The size distribution of cell aggregates, and the effect of cell aggregate size on anthocyanin content of Daucus carota cells in suspension cultures, was studied. The profile of biomass distribution in various size groups of cell aggregates indicated that over 92% of biomass was present in the aggregates of 500-1500 micromoles in diameter. The anthocyanin content increased initially with the increase in cell aggregate diameter up to 500-850 micromoles, and decreased rapidly with the increase in the cell aggregate size above this critical diameter. On the other hand, the surface colour intensity showed a steady increase with the increase in cell aggregate size, indicating a steep radial gradient of anthocyanin content along the radius of the larger cell aggregates.
