Study of plant stress responces in presence of pharmaceuticals in cultivation medium
Bystroňová, Jana ; Soudek, Petr (advisor) ; Podlipná, Radka (referee)
The aim of this study was to verify the possibility of ibuprofen degradation by selected plant cultures and determination of activities of antioxidant enzymes (peroxidase, catalase, ascorbate peroxidase and glutathione-S-transferase) as markers of oxidative stress caused by ibuprofen. Nicotiana tabaccum (cv. La Burley 21, cv. SR 1 and their GMOs) and Nicotiana glauca were used as experimental plants. The rate of removal of ibuprofen tested by tobacco was decreasing in the following order: N. tabaccum SR1 > N. tabaccum Zm-P60-1-T4 > N. tabaccum TRI 2T2 > N. glauca > N. tabaccum TRI 2T1 > N. tabaccum cv. La Burley > N. tabaccum Zm-P60-1-T5. As the most suitable tobacco for the removal of ibuprofen seemed untransformed N. tabaccum SR1. The long-term experiment showed that plant stress is being manifested even after longtime. N. tabaccum cv. La Burley 21 seemed to be the most tolerant to ibuprofen in compare with the total enzyme activities in cultures with the presence of ibuprofen and controls. N.glauca was the least tolerant cultivar. Keywords: phytoremediation, ibuprofen, Nicotiana tabaccum, Nicotiana glauca, HPLC, peroxidase, catalase, ascorbate peroxidase, glutathion-S-transferase

The technology of cultivation and fertilization of barley (Hordeum) for the manufacture of food supplements' green barley ".
DARDOVÁ, Magdaléna
The aim of this thesis was to study the technology of cultivation and fertilization of barley (Hordeum) for the manufacture of food supplements' green barley ". The main active ingredients in green barley enzymes are superoxide dismutase, catalase, peroxidase, cytochrome oxidase and transhydrogenase. Other ingredients are flavonoids saponarin, glykosylisovitexin and lutonarin. In producing research was determined the best technology for cultivation and fertilization of green barley. Most substances contains barley grown in organic farming. On the contrary, this barley has a higher content of nitrates due to the exclusive use of manure, which are nitrogen-potassium, and in such a system is a factor in low phosphorus. According to the Liebig law nitrogen which is not in balance with the element in the minimum, it is not able to transform plant nitrogen organic substances. From a nutritional point of view seems to be the best ecological cultivation of barley on dry freshwater lakes in the USA. The soil in these areas contain enough nutrients for barley, which is a prerequisite for good quality products. If green barley grown in the Czech Republic, it would be most appropriate cultivation conventional manner. The soils are poor in nutrients, and thus would only manure was insufficient. The increase of the active substances it is appropriate to use any of several kinds of elicitors. The most suitable varieties would malting barley varieties Sebastian, which includes most of the active substances.
