Ureide concentration in uppermost expanded trifoliolate leaf and relative ARA in response to Mn fertility and soil water treatment for Jackson and KS4895, Experiment 2. Values of ARA are expressed relative to the well-watered control for a given day. FTSW for water-deficit treatment at measurement on days 2 and 3 and for first measurement on day 4 were 0.24, 0.15, and 0.08, respectively, and was 0.6 for all other measurements. FTSW was 0.6 for all measurements in the well-watered (WW) treatment. Bars represent the average se for a treatment on a given day.
