±Standard error of the mean (n = 3). Means followed by the same lowercase per column (translocation of 14C-imazamox within a time evaluated) or uppercase per double plant section row (translocation of 14C-imazamox between biotypes at different time intervals) does not differ by the Tukey test (P < 0.05).
