Determination of selected metals in grapes cultivated by different techniques
Kubicová, Lenka ; Vespalcová, Milena (referee) ; Diviš, Pavel (advisor)
The aim of this study is to determine the content of selected metals (As, Ba, Cd, Co, Cr, Cu, Mn, Mo, Ni, Se, Sn, Sr, Pb, V, Zn) in samples of leaves and grapes produced by ecologic agriculture and compare to results with leaves and grapes produced by integrated agriculture. The measured results used to assess the impact of agricultural technology on the quality of vines and grapes. The amount of elements was analysed using inductively coupled plasma mass spectrometry after previous digestion of sapmles using microwaves. Concentrations of elements in leaves and grapes from organic and integrated farming did not differ significantly only in the case of copper concentrations were measured higher concentrations in samples from organic farming. This difference is probably caused by different doses of authorized protective equipment based on copper in the organic and integrated farming.

Selected forms of Selling the Organic Food - Retail Chains
JEŽKOVÁ, Zdeňka
The main aim of my thesis was to assess the current state of organic food selling in retail chains in terms of assortment range, requirements and sale culture and to suggest appropriate measures based on the data obtained. The theoretical part is focused on defining the concept of organic farming, through organic products right to organic food. The empirical part is focused on the evaluation of the supply list with specific types of organic products offered in individual stores, comparing the offer of organic food between retail units, and finally comparing the offer of organic food within the former districts. The analysis contains also summarized findings resulting from a questionnaire survey among retail business organizations. The conclusion of the empirical part is focused on answering presented hypotheses and proposing recommendations.

The sale´s analysis of organic food within retail chains - regional aspects
MEDEK, Josef
The principle aim of the diploma thesis is to analyze sale of organic food within selected retail chains. Specifically, it is determination of the sale strategy, assortment structure, conditions and culture of the organic food sale. The thesis comprises a part of the MSM 0652104020 research project of the College of Economic of the South Bohemian University.
