Stilbene concentrations in V. vinifera cv. Malvasia cell cultures subjected to different treatments and analyzed on day 6. Each value is the mean of 3 independent experiments ± S.D. Different letters indicate statistically significant differences (p ≤ 0.05) between samples. Comparison between the production under different treatments of: piceid (capital letters); resveratrol (lowercase letters); trans-ε-viniferin (underlined capital letters); trans-δ-viniferin (underlined lowercase letters); total stilbenes (Greek letters).
