Transport of humic substances into leafs
Žáková, Michaela ; Kalina, Michal (referee) ; Klučáková, Martina (advisor)
This bachelor thesis simulates leaf foliar fertilization and describes transport processes of humic substances. Experiments were performed for two areas. The first focused on the flow through the plant cuticle as the main selective barrier. In the second one the transport of humic substances to the leaf was studied. The diffusion process was evaluated by the concentration loss of lignohumate solutions, which served as the medium of humic substances in the solution - leaf model. The results showed the effect of cuticle on nutrient penetration and its dependence on its condition. New findings are the transfer processes of humic substances into the leaves, that have proved effective in a short period of time, mainly at higher concentrations.

The media image of the Carnation Revolution in the Czechoslovak period press
Lukášová, Kateřina ; Končelík, Jakub (advisor) ; Cebe, Jan (referee)
This bachelor thesis is focused on an analysis of the Portuguese Carnation Revolution that took place on April 15, 1974 and its media image in the Czechoslovak press of that time. The Carnation Revolution was a non-violent military coup that overthrew the long-term dictatorial Estado Novo regime and started the process of democratization. This process faced many challenges, it took two years to form a democratically elected parliament that approved the constitution of the newly formed Portuguese Republic. The aim of this bachelor thesis is to compare the interpretation of the Carnation Revolution and its key moments, that threatened the democratization process, in the Czechoslovak newspaper Rudé právo with historical sources to determine whether the official party press of the Communist Party of Czechoslovakia deviated from them in order to glorify the Portuguese Communist Party and their actions in the Provisional Government. At the same time, this thesis compares the interpretation of the Portuguese regime transformation in exile press Svědectví and Listy. The analysed events are: the Carnation Revolution (April, 25 1974), the September attempt of a political coup (September, 30 1974), the March attempt of a political coup (March 12, 1975) during the democratization process and the formation of...

Hodnocení produkční schopnosti jitrocele kopinatého pro pícní využití
Valigurová, Jana
Dycotyledonous herbs for forage use are more often being used in agriculture. This diploma thesis focuses on one of the variants, namely ribwort plantain, which is considered a high-quality fodder and whose main feature is the ability to withstand abiotic stresses and provide high forage production even in the dry season. With the increasing frequency of drier periods, ribwort plantain has got great potential to become a more grown crop. Therefore were cultivated varieties of ribwort plantain, which provide higher yields and are more resistant to adverse climatic conditions than common flatweed type. The practical part of this work is divided into two parts. The first part of the experiment was grown in sand rolls, where the production of rootstock biomass of ribwort plantain (cv. Tonic) was compared with four other species: chicory (cv. Puna II), red clover (cv. Callisto), festuca arundinacea (cv. Kora) and alfalfa (cv. Zuzana). This experiment was set up in September 2019 and the total lenght of vegetation was 69 days, the experiment was fertilized twice during the vegetation. Leaves heights of all species were written down during the vegetation. After the end of the vegetation there was evaluated total lenght of the roots, the maximum depth of the roots and the length of the roots based on their thickness. These parameters were evaluated via WinRHIZO program. The maximum of root depth (18,2 cm) and root length in total (2 032 cm) were demonstrated for Tonic plantain. The second part of the experiment focused on the evaluation of the production capacity and the production of the root biomass of ribwort plantain took place on experimental plots at the Forage station in Vatín. This experiment was set up in June 2019 in three variants, where three following species where sown: ribwort plantain (cv. Libor), chicory and a mixture of plantain, chicory, cocksfoot, perennial ryegrass, meadow fescue, Kentucky blue grass, timothy, white clover, birdsfoot trefoil. A statistically significant difference was found only in the dry matter yield and the dry matter content, where lower values were written down for plantain Libor than for the grass mixture (dry matter yield lower by 0,45 t.ha-1, dry matter content in the first mowing lower by 5,06 %, in the second mowing lower by 2,22 %). There was also evaluated the content of crude protein (15,87 %) and fibre (ADF 22,58 % and NDF 26,77 %). In the spring 2020 was evaluated the production of root biomass like in the first part of the experiment using the WinRHIZO program. In plantain Libor there was found higher density of rooting in the upper layer of the soil (10,2 cm.cm-3) than in chicory (3,1 cm.cm-3).

