Figure 6

Temporal variation of quantified % CC; (a) Pinot gris; (b) Riesling; and (c) Cabernet Franc. The line represents the nonlinear regression model with an asymptote. The red line represents the time when it reaches the asymptote. Cabernet Franc (c) did not reach an asymptote. The x-axis represents the number of weeks after berry set (E-L stage 27).
