Studying the regulation of expression of genes involved in barley malting quality
 Hoffmannová, Viktorie ; Svobodová, Leona (advisor) ; Lipavská, Helena (referee)
Barley (Hordeum vulgare L.) is a grain cultivated as an agricultural crop across many varying climatic areas of the world. It is mainly used for its feed and brewing industry properties. This work will focus on studying the malting process on a molecular level, which mainly includes the genes for degradative enzymes of storage proteins, starch and compounds of endosperm cell walls. We shall observe how all these components interact during malting and other processes of brewing beer. It is known that malting quality parameters are tied to several genes, whose expression is regulated. These regulatory pathways will also be included in this work.

The yield formation of spring barley in depending on nitrogen fertilization
 PECA, Tomáš
The theses presents results of experiments with spring barley started in years 2017 and 2018. The experiments were put into practice at Mr Jiří Nepovím's (BSc) place in Opatovice near Světlá nad Sázavou. Laudis 550 was used as the experimental variety of spring barley and the objective of the experiment was to observe the increasing amount of nitrogen and its effect on the resulting quantity and quality. The experimental amounts of nitrogen were set to 60 kg.ha-1, 75 kg.ha-1, 90 kg.ha-1, 105 kg.ha-1 and 120 kg.ha-1. With the increasing amount of nitrogen the crop increased of 0,2 - 0,4 t.ha-1. The share of nitrogen substances in grain increased of 0,2-0,5 %.

The spring barley fertilization in terms of selected agricultural company
 ŠINDELÁŘ, Jan
This thesis presents the results of malting barley's fertilization obtained on the basis of a field experiment in an agricultural company. The aim of the work was to determine how the rate of nutrients will affect yield and malting quality. Fertilizing was based on three different rations of LAV fertilizer given to plants in an advanced phase of their growth. The rations of nitrogen were set to 20, 40 and 60 kg per hectare. The positive effect of a late fertilization was observed for yield elements. There has been an increase of the number of grains in the ear and of the weight of a thousand grains. Some malting properties were also improved. It was especially the fraction of the front grain and in part germination. But the content of N-substances exceeded the limit in two of three variants.
