Monitoring of the wheat quality for food production
Slavíčková, Radka ; Hýsková, Eva (referee) ; Omelková, Jiřina (advisor)
The aim of this study was to monitor the quality of wheat Triticum aestivum, imported into the laboratory MORAGRO after harvest by eight different suppliers, and to evaluate the main quality parameters decisive for the final use of cereal crops. The introduction of the theoretical part was devoted to understanding commercial and agricultural importance of wheat and description of morphological and physiological characteristics of wheat grain. The core of the theoretical part has been focused on the description and explanation of physical and chemical properties of the wheat grain, which largely affect the final product quality of wheat. External factors affecting final quality and yields of wheat were also commented. The experimental part was based on measurements of main quality parameters of wheat (moisture content, bulk density, falling number, amount of gluten and the wheat proteins, sedimentation value and content of additives and impurities). In most cases, measurements were carried out using automated instruments. The quality of wheat was determined based on the obtained results, which allows deciding, whether it is appropriating for food production.

The comparison of winter and spring wheat quality
UHLÍKOVÁ, Jindřiška
The theme of this Bachelor's thesis is to compare the grain quality of winter and spring wheat varieties. There were a total of 16 selected varieties, 12 of winter- and 4 of spring. The experiment was conducted on the grounds of the South Bohemian University in Ceske Budejovice. The botanic characterization of wheat, the chemist of wheat grain and the quality parameters used for examination are mentioned in the introductury part . The first part of the experiment was focused on the control during the growth, the second part documents the analysis of examined samples (mass per hectolitre, N-substances, gluten, Zeleny test, falling number).

The effect of Harvest on Wheat Quality
JOZOVÁ, Eva
This bachelor thesis deals with the influence of harvest conditions, especially the amount of rainfall, on the quality of wheat in the year of 2007. This test used a type of food wheat and the monitored quality parameters were the falling number, the amount of N-substances, the amount of gluten and the sedimentation test. Among the other parameters the test monitored the moisture, the seed quality, 1000-seed weight and the volume weight. According to the achieved results the rainfall had a negative influence on the parameters of the falling number, the sedimentation test, the amount of N-substances, the amount of gluten and the moisture. In the other parameters the influence of rainfall was not proved.
