5 AbstractAbstractAbstractAbstract It has been since 19th century when the phytohormones and their crosstalk became one of the central themes in plant biology. Due to advances in molecular biology there is number of metabolic pathways linked to certain groups of plant hormones revealed by now, nevertheless much remains to be determined about their cooperation. The aim of this thesis is to evaluate the effect of exogenous cytokinin application on oat leaf segments (Avena sativa) - both specifically towards other phytohormones levels and generally in physiological context (in relation to their senescence). Our results confirmed increased auxin levels due to exogenous application of selected cytokinins and identified biological activity of trans-zeatin-9-glucoside (previously considered as irreversibly deactivated cytokinin type substance) in respective plant model. (In Czech) Key words: phytohormones, auxin, cytokinin, Avena sativa, senescence assay
