Some enzyme changes in chicory (Cichorium intybus) during forcing

Differences in beet weight and sugar concentration of four commercial varieties grown on two types of soil and at different planting density were related to changes in the numbers, sizes and sugar storage capacities of the storage root cells. Much of the variation in beet weight between varieties and soil type was attributable to differences in cell size, less to differences in their number. Differences in weight of beet grown at different densities were caused equally by changes in number of cells and their size. Variation in sugar concentration of the beet was, in all cases, determined more by differences in cell size than in their capacity tostore sugar, but the two factors were not wholly independent of each other.
