Potato tuber tissue maceration ability and pectinolytic activity of the D. solani strains. (A) Maceration ability in grams of macerated tissue, 48 h post inoculation. (B) Total pectate lyase specific activity (μmol min−1 mg−1) in the presence of polygalacturonic acid. Means ± standard errors are depicted, n = 10 for (A) and n = 3 for (B). Within each panel mean values marked with different letters are significantly different by Kruskal–Wallis test followed by post hoc analysis using Fisher's least significant difference criterion (R agricolae package). All statistical hypotheses were tested at p < 0.05.
