Fig. 4. ³⁵S accumulation and redistribution in soybean plants pulsed at 65 and 98 d after imbibition in Exp. 2. Distribution of ³⁵S components in plants pulsed at 65 DAI (A, C, and E), and in plants pulsed at 98 DAI (B, D, and F). All plots are cumulative, so that the area between the curves represents the plant organ; the top curve within each plot represents the total. Soybean vegetative stages (R4.0–8.0) are along the bottom of the x axis. All values are means ± SE (n = 4).
