Nollová, Kateřina
The aim of this master thesis is to compare cultivars of asparagus lettuce (Lactuca sativa L. var. angustana L. H. Bailey) and Indian lettuce (Lactuca indica L.). Five cultivars of asparagus lettuce and one cultivar of Indian lettuce were included in the experiment. Morphological parameters, yields and content substances (vitamin C, carotenoids, nitrates and dry matter) were evaluated. The experiment was successfully carried out on the grounds of the Faculty of Horticulture in Lednice in years 2015 and 2016. Contents of vitamin C, carotenoids, nitrates and dry matter were subsequently evaluated in a laboratory. The share of domestic production in the total consumption of vegetables in the Czech Republic could be enhanced by expanding the range of other, valuable, Asian asparagus and Indian lettuces.

Hodnocení perspektivních zelenin z hospodářského a nutričního hlediska
Sodomková, Martina
This diploma work consists of the study of chosen species of vegetables of an Asian origin. The focus is put on the technology of growing these vegetables and also on their nutritive qualities. Three species of pigweed (Amaranthus sp L.), two species of asparagus lettuce (Lactuca sativa L. var. angustana L. H. Bailey), indian lettuce (Lactuca indica L.), common purslane (Portulaca oleracea L.), jewels of opar (Talinum paniculatum (Jacq.) Gaertn.) a sweet corn (Zea mays L.) were included in the experiment. The evaluation of growth and profit parameters was made and furthermore, the evaluation of important content elements such as the Vitamin C, antioxidation capacity, the content of minerals et cetera. The experiment was carried out in the area of Faculty of Horticulture in Lednice in 2014. Based on the results of the experiment the differences between the growth demands of each vegetable species were recognized, as well as the differences of the content elements of each species. As all species were successfully cultivated, we can claim that these types of vegetables are capable of acclimatizing to the conditions of the Czech Republic. Regarding their content they are diverse species with a wide utilization. pigweed, asparagus lettuce and common purslane in particular, have proved to be perspective species of vegetables with an easy growing method and wide nutritive values.

Vyhodnocení perspektivních genových zdrojů zeleniny z Asie
Svátková, Kateřina
Diploma thesis deals with the vegetable species and varieties of Chinese seed companies. Development of individual vegetable items, nutritional composition, morphology and growth parameters were observed for seven vegetables species during year 2013. Observed vegetable species were: Pigweed (Amaranthus sp L.), Chinese cabbage (Brassica rapa L. subsp. pekinensis (Lour.) Hanelt), Asparagus lettuce (Lactuca sativa L. var. angustana L. H. Bailey), Indian lettuce (Lactuca indica L.), Basil (Ocimum basilicum L.), Common purslane (Portulaca oleracea L.) and Jewels of Opar (Talinum paniculatum (Jacq.) Gaertn.). Pigweed was evaluated in three varieties, Chinese cabbage and Asparagus lettuce in two varieties. Other species were represented by only one variety. Perspective vegetable species were recommended for the Czech Republic based on the results of successful experiment. Interesting and perspective species were Pigweed, especially the variety 'Beijing amaranth No. 4' ,,green", Asparagus lettuce, item (46), Indian lettuce, Common purslane and Jewels of Opar, not only because of easy cultivation, but also because of the number of constituents. Chinese cabbage and Basil were also cultivated very easily, but bigger attention should be focused on new or lesser-known species in Czech Republic.
