Proso seté (Panicum miliaceum) je významným zdrojem energie a bílkovin jak pro lidi tak i zvířata. V současnosti nejsou k dispozici prakticky žádné údaje o alelopatickém účinku prosa setého. Cílem práce proto bylo zhodnotit alelopatické účinky prosa na vybrané plodiny a navrhnout možnosti využití získaných poznatků. Laboratorní experimenty zahrnovaly hodnocení vlivu extraktů z rostlinných částí prosa a semen prosa na klíčivost semen a růst vybraných druhů rostlin, dále pak hodnocení autotoxicity extraktů prosa, hodnocení vlivu různé hustoty semen prosa na alelopatickou aktivitu a stabilitu alelochemikálií prosa. Nejúčinnějším extraktem inhibujícím růst vybraných rostlin byl extrakt z mladých rostlin prosa. Avšak alelochemikálie z proso setého se nezdají být vhodné pro potalčování plevelů kvůli jejich nízké stabilitě.

Proso millet (Panicum miliaceum) is an important source of energy and protein for people and as well animals. At present, there are practically no data available on the allelopathic effect of proso millet. The aim of the work was to evaluate the alle-lopathic effects of common millet on selected crops and to suggest the possibility of using the acquired knowledge. Laboratory experiments included evaluation of the effect of extracts from plant parts of millet and millet seeds on seed germina-tion and growth of selected plant species, as well as evaluation of autotoxicity of millet extracts, evaluation of the effect of different densities of millet seeds on allelopathic activity and stability of millet allelochemicals. The most effective extract inhibiting the growth of selected plants was the extract from young millet plants. However, millet allelochemicals do not seem to be suitable for weed control due to their low stability.

The aim of the work is to evaluate the allelopathic effects of common millet on selected crops and to suggest the possibility of using the acquired knowledge.
The solution of the work will take place according to the following scheme.
1) Gathering the opinions of domestic and foreign authors on the issue and summarizing information on allelopathic effects of millets.
2) In field conditions, the stand of common millet will be established as a source of material for further work.
3) Establishment of laboratory experiments. The influence of germinating seeds, aboveground parts and their extracts on the germination of seeds of two model plants, as well as other cultivated species,
will be evaluated in the form of biotests.
4) Statistical processing and evaluation of the obtained data, as well as arrangement in the form of graph tables or image attachments.
Part of the evaluation will be a comparison of the results with the results of similar experiments in the available works and the final summary of the results obtained.
