Table 3.

Tukey’s honest significance test for stilbenes (trans-resveratrol, trans-ε-viniferin and r2-viniferin) in µg/g d.w. for different particle sizes of grape cane. (Two-way ANOVA: ** p < 0.01, * p < 0.05, n.s. = not significant. Values are means and standard deviations calculated from three measurements).
