Fig. 7.

Correlation between the extent of rachis necrosis and the severity of berry shrivel (A), and necrotic lesions in a rachis axil or on a pedicel (B). Each data point represents a single cluster (n ≥62). Data for two cultivars (Cabernet Sauvignon and Semillon) and five vineyard locations were pooled. Curves were fitted by negative exponential smoothing. Correlations were also significant within cultivars and within vineyard locations; differences between years were not significant. Note that lenticels in B are raised, whereas necrotic lesions are depressed.
