Figure 4

Fe content (μg) measured by ICP-OES in 14-day-old roots (A), stems (B), unifoliate (Uni) (C), and trifoliate (Tri) leaves (D) of “Fe-efficient” (EF, PI 360952) and “Fe-inefficient” (INF, PI 407707) accessions and grown at 60% and 90% relative humidity (RH) under Fe-sufficient (SUF) and Fe-deficient (DEF) conditions. Data are means ± SEM. Different letters indicate significant differences (P < 0.05) between treatments. Statistical analysis was performed independently for each accession.
