Influence of increased carbon dioxide concentration on grain protein composition in early and late wheat variety
 Smrčková, Kamila ; Vítová, Eva (referee) ; Hrstka, Miroslav (advisor)
This bachelor thesis deals with the effect of increased CO2 concentration (700 ppm) on the content and composition of wheat grain proteins in early (Avenue) and late (Tobak) wheat varieties. Three methods were used to determine the proteins in wheat grain: the Kjeldahl determination of crude protein content, the determination of wet gluten, and finally the gravimetric determination of gliadins and glutenins after extraction. A different response of the varieties to the increased CO2 concentration was found. The early Avenue variety was much more sensitive to the effects of increased CO2 concentrations. The gliadin content decreased, while the glutenin content increased with increasing CO2 concentration. The total gluten protein content increased in elevated CO2 concentration, independently of nitrogen fertilization. Its content correlates in our work with the content of wet gluten.
