Agricultural production faces with ongoing climate that in Europe takes form of changing seasonal precipitation pattern with more frequent drought spells. These changes come on top of rising air temperature and did and will affect productivity as well as onset and duration of key developmental stages for yield formation of major staple crops such as wheat. In order to ensure stable agricultural production and satisfy demand of the increasing humanpopulation, it is crucial to know responses of major field crops to these abiotic stress factors to assess suitability of genotypes to specific environmental conditions. The aim of this study was to evaluate final yield formation parameters of five winter wheat genotypes cultivated in pots and exposed to two different levels of CO2 concentrations (400 ppm as ambient and 700 ppm as elevated CO2 concentrations) and two water treatments (well- watered control and drought-stressed plants). Theexperimental treatments were set up in growth chambers from the end of heading stage (BBCH 59)to the beginning of ripening stage (BBCH 71) to simulate the conditions under future climate. The results showed that elevated CO2 concentration led to: (1) mitigation of reduction in final yield formation parameters of drought-stressed plants compared to those of control, (2) enhanced results of drought-stressed treatments compared to those of drought-stressed treatments exposed to the ambient CO2 concentration. Pannonia NS was found out as the less responsive genotype to the exposition of CO2 concentration (no statistically significant differences among ambient and elevated CO2 concentrations in all yield formation parameters were identified). On contrary, harvest index of genotype Bohemia was identified as the most sensitive parameter in response to drought stress as well as to the atmospheric CO2 concentration.
"Nosotros no bailamos así": Salsa as globalized and commercialized phenomenon in the local context
Smutná, Petra ; Halbich, Marek (advisor) ; Skořepová, Zita (referee)
This thesis deals with the musical and dance style known as "Salsa" which roots can be traced to the Caribbean of Latin America. In this work, salsa is investigated as a global phenomenon in the local context of Prague and at the same time as a commercialized product. In terms of salsa as a global phenomenon, the work deals with the characteristics of salsa as a social dance in the local context and tries to trace its social functions. In addition to the effects of the commercialization and tropicalized ideas of salsa and Latin American cultures on its form, the thesis also touches on topics such as internal negotiation and external construction of Latin American identity (latinidad), which are related to salsa as a global phenomenon and its commercialization. The work is based on several months of ethnographic research and semi- structured interviews conducted mainly with salseros from Latin America, the Czech Republic and others, not only European countries. Key words: salsa, social dance, global phenomenon, commercialization, product, commodification of culture, Latin American identity, latinidad , tropicalization, imagination
Children's books from the Baobab publishing house for pre-schoolchildren and their role in the development of the reading literary
Smutná, Petra ; Laufková, Veronika (advisor) ; Hník, Ondřej (referee)
The aim of this diploma thesis is to describe the uniqueness of the Baobab publishing house books for pre-school children and to find out what is the opinion of parents and pre- school teachers on selected books from this publishing house, on their content and on their graphic design. In the theoretical part I describe and explain the basic concepts of the reading literacy. I also devote to the contemporary situation in the book market for children, especially pre- school children, mostly non-readers. I focus on a small alternative publishing house called Baobab, its book production for children in general, and on its awarded books. In the empirical part I interviewed parents (41 returned questionnaires altogether) about their awareness and opinion on the Baobab publishing house and on selected books published by Baobab, namely Jak zvířataspí (How Animals Sleep), Šmalcova ABECEDA (Šmalec's Alphabet) and Z domu a zahrady (From the House And the Garden). I also interviewed 7 pre- school teachers to find out about their awareness of the Baobab publishing house and about their opinion on the selected books. Unlike the parents, all teachers had known the publishing house. It was proved that although the publishing house was awarded several prizes for its children's books (especially for the graphic design), the...
Water-use efficiency of winter wheat under heat and drought stress
Hlaváčová, Marcela ; Klem, Karel ; Novotná, Kateřina ; Rapantová, Barbora ; Urban, Otmar ; Hlavinka, Petr ; Smutná, P. ; Horáková, V. ; Škarpa, P. ; Trnka, Miroslav
Because such extreme weather events as dry spells and heat waves are expected to occur more frequently\ndue to climate change, the issue of appropriate water management for sustainable agricultural production\nis increasingly important. This study focuses on wheat, the second most widely grown cereal in the world\nand the most common cereal in European countries. The study assesses the effects of short periods (3 and\n7 days) of high temperatures (26°C as a control, 32°C, 35°C, and 38°C as daily temperature maxima from\n12:00 to 14:00) and drought stress at different developmental stages (DC 31 – beginning of stem elongation,\nDC 61 – flowering, and DC 75 – early grain filling) on water-use efficiency (WUE) in winter wheat\ncultivar Tobak. This cultivar is one of the most widespread winter wheat cultivars in Czech Republic fields.\nThe analysis of WUE showed that the cv. Tobak plants were able to withstand drought stress conditions\nthrough increased WUE. In contrast, wheat plants were stressed more markedly if exposed to higher temperatures\nand drought in combination. Generally, the wheat plants were most sensitive to drought at DC\n31.
