Effect of Fe deficiency and NaHS treatment on the contents of abscisic acid (ABA) (a), zeatin (ZA) (b), gibberellin (GA) (c), indoleacetic acid (IAA) (d), free salicylic acid (SA) (e), bound salicylic acid (SA) (f), and jasmonic acid (JA) (g) in leaves and roots of Glycine max plants. The 3-w-old G. max seedlings were treated with the nutrition solution containing 1 μM Fe(III)-EDTA or 50 μM Fe(III)-EDTA with or without 100 μM NaHS for 15 d. Error bars represents the mean ± SE. Columns labelled with different letters indicate significant differences at P < 0.05. –Fe, 1 μM Fe; −Fe + NaHS, seedlings treated with 100 μM NaHS and 1 μM Fe; +Fe, 50 μM Fe; +Fe + NaHS, seedlings treated with 100 μM NaHS and 50 μM Fe
