Data were recorded in plants derived or not from T. harzianum T34-treated seeds, and with or without two applications of salt stress (2 l of a 300 mM NaCl solution per 10 plants). NPK fertilizer was applied to 24-day-old plants, and salt was applied to 32- and 36-day old plants. All measurements were taken on 39-day-old plants. Height (cm), diameter (mm), fresh weight (g), canopy dry weight (g), and root dry weight (g). Each value is the mean of 10 biological replicates per condition (n = 10). Significant effects were determined by a two-way ANOVA (^∗P < 0.05, ^∗∗P < 0.01, ^∗∗∗P < 0.001) for T34, salt and the T34 × salt interaction, ns, no statistical differences. Different letters denote statistical significance for the T34 × salt interaction.
