Abstract


Cytokinin activity was determined in roots, crowns, ears of six varieties of the barley in the tobacco Wisconsin 38 callus tissue test. Analysis was made in early stage of ears. The order increasing values of the total cytokinin activity (the total activity of compounds fitting their mobility with zeatin, zeatin ribosid and their more polar derivatives) were for most part of varieties: younger roots < older roots < crowns < ears. Dependences between the cytokinin activity and fresh weight of analysed material were not found.
