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.

研究了丛枝菌根(AM)真菌根外菌丝的酸性磷酸酶(ACP)活性，以阐明AM真菌对土壤有机磷的利用。将AM真菌红根菌接种或未接种的葱幼苗在盆中生长。用 30 µm 孔径的尼龙网将其分为根室和菌丝室接种的A. fistulosum 菌丝室中土壤溶液的ACP 活性高于未接种的植物，在低土壤P 条件下，ACP 活性高于高土壤P 条件下的ACP 活性。克拉鲁斯 (R. clarus) 分泌 ACP，其活性在缺磷条件下被诱导。
