Genetic variation in the stilbene response to UV-C. The accumulation of different stilbene species was determined for 86 genotypes of V. sylvestris and a few cultivars. Values are represented in the boxplot format, whereby the box comprises the data for the central 50% of the sample, the horizontal solid line represents the median value, and the dotted line gives the position of the maximal and minimal values excluding the outliers; the outliers are indicated as individual points and were defined as those values that were >1.5 times the upper or lower quartile, respectively. (A) Pooled cis- and trans-piceid; (B) pooled cis- and trans-resveratrol; (C) viniferin; (D) pterostilbene; (E) pooled cis- and trans-piceatannol.
