The issue of water quality of bathing areas in Vltava basin and their impact on recreation
BRŮŽKOVÁ, Radka
The diploma thesis deals with the issue of water quality in bathing areas on the Vltava River. I concretely concentrated on the quality of water on dams Lipno, Orlík and Slapy. There were two aims. The first of them was observing of selected physical-chemical and microbiological indicators and algae in bathing waters of dams Lipno, Orlík, Slapy situated on the Vltava River between years 2006 and 2016. The second aim was observing of changes in water quality in the Vltava River and dams Lipno, Orlík, Slapy in the direction as river flows in the period of ten years. The thesis is divided into the theoretical and the practical part. The issue of water quality for bathing, indicators for its evaluation and the description of chosen dams on the Vltava River are written in the theoretical part. The practical part was realized by the method of the secondary analysis of data. The analysed data were gained from The National Health Institute with the permission of The Ministry of Health. The next data were given by The State Enterprise, Povodí Vltavy. The time period for the analysis was from years 2006 to 2016. Data gained were described in charts and graphs by the usage of computer programme Microsoft Excel. The part of this thesis was also the outdoor research. The gained results could be used as the source of information not only for general public but also for towns, villages or keepers of recreation facilities situated in this area. On the bases of discovered facts, data, documents, materials, outdoor research and their evaluation there will be given the complete view on the water quality in the dams intended for recreation with prediction about the future progress.

Use of autotrophic algae to production of biomass and some metabolites
Chrástová, Nikola ; Kostovová, Iveta (referee) ; Márová, Ivana (advisor)
Chlorophyll and carotenoids are natural pigments and antioxidants. These pigments are suitable for use in the pharmaceutical, cosmetics or food industries. Lipids are another major metabolite of algae and are a potential feedstock for biofuel production. This bachelor thesis deals with the cultivation of selected genera of autotrophic algae, subsequent isolation of these selected metabolites and their application. The theoretical part focuses on the description of the algae, the metabolites produced, the cultivation and the chosen methods. The experimental part deals with the optimization of the cultivation of algae of the genera Chlorella, Chlamydomonas and Desmodesmus, depending on the chosen medium and intensity of illumination, determination and quantification of algal biomass. Further, extraction of lipidic and carotenoid substances and determination by HPLC and GC was performed. In the overall comparison, the best producer of biomass is the algal genus Desmodesmus and the highest production of pigments and lipid substances was reached in algae of the genus Chlamydomonas.

Vegetable adaptogens - Schizandra chinensis
Pospíchalová, Lucie ; Půčková, Helena (referee) ; Kotlík, Josef (advisor)
This thesis deals with plant adaptogens (bioactive substances) in the plant Schisandra chinensis. The theoretical part is focused on characterization of the Schisandra genus, characterization of the Schisandra chinensis as a plant, its properties, occurrence and growing possibilities in the regional climate zone of the South Moravian Region as well as the use of this plant. Furthermore, adaptogens are described from a chemical point of view and their possible methods of isolation from individual parts of plants. The experimental part deals with extraction of fruits and leaves from plant Schisandra chinensis. Further, in the leaves extract was determined chlorophyll a, chlorophyll b and carotenoids by spectrophotometry, where the quantity of individual substances was confirmed for months April – May.

Determination of Chlorophyll Content in Birch and Pine Trees Using Hyperspectral Data
Zachová, Kateřina ; Potůčková, Markéta (advisor) ; Brodský, Lukáš (referee)
The master thesis deals with the determination of the chlorophyll content in birch foliage (Betula pendula Roth) and Scots pine using hyperspectral data. The first part of the thesis concentrates on the literature search dealing with the methods of chlorophyll content in the foliage of selected plant species. In the practical part the emphasis is on the study of spectral reflectance curves and finding their relation to the chlorophyll content from the laboratory determination. Images taken with the hyperspectral sensor HyMap and spectral reflectance curves obtained with the ground ASD FieldSpec 3 spectrometer were available. Using the derived regression model chlorophyll maps were created for Scots pine for three selected locations in the Sokolov coal basin area.

Specific water properties of pit lakes in the Czech Republic
Hrdinka, Tomáš ; Janský, Bohumír (advisor) ; Benešová, Libuše (referee) ; Herber, Vladimír (referee)
Anthropogenic lakes constitute a significant part of the Czech countryside water component which has not been given sufficient attention so far. The presented thesis deals with the assessment of variability of physico-chemical properties of water in 30 selected pit lakes in order to identify specific features associated with quarrying of different mineral raw materials, basin morphometry and trophic level of the lakes affecting the quality of accumulated water. In the second part of the thesis the author deals with the comprehensive limnological study of the Hromnické Lake with extreme water chemism resulting from excavation of pyritic shales and focuses on the phenomenon of meromixis especially. The results are based on the evaluation of physical properties of water in the lake vertical profile (temperature, conductivity, dissolved oxygen, pH, transparency and colour) and chemical analyzes of water samples collected from the surface and bottom of the lakes during the four seasons in 2003-07 (determination of Ca, Mg, Na, K, Nammon., NO3 - , SO4 2- , Cl- and alkalinity), including determination of chlorophyll-a. In the case study of the Hromnické Lake conducted in 2010-11, the analysis of hydrological regime of the lake, determination of PO4 3- , TOC, selected metals (Fe, Mn, Al, Zn, Ni, Cu, Co,...

Inter- and intraspecific variability in Vicia faba L. and Zea mays L. response to water deficit
Fridrichová, Lenka ; Holá, Dana (advisor) ; Zelenková, Sylva (referee)
This work monitors the response of plants to water deficit and subsequent restoration of water availability with the aim to expand our knowledge about plant behaviour during and after drought stress from the perspective of two plant species with a different type of photosynthesis. A particular attention was paid to the intraspecific differences and their possible changes during stress and post-stress periods. The plant response was monitored as the changes of selected photosynthetic, morphological and developmental characteristics caused by the cessation of watering for six days followed by a six-day period of renewed optimal water supply. The experiments were carried out on plants with different types of photosynthesis - C3 plant Vicia faba L and C4 plant Zea mays L.; for both plant species, three varieties / genotypes were monitored. The response of both plant species to insufficient water supply differed by the extent of changes in relative water content (RWC), chlorophyll fluorescence parameters, the dry mass of individual leaves (developed during the stress period), the ratio between the aboveground dry mass and dry mass of roots. In drought-stressed plants, downward trend in RWC was observed, as well as the increase of the minimum yield of chlorophyll fluorescence in dark-adapted leaves (F ),...

Measurements and the use of spectral reflectance of solar radiation from surface water levels
Vinciková, H. ; Pechar, L. ; Hanuš, Jan
The methodology describes measurement of spectral reflectance from the surface of water bodies and application of the measured reflectance in assessment and monitoring of water quality especially in terms of the range of eutrophication and development of water blooms. The aim of the suggested methodology is to provide an effective tool for a rapid screening of water quality situation in the Czech Republic, including relatively large areas, and therefore from more water bodies at once. This method using remote sensing allows to gather lot of data on water quality without time-consuming and overall more expensive field sampling and laboratory analysis.
