Hodnocení růstových a sklizňových údajů kamčatských borůvek

Závišková, Lenka January 2019 (has links)
The submitted thesis on the topic of Evaluation of Growth and Harvest Data of Kamchatka blueberries is focused on the description of possibilities of cultivation and using of individual varieties of edible honeysuckle. The evaluation and monitoring of planting took place on the property school agricultural enterprise in Žabčice, the laboratory pat and the evaluation of results took place in the laboratory of Mendel University in Brno. This thesis includes characteristic of genus Lonicera L., botanical description of genus Lonicera kamtschatica L., growing demands, multiplication possibilities, description of the most famous variety and results of observation of 27 varieties of edible honeysuckle. The height of the bush, cubic capacity of bush, annual increment and phenological phases were evaluated. To harvest parameters were monitored a height, fruit width, fruit weight, fruit shape shrub yield, content of refractometric dry matter,content of ascorbic acid and the total dry matter content of the fruit. The annex of this thesis comprise graphs and tables of recording of results. During the observation, a continuous documentation was taken, and it is used in the thesis.

Stanovení vybraných nutričních faktorů v některých druzích minoritního ovoce / Vitamin C

Juráňová, Jana January 2013 (has links)
The theme of this diploma thesis is an assessment of given nutritional parameters in selected kinds of lesser known fruits, specifically 10 varieties of sea buckthorn (Hippophae rhamnoides L.), 12 varieties of cornelian cherry (Cornus mas L.) and 6 varieties of blue honeysuckle (Lonicera caerulea var. kamtschatica). Harvests of two consecutive years (2011 and 2012) were analyzed in the case of blue honeysuckle. The theoretical part was focused on historical, morphological, taxonomic and nutritional aspects of individual plants and food or pharmaceutical utilization. The considerable part of the thesis is devoted to the characterization and the possibilities of determining the contained substances, namely ascorbic acid and polyphenolic compounds, especially anthocyanins. The content of the experimental part was a description of the methods and the results of the analysis of total solids, titratable acidity, total phenolics, total anthocyanins and ascorbic acid in fruits of the selected varieties of the above mentioned fruit species. Based on the measured results, the different varieties of fruits were compared to each other and evaluated.

Srovnání plodů některých odrůd zimolezů z hlediska obsahu vybraných biologicky aktivních látek / Comparison of the fruits of some honeysuckle varieties in terms of content selected biologically active compounds

Veselý, Ondřej January 2015 (has links)
This thesis is focused to the analysis of selected varieties of honeysuckle kamtschatica (Lonicera caerula var kamtschatica) and their comparison in terms of the content of biologically active substances. There were analysed only varieties grown in 2014. Theoretical part elaborates and characterized various parameters of biologically active compounds such as phenolic, anthocyanins and ascorbic acid and possibilities of their determination. Further it briefly surveys Kamchatka honeysuckle, its taxonomic and morphological properties and its nutritional properties. The experimental part of the work was focused on the description of the methods used for the analysis of biologically active substances and their analysis. Polyphenolic compounds and anthocyanin’s were determined spectrophotometrically and vitamin C was determined by high-performance liquid chromatography. The results and varieties were compared with each other. Overall, we can say that the variety with the highest content of all three analysed biologically active substances is a variety Valchová, which had the second highest content of polyphenolic compounds (546.3 mg · 100 g-1 fruits), the third highest contend of ascorbic acid (35.1 mg · 100 g-1 fruits) and the sixth highest content of anthocyanin (170.8 mg · 100 g-1 fruits)
