Notes	Sucrose solution, as an artificial photosynthetic-source, was injected into two sweet potato cultivars, Koganesengan (KOG, an early production type） and Minamiyutaka （MYK, a late production type), to investigate the cultivaral difference in the sucrose injection effect on root growth and the activity of ADP-glucose pyrophosphorylase （AGPase） in tuberous roots. The sucrose injection applied on the 35th day after rooting was highestly effective in increasing the productivity and AGPase activity of tuberous roots in KOG. This time corresponded to the growth stage at which the ratio of dry matter distribution to stems began to drop. By this treatment, the tuberous root of KOG doubled in weight and the activity of AGPase was 25% higher compared to those of the. control plant. This may suggest that the formation and production of tuberous roots in KOG are possible to be promoted by temporarily enhancing the source potential at the adequate growth stage. However, in MYK a clear changing point was not detected in the dry matter distribution ratio during the experiment period and the effect of sucrose solution injection was almost negligible.
