Title of the thesis:Evaluation of the composition of weed species in (fruit) orchards.
Summary:The aim of this thesis was the evaluation of the composition of weed species in selected orchads. The analysis and observations were carried out at two locations in the sorroundings of Šumperk. The observations at the first location in the orchard in Velké Losiny were carried out in September 2008 and in September 2009. The species composition was observed by phytocoenological survey on three defined areas: on the headland, in the spacing and around the stem. The grasses which were seeded on purpose showed the largest coverage. These were Lolium perenne, Poa pratensis and from the family of the leguminosaes Trifolium repens. From the nondesirable weeds the most common were: Crepis biennis, Taraxacum sect. Ruderalia, Cirsium arvense and Potentilla anserina. The sum of botanical species at this location was 46. The observations at the second location in Třemešek by Oskava were carried out only in September 2009. The largest coverage at this location was reached by Trisetum flavescens. The most frequent weeds were Crepis biennis, Taraxacum sect. Ruderalia, Urtica dioica and Vicia angustifolia. In sum, 69 plant species were found in this orchard.
