| Research Abstract |
Activity of acid phosphatase (ACP) from extraradical hyphae of arbuscular mycorrhizal (AM) fungi was studied in order to clarify utilization of soil organic phosphorus by AM fungi. Seedlings of Allium fistulosum were inoculated or uninoculated with AM fungi Rhizophagus clarus and were grown in pots that were separated into root and hyphal compartments with nylon net of 30 µm pore size. ACP activity of soil solution in hyphal compartment was higher in inoculated A. fistulosum than uninoculated plant. ACP activity in inoculated plant was higher at low soil P condition than that at high soil P condition. These results suggest that extraradical hyphae of AM fungi R. clarus exude ACP and its activity is induced under P deficient condition.
