Abstract: Translocation and distribution of eight C-14-Iabeled amino acids were studied in two closely related barley varieties, Atlas and Atsel. The compounds were: L-valine; DL-valine; DL-lysine; L-histidine; DL-phenylalanine; DL-tryptophan; DL-arginine; and glycine. For purposes of comparison, similar experiments were also conducted with labeled amitrole, 2,4-D, and monuron. Labeled compounds were applied either to leaves or roots of eight-day-old plants. For leaf experiments, 0.1 ?mole at 10-2 M was applied; for root studies, 0.1 ?mole at 1-6 M in 100 ml of nutrient solution. Autoradiographs were made after one, four, and 14 days.
