The Autoradiographic Detection of Ions in Plant Tissues1

Abstract

The autoradiographic techniques for the examination of the subcellular localization of ions in plant cells have been assessed. It has been shown that the use of a controlled-temperature freezing-sectioning technique, together with low-temperature, stripping-film autoradiography, may provide a more suitable method than is at present available for studies on ion uptake and movement in plant cells.
