a Comparative analysis of CAT, POD, PAL, and SOD activities and TPC in genotypes at 20 days post inoculation (dpi) at transplanting stage. U = 1 mmol of hydrogen peroxide∙min 1 of protein decreased by CAT, 1 mmol of tetraguaiacol or 1 μmol of trans-cinnamic per minute released by POD or PAL activities, respectively, and amount of enzyme required to inhibi b 50% of the NBT photoreduction∙min. Each value represents the mean of 3 replicates. Different letters indicate statistically significant differences (P ≤ 0.05). b Control, non-inoculated tomato genotypes, c Treatment, inoculated tomato genotypes.
