The authors regret that Fig. 9 relating sucrose weight to total dry weight contained a few misplotted measurements. The sixth group of bivariate observations (five data points) were plotted a factor of 10 g/plant too light in the y-direction (sucrose weight). This error was not present in curve fitting, thus the fitted relationship (Fig. 9; Table 2) is correct fitted relationships on Figs 5 and 9 and thus also remain unchanged. Figure 9 should be presented as
