Cross-sections of a Cabernet Sauvignon rachis with multiple symptoms stained with FDA and examined for cell viability (green fluorescence) by confocal microscopy. Micrographs on either side labelled 1–4 (a and b) show cross-sections corresponding to positions 1–4 (a and b) in the centre photo of the rachis with symptoms of bunch-stem necrosis (2a, 4), healthy berries (2b), and berry shrivel (3); e, epidermis; c, cortex; p, phloem; r, ray; x, xylem; pi, pith. Fruit characteristics for each section are: (2a) 12.6 °Brix, 0.61 g berry weight, 77 mg of solutes per berry; (2b) 27.3 °Brix, 1.0 g berry weight, 285 mg of solutes per berry; (3) 11.7 °Brix, 0.62 g per berry, 72 mg of solutes per berry; (4) 13.3 °Brix, 0.43 g berry weight, 56 mg of solutes per berry.
