The influence of water stress on selected grass species and sward botanical composition
 PAVELOVÁ, Lenka
The main goal of this thesis is to ascertain the influence of a water stress on regenerative and growth properties of grasses which were exposed to a water deficit and the influence on area composition of certain permanent grass vegetation. Assessment levels were based on container experiments. Each container contained selected class and subclass of a grass with different water regime demands. The aim of these experiments was to determine regenerative and growth abilities of chosen grasses which were exposed to water deficit and their ability to regenerate after drought during the grass branching phase. Another part of these experiments was to assess water regime impact on distribution of grasses in chosen areas. In the Czech Republic, grass vegetation is one of the basic food components for farm animals, mainly cattle, and it is an important landscaping element. It is also a component of forage industry which is a significant part of an agriculture output and the main goal in practice is to provide sufficient production of high quality,biologically valuable and healthy fodder.

The influence of water deficiency on selected fodder crops
 HRDA, Lukáš
The aim of this thesis was to assess the effect of the water deficit on selected species of perennial fodder crops ? grass and clover, as well as annual fodder crops, by comparing different species in conditions of changing climate and increasing extreme weather events, especially drought. Assesssment was based on comparing different literature and Internet data. Among the clover the following were evaluated as prospective for growing in dry weather - Onobrychis viciifolia, Lotus corniculatus, Medicago lupulina and Melilotus albus. Among the grass Festuca arundinacea and Bromus inermis proved to resist drought the best. Among the annual fodder crops Sorghum vulgare best resisted drought. In dry weather using grass and clover mixtures, which reach more balanced yields than some monocultures, proved to be more suitable. More attention should be paid to the issue of drought resistance because in the future such crops and species will be required that prove higher abiotic stress resistance, especially drought resistance.
