| Outline of Final Research Achievements |
Low-yielding sweet potato rootstock plant grafted to the main stem with a scion from different sweet potato plant sometime significantly increase the growth compared to a graft between the rootstock plant. One of the reason why the partially grafted plant increased biomass production would have been that biologically fixed nitrogen was increased by endophytic bacteria (Enterobacter) living in the scion. It however seemed that the other factor such as auxin produced by microorganism could affect promoting the growth over than 50mg/L medium nitrogen concentration conditions.
