Inorganic phosphate (Pi) content in leaves of L. japonicus seedlings inoculated with R. irregularis and repeatedly irrigated with PAW 5’, PAW 10’ or H2O. Pots containing L. japonicus seedlings were irrigated twice per week alternating low phosphate modified Long-Ashton with either PAW 5’ (blue), PAW 10’ (violet) or H2O (control, green) and harvested after 4 (A, early phase), 5 (B, mid phase) or 7 weeks (C, late phase) after the first treatment, respectively. PAW was obtained by exposing deionized H2O for either 5–10 min to atmospheric plasma generated by a plasma torch operating at 900 W. Data are the means ± SE of 5 biological replicates. Bars labelled with different letters differ significantly (p < 0.05, ANOVA test followed by Tukey’s HSD)
