Description:	A pot experiment was conducted to examine the significance of indigenous arbuscular mycrorrhizal fungi (AMF) for growth and phosphorus upatake in some important introduced forage grasses at different soil pH levels in a Brazilian Oxisol. Plants of Brachiaria brizantha (BB), B decumbens (BD), B.humidicola (HU) and panicum maximum (PM) were grown in a glasshouse for 70 days with or inoculation with indigenous AMF at 3 levels of initial soi pH (4, 3, 5.1 and 6,4) After the growth period. dry weight, concentration of phosphorus (P) and P uptake were determined in both shoots and roots. Inoculation with AMF increased both shoot and root dry weighs in BD, BB and PM, but not in HU. Shoot and root P concentrations and total P uptake per pot in all species were improved y mycorrhizal inoculation. Plant growth and P uptade were directly related to soil pH in al grass speceis. All grass species showed the highese mycrorrhizal dependency for dry matter producrtion and P uptake at the lowest soil pH level.
