Vplyv spontánnej a riadnejs technológie na obsah biogénnych amínov v bielych vínach
Blšáková, Lucia
The diploma thesis deals with the influence of spontaneous and controlled technology on the creation of biogenic amines. In the literary part, it deals with the properties, origin and their occurrence. It further describes the various factors and microorganisms that influence their creation. Consequently, it focuses on the effect of biogenic amines on health and factors that may increase their toxicity in the microorganism. At the end of the literature search, describe focuses on the creation of biogenic amines in wine, their content in world wines and focuses on oenological factors affecting their content. The experimental part describes the Chardonnay experiment procedure in detail. It was divided into four variants. Two of them were technologically processed in the barrel, the other two in a glass container. Subsequently, both versions in the barrel and in the glass were divided into a production process processed by spontaneous and controlled technology. Samples were sampled during the experiment and then analyzed analytically by HPLC for the formation of biogenic amines. The resulting wines were sensory evaluated. All results were statistically processed and compared with studies dealing with similar issues.

Významné české a slovenské novošľachtenie
Blšáková, Lucia
This bachelor thesis first deals with the history of breeding in Slovakia and Czech. Origin, development and, in short, important personalities.It also describes brewery stations from their history to the present.Later, the work describes the systematic classification of the genus Vitis L., its Euvitis and Muscadinia subdivisions, and Euvitis subdivision into three groups - North American, East Asian, Eurasian. The thesis briefly describes the composition of the fruit of the vines (inflorescence, flower, straw, berry, seed) and fertilization and fruit formation. In the next chapter it deals with soil and climatic conditions of vineyard areas in Slovakia and Czech republic.It also provides information about breeding and its aims, breeding methods, new methods of breeding, mutation, insult and heterosis, polyploidy and clonal selection. In short, the work describes modern methods such as in vitro methods and cellular culti-vation, which include GMO plants. It focuses on resistance that plays a key role in bre-eding.The remaining chapters focus on genofonds in both countries and on their signi-ficant new varieties and their representatives. Grape varieties such as Devin, Dunaj, Hetera, Torysa, Rosa, Malverina, Muškát Moravský, and so on, such as Premier, Olša-va, Pola, are described here.
