Potassium concentrations in microgreens treated with ascorbic acid and KOH buffer in (A) Experiment 1—greenhouse conditions, (B) Experiment 2—greenhouse conditions, and (C) Experiment 3—laboratory conditions. Significant differences (p ≤ 0.05) among treatments are indicated by different lowercase letters within the experiment. (n = 5). Bars represent ± 1 standard error of the mean. FW fresh weight.
