Transport of selected metals from the soil to the plants
Šilerová, Iva ; Sommer, Lumír (referee) ; Dočekalová, Hana (advisor)
This bachelor thesis focuses on the soil, contamination of selected heavy metals and transport of heavy metals from soil to plants. The entry of heavy metals, their reactions in the soil and their transport into the plant material are described here. Lead, cadmium and copper have been selected as the studied toxic metals. There are also described methods of soil sampling, sample preparation for analysis and determination of heavy metals in the sample.

Efficiency of inquiry based teaching methods in elementary schools
PEŠKOVÁ, Šárka
The main aim of this bachelor thesis is to find out the efficiency of research-based teaching in biology lessons at upper primary school. The next partial aim is the comparison of students' effectiveness during lessons with elements of exploration-based teaching (a.k.a. experimental group) and comparison of students during frontal teaching (a.k.a. inspecting group). The bachelor thesis deals with teaching methods which can be used during students' lessons at upper primary schools and concentrates on possibilities of research-based teaching. Three research-based tasks which focus on plants and their parts (root, stalk, leaf) are suggested in the thesis. The use of these suggested tasks was verified in author's own practical training in seventh grade at one of the primary schools. Individual tasks are formed and prepared in order to develop creativity, independence, sense of co-operating and exploring stated topics with others. These suggested themes can be used during biology lessons at upper primary schools. The results of efficiency of suggested research-based tasks are presented in the bachelor thesis.

Využití alternativních postupů (homeopatie) v zahradnické produkci
Martincová, Jana
The object of this dissertation was the evaluation of influence of homeopathic remedies on qualitative and health condition of planting stock. Observed parameters were weight of aboveground part of plants and leaf surface. In the literary part is quoted the research which describes present foundation and knowledge on using of homeopathic remedies in protection of plants. In experimental part of methodology are described three experiments which were performed in the area of Faculty of Horticulture in Lednice during selected periods of years 2013 and 2014. The experimental crops were head cabbage (Brassica oleracea var. capitata) and Chinese cabbage (Brassica pekinensis). Altogether there were tested three homeopathic remedies (Carbo vegetabilis, Acidum salicylum, Silicea) in various plant-growing conditions with various number of applications. In all tested remedies during particular tests was noticed statistically significant difference.

Myrmecochory - evolutionary and ecological context
KONEČNÁ, Marie
Various aspects of myrmecochory were investigated. Effect of different storage methods on atractiveness of seeds with elaiosomes for ants was examined. Viable seed bank of refuse piles (places where ants deposit unused objects from ant nests, e.g. seeds after the elaiosome was eaten) and places outside them were compared. Chemical content of five major chemical groups, specifically amino acids, free fatty acids, organic acids, polyols and sugars, of elaiosomes and seeds of selected species was determined, and compared with respect to their taxonomic relatedness.

An Analysis of Compound Plant Names
ŠOKČEVIČOVÁ, Helena
The main objective of this bachelor thesis is to carry out the detailed synchronic analysis of compound plant names in English terminology. In the theoretical part it summarizes different approaches to the classification based on an available literature, from which the best approach to the applied analysis will be chosen. In the practical part it compares the frequency of occurrence of these categories and analyses the prevailing trends. In the final part a detailed analysis of noun-noun compound is provided, with the focus on the semantic relation between the two parts, which are not explicitly expressed in those compounds.

Nárvh ekologické sítě v katastrálním území obce Olešínky
Odehnalová, Marcela
This work deals with the definition of biotope in the cadastral territory Olešínky. The cadastral area Olešínky habitats have been identified and determine the degree of ecological stability. After the establishment of habitats is divided to physiotypes. In these bio-types were determined by plants and animals species. Species were included to the habitats according their occurrence with observation. The observation was carried out during one year. The aim of the work was to identify existing major segments with a predominance of natural landscapes and natural communities with higher biodiversity. The next task was to design a bio-centers and corridors on this area. As a result, it was found according to the degree of ecological stability in the territory under study is 0.1% of the major sites, 33.9% partially major sites and 66% of minor sites.
