Morphological characteristics and metal profiling of plants grown under conditions of Fe deficiency and excess. a) Root length (cm). b) Shoot length (cm). c) Chlorophyll content. d) Shoot Fe. e) Shoot Zn. f) Shoot Mn. g) Shoot Cu. h) Root Fe. i) Root Zn. j) Root Mn. k) Root Cu (μg/g dry weight). Vertical bars followed by different letters are significantly different from each other, according to the Tukey-Kramer test (p < 0.05; n = 4).
