The bachelor thesis of the theme: The Vegetation Species Composition at Selected Section of The Railway Line evaluates species composition at railway section Moravské Bránice. The observations took place in the twelve places, at the abandoned rail, the semioperating rail, the operating rail and in three terms: 1st May, 20th August and 30th October, in 2016. The species composition was evaluated by using the phytocenological images. The obtained data were subsequently processed by statistical analyses DCA and CCA and their output was ordination diagram expressing the relation of weeds and the way of the railway use. Total amount of found plant species was 46. Most species were discovered in spring, at the abondoned rail. Over the period under review, the highest level of coverage was reached by: Holosteum umbellatum, Trifolium repens, Amaranthus retroflexus, Poa annua, Digitaria sanguinalis a Linaria vulgaris.

The diploma thesis: Study of Selected Physiological Features of Field Weed Populations from Different Habitats investigates the effects of temperature and habitat influences on seed germination of redroot pigweed Amaranthus retroflexus and German chamomile Matricaria chamomilla. Seeds of redroot pigweed were collected from the habitats: field margin, tree alley, railway and field. Seeds of chamomile were collected from the habitats: field margin, tree alley and were also bought. The seeds were exposed to temperatures 6 °C, 8 °C and 18 °C.The highest seed germination of both species was at 18 °C and the lowest was at 6 °C. The highest seed germination of redroot pigweed was recorded from the „field margin“ habitat 34,67 % and the lowest seed germination from the „field“ habitat 28,67 %. The highest seed germination of German chamomile was recorded from the „bought“ habitat 86,67 % and the lowest seed germination from the „field margin“ habitat 34 %.
