Figure 7. Impacts of Grapevine redleaf disease (GRD) on yield and berry quality parameters for Merlot grapevines.

Figure 7

Impacts of the disease on (A) shoot length, (B) fruit yield, (C) number of clusters, (D) pruning weight, (E) leaf carbohydrates, and (F) total soluble solids, (G) anthocyanins, (H) titratable acidity and (I) pH of berries from symptomatic (red color columns) and non-symptomatic (green color columns) grapevines. Columns represent mean value and vertical bars indicate standard errors. Significant differences between symptomatic and non-symptomatic grapevines was determined by one-way ANOVA using the SigmaPlot 11 software and indicated by asterisks (* = p≤0.05 and ** = p≤0.001).
