Use of LC/MS technique to analysis of some physiologically active natural compounds
Trčková, Marie ; Čáslavský, Josef (referee) ; Kočí, Radka (advisor)
Presented work is focused on application of combined instrumental method RP-HPLC/ESI-MS in analysis of several groups of natural compounds with positive physiological activities. Especially some antioxidants were studied in commonly and abundantly consumed food. Moreover some other substances than standard compounds were observed in complex dies. In conclusion the HPLC/ESI-MS method is comparatively advantageous in phenolic analysis, while another type of ionisation would be used in case of carotenoid compound.

Foliar fertilizers containing collagen hydrolyzate for nutrition of grapevine: applied methodology with certification
Horák, Jaroslav ; Raimanová, Ivana ; Kurešová, Gabriela ; Trčková, Marie
A comprehensive methodology describing the use of products made from collagen hydrolyzate for leaf nutrition of main field crops and vines grown in conditions of organic farming as well as within the conventional method of cultivation. Elaboration of the methodology was preceded by applied research to develop environmentally acceptable ingredient - collagen hydrolyzate, where undesirable sodium is replaced by biogenic, often scarce potassium. Another objective was to optimize content and a mutual ratio of trace elements from the perspective of requirements of particular crops or their groups. Within the methodology are stated all the information needed for qualified decision-making regarding to foliar application of newly developed products in organic and conventional mode of farming. Examples of practical use of both types of fertilizers are the result of their application in field trials and South Moravian vineyards with standard and biological growing system.

Možné ovlivnění českého venkova současnou mezinárodní migrací
Trčková, Marie
Migration is a global trend not only of the current population. However, it bears many controversial questions that are not easy to answer. Currently, opinions regarding the arrival of Syrian refugees into Czech Republic are dividing our society across generations and social status. This diploma thesis is mainly focused on the possible influence of Czech countryside by this migrant wave exhibiting totally different cultural behaviour. Moreover, the differences among Syrian culture and global Islamic religion as well as the Vietnamese traditions, we live in the Czech Republic alongside for decades, are discussed. A survey was conducted to determine the public perception among people living on rural areas with respect to a hypothetical arrival of refugees to their village. The main feature of the questionnaire was identified as the scepticism of respondents concerning the refugees integration process, whereby the vast majority was afraid of arrival of war refugees into Czech country. Additional analysis is attempting to identify possible sources of the negative attitude of the population. Finally, the work was enriched by view of a leading Czech expert on geomigration, assoc. Prof. Dr. Dušan Drbohlav.

Foliar nutrition of cereals
Trčková, Marie ; Raimanová, Ivana ; Svoboda, Pavel
Methodology provides information on physiological aspects of foliar nutrition of plant; it deals with importance of foliar fertilizers and additional plant agents in nutrition system of cereals. Moreover it describes main principles of application of leaf fertilizers. List of foliar fertilizers intended for cereals and features of additional plant agents are integral part of this methodology.
