Additional file 1 of Resveratrol improves the iron deficiency adaptation of Malus baccata seedlings by regulating iron absorption

Additional file 1: Figure S1 Effects of exogenous Res on apple seedlings under Fe deficiency stress in nutrient solution. (a) The phenotype resulting from the application of 100 µM exogenous Res to apple seedlings under Fe deficiency stress (The iron concentration was 4 µM, pH=5.9) at day 10. The apple seedlings in control group were cultured with complete nutrient solution (The iron concentration was 40 µM, pH=5.9). The etiolation rate (b) and fresh weight (c) of the apple seedlings after Fe deficiency and exogenous Res treatment for 10 days. Data represent the means ± SD of triplicate experiments. Different lowercase letters indicate significant differences, according to Fisher’s LSD (P < 0.05). Figure S2 Effects of exogenous Res on oxidative damage and antioxidant enzyme activities under Fe deficiency stress. Effects of exogenous Res application on the levels of O2·− and H2O2 (a) and MDA content (b) under Fe deficiency stress. Effects of exogenous Res application on the activities of SOD (c), POD (d) and CAT (e) under Fe deficiency stress. Data represent the means ± SD of triplicate experiments. Different lowercase letters indicate significant differences, according to Fisher’s LSD (P < 0.05). Table S1 The primers used for qRT-PCR.
