Fig. 3.

Cross-sections of Cabernet Sauvignon rachises stained with FDA and examined for cell viability (green fluorescence) by confocal microscopy. A healthy cluster (A) and a cluster with symptoms of berry shrivel (B). Photos on the left in A and B show the appearance of the rachis without lateral branches (top) and of the whole cluster (bottom). Arrows in (B) indicate typical necrotic lesions similar to those analysed for Fig. 7. Micrographs on the right in A and B labelled 1–4 show cross-sections corresponding to positions 1–4 on the rachis; e, epidermis; c, cortex; p, phloem; r, ray; x, xylem; pi, pith. Fruit characteristics for key sections are: (A2) 24.9 °Brix, 1.0 g berry weight, 257 mg of solutes per berry; (A4) 25.0 °Brix, 1.0 g berry weight, 250 mg of solutes per berry; (B2) 11.9 °Brix, 0.63 g berry weight, 74 mg of solutes per berry; (B4) 15.3 °Brix, 0.47 g berry weight, 71 mg of solutes per berry.
