Effect of heat-girdling on 52Fe translocation from the roots to the shoots in Fe-deficient barley (Experiment 1). (A and C) Gross images of steam-treated (A) and untreated (C) barley. (B and D) Images of the distribution of 52Fe in steam-treated (B) and untreated (D) barley detected by a BAS-1500. Arrowheads indicate the position of steam treatment. Leaf numbering: 4, youngest leaf (YL); 3, third leaf; 2, second leaf; 1-2, youngest leaf of the first tiller; 1-1, first leaf. Scale bar = 4 cm. (E) The ratio of the 52Fe radioactivity of the upper region to that of the lower region after heat-girdling the third and fourth youngest leaves (YL).
