1 ABSTRACT Kateřina Muráriková Influencing of production of plant tissue culture of Trifolium pratense L. I The aim of this thesis was to check the influence of cinnamic acid, as a precursor of the phenylpropanoids biosynthesis, on the flavonoids production of Trifolium pratense L. suspension culture, to compare two varieties of this plant, the DO-8 one and the Tempus one, in terms of the effect of this precursor, and to help achieve the successful increase of the production of secondary metabolites by the Trifolium pratense L. explant cultures. Concerning the DO-8 variety, the changes of the isoflavonoids production as a result of the cinnamic acid influence have been also tested. The suspension cultures were being cultivated on the Gamborg's nutrient medium with the addition of 2 mg.l-1 2,4-dichlorphenoxyacetic acid and 2 mg.l-1 6-benzylaminopurine. The cultivation was being realised on a slow moving roller at temperature of 25 řC and in the period of 16 hours of light and 8 hours of dark. The cinnamic acid was added in the four concentrations and its influence was observed after 6, 24, 48 and 168 hours. The flavonoids determination was being applied on the check samples and the samples with the addition of cinnamic acid by the spectrophotometric method in agreement with the Český lékopis 2009 and the...
