Figure 2.
Leaf nutrient concentration of two genotypes (F160 and F7) grown under low-phosphorus conditions (LP) fertilized with either ammonium (AMM) or nitrate (NO3). Shoot phosphorus concentration (a), shoot nitrogen concentration (b), shoot potassium concentration (c), shoot manganese concentration (d), and shoot zinc concentration (e) [mg g−1] of four-week-old maize seedlings. Data represent mean values of five biological replicates ± SE. Different capital letters indicate significant differences at p < 0.05 according to Tukey’s HSD.
