Cesium—134 distribution in native Andropogon scoparius clones and in single tillers indicates that each clone consists of a group of tillers each acting as individual plants. Two zones of concentration occur: the upper 5 cm of the roots and the inflorescence, including the florets. Cesium transport from the foliage to the upper portion of the roots occurs with fall dormancy. With the initiation of spring growth the mineral is exported from the roots to the expanding leaf blades. Cesium activity within the plants growing on the Heiden—Hunt clay soil decreases more with time than in plants growing on Tabor fine sandy loam. |
