Abstract
CALCIUM ions are known to be practically immobile in the phloem of plants and are thus not re-translocated from older leaves1. Other elements manifesting low phloem mobility are zinc, boron and iron; the last-mentioned is also immobilized in the xylem in various circumstances2. Apparently, it has not been suggested that elements other than iron may be immobilized in the xylem2.
