Fig. 1. Accumulation of Chi1b, CH3, GLUC, PAL, and STS transcripts in bunchstems and flowers/berries of control and UV-C-treated inflorescences/clusters from separated floral buds stage (BBCH 57) to groat-sized berries stage (BBCH 73), 24 h after treatment. Numbers above the UV-C-treated bars represent induction factors compared with controls defined as 1× expression level. Results are means of duplicate data of one representative experiment out of two.

Fig. 2. Chitinase activity in bunchstems or flowers/berries of control and UV-C-treated inflorescences/clusters from separated floral buds stage (BBCH 57) to groat-sized berries stage (BBCH 73), 96 h after treatment. Data are means of eight samples of one representative experiment out of two. At each BBCH stage, means with the same letter were not significantly different (P <0.05).

Fig. 3. Inflorescence (A, B) (BBCH 68) and cluster (C, D) (BBCH 73) observed under UV-light (365 nm) 24 h after UV-C irradiation at 254 nm for 6 min (scale bar=1.3 cm). Controls consisted of non-irradiated inflorescences (a) or clusters (c). A bright blue fluorescence characteristic of stilbenes was observed in bunchstems (B, D) and berries (D) after UV-C treatment. Sixteen irradiated and non-irradiated plants were observed.
