Notes: 1A, 5A (non-inoculated control plants with 1 mM or 5 mM NH4+, respectively); 1N, 5N (non-inoculated control plants with 1 mM or 5 mM NO3−, respectively); 1AI, 5AI (inoculated plants with 1 mM or 5 mM NH4+, respectively); and 1NI, 5NI (inoculated plants with 1 mM or 5 mM NO3−, respectively). The data are the means ± SD of four replicates. Significant differences (LSD test, p < 0.05) of the same parts of the plants among treatments are indicated by different letters.
