Komparace vybraných pěstebních substrátů při zakořeňování bylinných řízků okrasných rostlin a jejich následné výsadbě
Hrabík, Pavel
This thesis deals with the level of influence of used substrates, during propagation of shrubs by herbaceous cuttings, to quality of their rooting. Also was tested the impact of these substrates for subsequent growth after planting into loose soil. Thesis includes literary section which summarizes information about plant propagation including factors that affect it and informations about substrates. Part of this work is an experiment that is thoroughly described there, including the methodology and results. The first part of the experiment was conducted in two terms and each term contained four variants. Each variant is one of the tested substrates. In these substrates were grown two taxa: Cotoneaster dammeri Schneid. and Cotoneaster salicifolius Franch. Parkteppich. Total it was evaluated nearly 3,500 cuttings. Furthermore it was 400 plants were planted in loose soil and after overwintering were also evaluated their quality parameters. The result of the experiment is that the quality of the substrate has a really affect to the quality of the rooting of cuttings. A major impact on their subsequent growth has not been confirmed.

The role of small non-coding RNAs in the regulation of plant reproductive development
Hromadová, Michaela ; Honys, David (advisor) ; Rothová, Olga (referee)
Small RNAs (sRNA) are broadly defined as regulatory molecules of 21-24 nucleotides in length which belong to the class of noncoding RNAs. They usually originate in response to the presence of double-stranded RNA in the cells and facilitate transcriptional and posttranscriptional gene silencing of complementary sequences. Their role lies not only in defence against exogenous nucleic acids, but primarily in the regulation of endogenous genes. Typical target molecules of plant sRNA are transposable elements and genes encoding the transcription factors involved in the control of key developmental transitions like the initiation of the reproductive phase and the regulation of its progress. The aim of this thesis is a summary of functional roles of individual small RNA in plant reproductive development, with focus to the female and male gametophytes and in the protection against the transition of transposable elements to following generations. Both endogenous and exogenous sRNA are amply utilized in plants, because they provide an immediate and direct response of the organism to rapidly changing conditions, and thus undoubtedly belong to the key factors which contribute to their phenotypic plasticity.

Hendrych, J. ; Borský, J. ; Jech, D. ; Létal, A. ; Malá, E. ; Obdržálek, J. ; Vorel, I. ; Žlebčík, J.
Práce zahrnuje úvodní obecnou analytickou část, jejímž účelem je stručné informativní shrnutí současného poznání a komplexní podstaty řešené alejové problematiky. Na tuto část navazují konkrétní kapitoly v rámci odborné aplikované části: Mapování a dokumentace alejí (popisující stanovené a odzkoušené metody mapování, dokumentace a evidence sledovaných jevů a prvků významných alejových linií a stromořadí v krajině), Množení alejových dřevin (kde jsou rozebrány vhodné metody přemnožení vybraných alejových dřevin, péče o ně a jejich další pěstování) a Obnova a management historických alejí (kde jsou popsány jak současné postupy a principy péče a ochrany alejí a jejich dřevin, tak i používané metody (včetně zahraničních) revitalizací a obnov, které jsou významné z hlediska současné praxe).
