Abstract A basis for the identification of potential tourist development areas was defined as a combined use of the model of area load by visitors, the territorially-located database of tourist attractions, and the perception of their attractiveness by visitors. A distinctive inequality was identified in the area load and the distribution of tourist attractions. The areas of development were determined on the basis of a difference between the relative attendance and the relative attractiveness of the partial territorial units of a regular hexagonal network, sized approximately 3 km2, with a concurrent requirement of above-average total attractiveness

Milk thistle is grown in the Czech Republic as a medicinal herb; silymarin is isolated from its achenes and used for the production of liver and gallbladder medicine. The quality and content of the active compound is influenced not only by environmental factors, but also by pests and pathogens. The occurrence of pests of milk thistle variety Silyb was observed in two localities during the years 2011 2013. In the year 2011 the mycoflora of seeds of four milk thistle varieties was determined. Representatives of 15 species were isolated from the seeds, most of them saprophytic. 21 fungal species were isolated and identified from milk thistle plants during the vegetation; Septoria silybi among the most important ones. Possibilities of protection of milt thistle against pathogens are discussed.
