the form of watering and spraying. In this work the properties of other isolates were characterized, and the metabolic changes were studied in plants of oilseed rape (Brassica napus subsp. Oleifera), whose seeds were treated with preparates based on Pythium oligandrum. In the first part of the thesis the properties of compounds secreted by isolates of Pythium oligandrum were tested. The amount of phenolic substances and the activity of endoglycosidase endo-β-1,3-glucanase, cellulase, chitinase as well as proteases were measured to assess the ability of oomycete Pythium oligandrum mycoparasitically protect the plant. Substances, especially oligandrin, which during interaction with the plant are responsible for "priming", have been observed, enabling the plant to respond rapidly to pathogen infection through systemic plant resistance. Differences between individual isolates also manifested themselves in electrophoretic separation in the protein representation. In the second part of the work, the effect of rapeseed seed treatment with isolates of Pythium oligandrum on plant metabolism was monitored. While...

This thesis analyse the issue of fair trade and the posibility for this program in the Czech republic. The literary part of thesis describes the program fair trade, reasons for formation of fair trade, its current status and issue of oil palm planting in the world. This thesis evaluates influence of oil palm planting on the environment and economic, social and health impacts connected with oil palm planting for local residents and communities and impacts of oil palm production on the Czech Republic. For the practical part of thesis I used the questionnaire survey, when I examined public knowledge of the fair trade, consumer behavior, the range of demand for fair trade products and the interest of citizens about problematic situatin of oil palm planting.

This diploma thesis aims to illuminate the issue of global climate change, its progression and describes the components of the climate system. The thesis addresses the impact of greenhouse gases on the climate system, the phenomenon of global warming, and the consequences along with their manifestations in the nature itself. The paper includes one chapter solely dedicated to the characterisation of environmental protection in historical context, with emphasis on the climate protection. The chapter also mentions a number of key international agreements and conferences. The second part of the thesis is concerned with the Indonesian legislation on climate protection in Indonesia. It also describes the global-scale impacts of selected activities and mentions number of international agreements and Indonesian regulation seeking to tackle the issue of climate change.
