Synopsis Substantial concentrations of carbohydrates were evident in roots of Du Puits, Vernal, and African seedlings 6 weeks after seeding. Neither growth under reduced light intensity nor 3 potash fertilization rates affected root concentrations of total available carbohydrates (TAC), but total amounts increased as root growth was greater under the higher light intensities and higher potash rates. Varieties differed less in the amounts of TAC produced than in the concentration of TAC in the roots.
