Table 3. The concentration of individual free amino acids [μmol per g fresh weight] in tomato plants at 21 days post inoculation with Verticillium dahliae (+Vd).
Values presented as the mean ± SD (n = 2), each replicate consisting of five plants, and analysed as two technical replicates. Asterisks indicate statistically significant differences (p < 0.05) between non-inoculated and inoculated plants.
