Time course of PAL (a), POD (b), PPO (c), and CAT (d) activities in extracts from apple calli inoculated with PDA (control), LXS080601, LXS081501, and LXS081501 + LXS080601. Data represent the mean of “Fuji” and “Gala” cultivars in two independent experiments. Error bars represent standard error of the mean.
