Root and foliar uptake, translocation and distribution of [14C]fluoranthene in pea plants

0
Uptake of 14C‐labelled fluoranthene ([14C]FLT) via both roots and leaves of Pisum sativum seedlings and distribution of [14C] in plants by both acropetal and basipetal transport was evaluated. The highest [14C] level was found in root base (≈270 × 104 dpm/g dw) and the lowest level in the stem apex (<2 × 104 dpm/g dw) after just 2 hours of root exposure. For foliar uptake, the highest level of [14C] was found in stem and root apex (both ≈2 × 104 dpm/g dw) (except for treated leaves), while the lowest level was found in the root base (<0.6 × 104 dpm/g dw).
