Abstract

Stronger negative impact of salinity (100 mM NaCl for 4 days) on radish plants in comparison with tobacco ones, correlated with more profound decrease of bioactive cytokinins and higher elevation of activity of the main cytokinin degrading enzyme cytokinin oxidase/dehydrogenase and abscisic acid in the former species.
