The uptake of bromacil, dichlorobenzonitrile (DCBN), nitrobenzene (NB) and dinitrobenzene (DNB) was studied in isolated barley roots and mature soybean plants. The uptake rate constants for soybean plants were in the order of DCBN = bromacil < NB < DNB. The same pattern was evident for the root tissue test, except for DNB. Metabolism of the (14)C-labeled chemicals indicated that DCBN was metabolized in the leaves but not in the roots. DNB was metabolized in the roots, and bromacil remained primarily as parent compound. A method for obtaining uptake rate constants is described.
