Fig. 1. Dry matter and total S accumulation and redistribution in soybean in Exp. 1. (A) Distribution of dry matter; (B) Distribution of total S. Both plots are cumulative, so that the area between the curves represents the plant organ; the top curve within each plot represents the total, whole-plant value. Soybean reproductive stages (R4.0–8.0) are along the bottom of the x axis. All values are means ± SE (n = 4).