Literární noviny, Literární listy and Listy (1966-1969): The story of the demise of the Union of Czechoslovak Writers' weekly
Čáp, Johan ; Čeňková, Jana (advisor) ; Končelík, Jakub (referee)
This bachelor's thesis aims to describe the functioning of a weekly Literarni noviny, one of the most influential periodicals in Czechoslovakia in the 1960s. Between 1966 and 1969, the publication of this cultural magazine was stopped twice and Literarni noviny was renamed twice - first to Literární listy and later to Listy. In the theoretical part, the thesis deals with the phenomenon of cultural magazines in the 1960s, the functioning of censorship in Czechoslovakia, and important topics with which the periodical influenced contemporary discourse. In the practical part, using qualitative methods - historical-comparative analysis and text analysis - summarizes the content and graphic changes of the periodical in individual stages, and puts everything in context with other cultural periodicals of the time. Part of the bachelor's thesis is also an oral history interview with Vladimír Karfík, then editor-in-chief of the cultural section of Literarni noviny. The conclusion of the thesis shows the periodical changed structurally relatively little between 1966 and 1969 and the changes in content corresponded to the progress of media liberalization - the tightening or loosening of censorship. The unique interview with Vladimír Karfík complements some details that do not appear in the literature and is a...

Diversity and ecology of endophytic fungi in different parts of pants.
Kovaříčková, Adéla ; Prášil, Karel (advisor) ; Kolařík, Miroslav (referee)
Even though endophytic fungi have been studied intensively in the past years, little attention has been payed to endophytic colonisation of a whole plant. The search part of this work is about the differences in diversity and ecology of endophytes within whole plants, whose single parts represent qualitatively different environments for growth of endophytic fungi. The main difference is between the colonisation of systemic endophytes of grasses from family Clavicipitaceae and the colonisation of taxonomically heterogenous group of non-systemic endophytes. A systemic endophyte colonizes all above-ground organs of grass, while a non-systemic endophytes form only local infections, and their species composition in specific plant parts differs. The practical part of this work encompasses the pilot study of species diversity of endophytic fungi from woody parts (branches, stems and roots) of an elm tree (Ulmus laevis). There are differences in the frequency of colonisation among samples cultivated on agar plates, and also in diversity of isolated fungal genera.

Roma locuta - causa finita. Authority of the Roman Bishop in the beginning of the 5th century seen through the letters of Innocent I
Trepeš, Ondřej ; Vopřada, David (advisor) ; Ventura, Václav (referee)
The thesis presents firstly the political and historical situation in the Late Roman Empire in which the Church was granted liberty. Through the historical events is shown how the theological discussions were jointed and influenced by the contemporary political situation of the Empire. Secondly, the life of the Pope Innocent I before and during his pontificate is presented and Nachleben of Innocent as a saint man, the style of his letters is involved too. In the same chapter is his pontificate described and discussed through letters, which he sent to various groups of bishops. These are divided into the following groups: Eastern bishops, bishops in Europe, boshops of Africa and the letters as a support for his friend John Chrysostom. In all these fields Innocent treats self-confidently, with the authority of the Roman bishop, but the kinds of claims to his authority depends on geographical location in which the letters are sent. Alongside the contribution of the basic introduction to the letters of the Pope Innocent I this thesis also offers the short excursion to the philological analysis and the selected theological topics (especially liturgical) of his letters.

Determination of zinc, cadmium and nickel in leaves by inductively coupled plasma-mass spectrometry
Plodík, Michal ; Hraníček, Jakub (advisor) ; Červený, Václav (referee)
Práce je zaměřena na stanovení těžkých kovů (zinku, kadmia a niklu) v listech různých druhů stromů. Vzorky byly odebrány z různých lokalit na území České republiky. Pro analýzu byla použita hmotnostní spektrometrie s indukčně vázaným plazmatem, která je dostatečně citlivá pro předpokládané nízké koncentrace vybraných kovů. Pro stanovení koncentrace byla klíčová příprava vzorků pro mikrovlnný rozklad v koncentrované kyselině dusičné. Naměřené koncentrace sledovaných kovů se lišily nejen mezi lokalitami a jednotlivými rostlinnými druhy, ale také v rámci jedné lokality. Použitá metoda ICP-MS prokázala dostatečnou citlivost i u prvků s přirozeně nízkou koncentrací v životním prostředí, což bylo v této práci kadmium.

Jan Štern: His life and Work In and After the Communist Era
Krejčíková, Žaneta ; Knapík, Jiří (advisor) ; Štoll, Martin (referee)
This diploma thesis studies the life story of czech journalist Jan Štern and analyzes his articles in the magazine "Listy", which was illegal in the former Czechoslovakia until the end of 1989. The main goal is, in addition to the description of Štern's life when he went through the concentration camp, the Prague Uprising and the revolution against the communist regime, to find answers of research questions: "Do the texts encourage the reader to do something specific, if so, to what?", "What is the nature of the texts: descriptive, entertaining, contemplative, reviewing or dictating?" and "What is the focus of the texts, are they of a purely political nature?". The evaluation was based on a combined content analysis of 62 articles from the 70s and 90s of the 20th century and the results show that 74 % of the texts do not contain a direct call or persuasion, 79 % of articles can be described as a contemplation or combination of contemplation and description and every arcticle responds to a political issue. The whole work ends with a conclusion, a list of used sources, theses, a list of appendices, bibliography of used articles from the magazine "Listy" and transcription of interview with Anna Šabatová.
