Study of selected technological properties of licorice mass
Gajdušek, Martin ; Vítová, Eva (referee) ; Vespalcová, Milena (advisor)
This bachelor thesis deals with the study of selected technological properties of liquorice matter. By microscopic observation it was found that at a content of more than 10% of the boiled starch grains or more than 30% of the non-swollen grains, the mass does not achieve the desired properties for further processing. Technological loss during drying depends mainly on time, but also on location in the oven, both in height and space. The highest technological loss was achieved mainly in the highest positions in the oven. By liquid chromatography was determined 11.8% glucose, 9.2% fructose, 23.3% sucrose in liquorice mass prior to cooking; 11.9% glucose, 9.4% fructose, 22.6% sucrose in cooked matter; 12.7% glucose, 10.8% fructose and 20.1% sucrose in dried liquorice products.

Ultrastrucutre of beech chloroplasts under the elevated CO2 concentration and different irradiation
Vrbová, Anna ; Albrechtová, Jana (advisor) ; Kutík, Jaromír (referee)
Forest stands may act as important carbon storage places - sinks, due to carbon allocation into both the plant biomass in the process of photosynthesis and the soil. Enhancement of CO2 concentration affects a whole range of plant physiological processes and, thus, it is necessary to study its effect on photosynthetic apparatus - leaf anatomical structure and chloroplast ultrastructure. The first aim of the Thesis was to evaluate changes in chloroplast ultrastructure of common beech (Fagus sylvatica L.) under the effects of both elevated CO2 concentration and different irradiance. The second aim was to evaluate if the anatomical parameters obtained from the middle part of the leaf are representative for the whole leaf blade. The trees were grown in glass domes at the Bílý Kříž experimental site in the Beskids Mountains (Czech Republic), owned by the CzechGlobe Institute. Leaves were sampled in 2010 from juvenile trees, which were planted in 2005 being 5-year old and cultivated since then in ambient (AC; 390 micromol/mol) and elevated (EC; 700 micromol/mol) CO2 concentrations. The EC effect was recorded to be an increased proportion of starch grains in the chloroplast median section and decreased proportion of of intergranal thylakoids (IGT) while the ratio of granal to intergranal thylakoids...
