FIGURE 6

Phenylalanine ammonia lyase (PAL) activity (A), peroxidase (POD) activity (B), and total phenolics concentration (C) of wounded and unwounded (control) roots during 28 days storage at 6 and 12°C. Roots were wounded by abrading the root surface with a wire brush 2 h after harvest and were subsequently stored at 94% relative humidity. PAL and POD activity are expressed as μmol product min-1 (g protein)-1. Total phenolics are expressed as μmol gallic acid equivalents (g dry wt)-1. Data are the mean ± SE of the mean of five replicate roots.
