The ability of each species to tran

The ability of each species to translocate heavy metals and B from
the roots to the shoots was calculated by the following translocation
index (TI) as previously described by Abichequer and Bohnen (1998):
TI (%)=QPA (mg pot−1) /QAP (mg pot−1)×100, where QPA is the element
accumulation in the shoots and QAP is the element accumulation
in the whole plant (shoots and roots).
