Vanadium concentrations in several plant species vary with their
leaf-stalk ratio. Leaves store high vanadium amounts. Seeds and
fruits prove to be particularly poor in vanadium (Table 5).

Bulges of roots (carrots), stems (kohlrabi) and tubes (potatoes)
are poor in vanadium, with the exception of potato peel (Table 6).
