Determination of selected metals in unconventional fruit species
Křížová, Soňa ; Dočekalová, Hana (referee) ; Diviš, Pavel (advisor)
The aim of this diploma thesis is determination of selected metals in unconventional fruit species, specifically in cornelian cherry (Cornus mas), sea buckthorn (Hippophae rhamnoides) and medlar (Mespilus germanica).There is informationabout 16 analysed metals – As, B, Be, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Se, Sn, Pb, V, Zn. There are described analytical techniques for elemental analysis and methods for destruction biological material. Samples for analysis are prepared by using microwave mineralization and ICP-MS for detection. This is described in the experimental part of the diploma thesis. Analysis confirmed that unconventional fruits are rich sources of trace elements.

Využití méně pěstovaných ovocných druhů pro zpracování
Vincentová, Martina
Bachelor thesis is focused on the possibility of growing and processing Chinese hawthorn (Crataegus pinnatifida Bunge.) and Chinese jujuba (Ziziphus jujuba Mill.). The origin, morphological description, cultivation, ecological requirements, propagation, harvest, health effects and food utilization of these fruit trees is described in this thesis. Japanese persimmon (Diospyros kaki Thunb.), Asian pear (Pyrus pyrifolia (Burm.) Nak. 'Hosui'), Hardy kiwi (Actinidia arguta (Siebold & Zuccarini) Planch. Ex Miq.), Sea buckthorn (Hippophae rhamnoides L.) and Mountain-ash (Sorbus aucuparia L. 'Sorbinka') are describe too. From the harvested fruits were produced conserves, marmelades and other products, which have been assessed during the tasting. Top rated was a jelly with hawthorn and hardy kiwi, then marmalade from jujuba, rowan berries and compote from jujuba and hawthorn with alcohol. Based on the evaluation was found that all products were evaluated above average. Products have positive sensoric qualities, significant health effects and are easy to produce. Therefore, the possibilities of domestic production are very wide.

Možnosti pěstování rakytníku řešetlákového v podmínkách ČR
Hynek, Petr
This thesis deals with the evaluation of the available books and possibilities of the growing of sea buckthorn (Hippophaë rhamnoides L.) in the Czech Republic. Physical and chemical values which are necessary for planting sea buckthorn in the area of Lednice were measured and specified. The female plants of the species of ´Buchlovsky 1´, ´Hergo´, ´Leikora´, ´Vitamínová´, and the male plant of ´Buchlovsky 2´, ´Pollmix´ and ´Ruský´ were studied and evaluated. As for the products made of sea buckthorn, speads and juices with various amount of sugar, baked tea and sweetened sea buckthorn powder were evaluated from the sensory point of view. The issues of the growing and processing of s ea buckthorn were discussed with the producers of planting stock, commercial croppers and manufacturers within the whole Czech Republic. Sea buckthorn is not widespead and commercial area for growing does not meet the needs of the manufacturers. If all biotic and abiotic factors are taken into account, the growing of sea buckthorn is recommended in the Czech Republic.

Růstová charakteristika souboru odrůd rakytníku řešetlákového
Chelíková, Hana
The object of Growing characteristics of sea buckthorn varieties was to elaborate the list of literary sources considering origin and expansion of the plant. Define environmental conditions for growth and possibilities of utilization of the fruit. The experimental part of the work took place at the School Farm in Žabčice. The data of the above-ground growth of each variety of the monitored plants was recorded. The annual growth, height, width and volume of the bushes were evaluated, further also the shape, thorning and branching. The data was further processed. Suitable varieties for growing in our climatic conditions were recommended being based on the evaluated results.
