Comparative analysis of localization of zeatin and its riboside was carried out with the help of modified method of cytokinin binding prior to dehydration of tissues, enabling differential detection of the presence of either free bases or their ribosides on tissue sections using antibodies to zeatin riboside. We showed intensive staining for both zeatin and its riboside weakening in the cortex region with the transfer of cells to extension growth. Peculiarity of immunohistochemical detection of zeatin riboside was in the presence of files of intensively labeled cells in the region of the central cylinder. Staining for zeatin was decreased sharply by inhibition of secondary active transmembrane transfer, while staining for riboside of zeatin changed insignificantly under the influence of protonophore.
