Title of the thesis:Study of the effect of selected enviromental conditions on the weed seeds germination
Summary:The aim of this thesis was to find out the influence of temperature on germination of Tripleurospermum inodorum seeds. Seed germination took place in laboratory conditions. This thesis is based on two laboratory experiments. During the first experiment, the effect of different temperatures on the germination of Tripleurospermum inodorum seeds was observed. During the second experiment, it was observed how would the Tripleurospermum inodorum seed germinate if it was exposed to freezing temperatures for various periods of time. The seeds germinated best at 20 °C. At this temperature, germination was 92.5%. During the second experiment, the best germination was 74.5%. It was with seeds that had been exposed to frost for thirty days. Results have been written to the tables and processed to graphs. In addition, germination results were compared to other weed species. Evaluation of the thesis is given in the discussion.
Key words:Tripleurospermum inodorum, germination, temperature, seeds, weed
