Transfer of Cesium from the Xylem to the Phloem in the Stem of Wheat

By Urs Feller, T. Riesen and H.-J. Zehnder

Abstract

Steam-girdling experiments with detached wheat shoots showed that cesium was eliminated from the xylem sap and loaded into the phloem during acropetal transport. This transfer is important for the accumulation of cesium (especially also of the radiopollutants 134Cs and 137Cs) in maturing wheat grains
