Studies have been in progress to determine the distribution of sucrose within the beet in order to assess the efficiency of sucrose accumulation in various parts of the beet and to help to estimate the potential for accumulation. Typical data are illustrated in Table 1 and Table 2. Sucrose concentrations are lower in the interzonal parenchyma (the tissue between the vascular rings) than in the tissues of the vascular ring, particularly in the interior regions of the beet. Generally, the lower the average sucrose concentration in the beet, the greater the difference between ring and interzone. In low sucrose beets (Table 2 and Table 3) the differences between the sucrose concentration of the vascular ring and the center of the interzone can be very large. This effect probably occurs because much of the sucrose reaching the roots is used in growth rather than being stored and the sucrose is preferentially stored in the tissue of the vascular ring.
