%X In this paper, a pot experiment with three compartments was installed to study the effect of Na-phytate on the development and metabolic activity of AM fungi. Maize was selected as host plant and inoculated with arbuscular mycorrhizal fungus (Glomus intraradices), and different amounts of Na-phytate were applied into hyphal compartments. The results showed that the absorbed P in the shoots and roots of maize inoculated with AM fungi was 1-2 times higher than that of non-inoculated maize. The ALP activity in intraradical hyphae of AM fungi was significantly decreased, and the total hyphal density of AM fungi increased with applied Na-phytate. Observations suggested that the ALP activity in intraradical hyphae of AM fungi and the development of its extraradical hyphae could be regulated by Na-phytate. Additionally, AM fungi could enhance the plant's P absorption and utilization from native soil P and additive Na-phytate.
