Cereal in the medieval culture of the Czech lands
Freiová, Kristýna ; Czumalo, Vladimír (advisor) ; Hubáček, Ondřej (referee)
Agriculture makes its first appearance in human history about 12 000 - 5 000 years ago. Around that time, people took to a sedentary way of life so they could primarily till the land and grow the grains which they had come to know in their wild varieties. This new way of life gradually changed the social and cultural order. A return to primeval living was not impossible, though. Before the Slavs arrived on the territory of what is today Moravia and Bohemia, various Indo-European tribes had already pursued agriculture in our part of the world, chief among them the Celts and the Germans. The Slavs, which came from the eastern part of Europe, probably in the second half of the 6th century, built upon the farming of these erstwhile peoples. After the rise and fall of proto-states, for which evidence has survived only in the case of Great Moravia, an early Bohemian state took hold. In the local culture, grain played an indispensable role. Farming was the main livelihood of the entire populace. Crops of choice at the time were millet, einkorn, and emmer wheat, which gradually gave way to common wheat and barley. The land was tilled with wooden hoes which merely cut furrows in the soil. The grain, which was harvested using sickles, was stored in pits in the ground. To improve digestibility of the grain...

Hodnocení růstových a sklizňových údajů netradičního ovocného druhu - dřínu obecného
Shromáždil, Filip
This thesis examines the growth and harvesting characteristics of the non-traditional fruit species of dogwood. The work in the explanatory section deals with the origin of this fruit shrub, its distribution, the demands it makes on the environment, its growth properties and propagation technology. Then it describes the chemical composition of the fruit and possibilities for using it in the food industry or in horticulture. The selection of six dogwood species (´Elegant´, ´Fruchtal´, ´Jolico´, ´Lukjanov´, ´Vydubec´ and ´Vyshegorod´) was evaluated at an experimental area of the breeding institute in Zabcice. For each variety, we examined and compared the extent of the phenological phases, the size of the bush volume, the size of the fruit harvest and both external and internal features of the fruit. This last observation involved evaluation of the length, width and weight of the fruit, the proportions and weight of the stone, plus the levels of vitamin C, dry matter and refractometric dry matter. The results obtained from the measurements were processed and statistically evaluated. Through a combination of our results and reference to expert studies, we are able to recommend the most suitable varieties for cultivation under our climatic conditions.

This bachelor thesis is focused on ascertaining of the growth and harvesting properties and subsequently on evaluation of phenological phases of a few varieties of Cornelian cherry (Cornus mas L.) in the growing season 2016. The thesis includes the general part dealing with the history, origin and distribution of the species, the method of propagation and cultivation. It also discusses the importance of the nutritional value of the fruit and its chemical content. The thesis also contains an information about the possibility of using Cornelian cherry in ornamental ladscaping and food processing industry. The experimental part of the work was secured on an experimental plot in Žabčice. I evaluated fice varieties of Cornelian cherry (Fruchtal, Vydubecký, Vyšegorodský, Lukjanovský and Elegantní). Phenological phases of different Cornelian cherry varieties were observed. Furthemore, there was carried out the measurement of growth parameters (cubic bushes, fruit size) and evaluation of harvesting parameters (yield of plants, weight of individual fruits). I assessed pomological characteristics, determined the content of vitamin C and evaluated the taste of the fruit of the individual varieties. Overall results of the measurements were processed and evaluated statistically. The obtained values were arranged in tables, diagrams and described in detail. According to the determined values we can pass on an information about the best variety for cultivation and subsequent processing. Cornelian cherry among rarely widespread fruit species in the Czech Republic. Because of his modesty during cultivation, resistace to pesticides and diseases and high nutritional values it could be further exploited again. New and interesting varieties of fruit are being growned. Also, a more appropriate method of growing on the trunk is used. This advance in growing could be beneficial for extending of this kind of fruit.
