Different lowercase letters (a, b, c) in each column indicate significant differences compared with: (a) environments; (b) Cd rates; and (c) maize cultivars according to Tukey’s test (p < 0.05). Different uppercase letters (A, B, C) between columns indicate significant differences between structures of the same plant for each: (a) environment; (b) Cd rate; and (c) maize cultivar according to Tukey’s test (p < 0.05).
