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.

Keywords: grains; maturation; radioisotopes; transport; Triticum aestivum
Subjects: cesium transfer, xylem, phloem; maturation, seed, cesium; seed maturation, cesium; Triticum aestivum; wheat, cesium treansfer; xylem to phloem transfer, cesium
