title: [Effects of AM fungi on growth and microelement of Scuteliaria baiealensis under different applied phosphorous levels].
abstract: The effects of AM fungi on the growth, nutrient uptake and microelement of Scutellaria baicalensis under different applied phosphorous levels in the pot culture were studied. The results showed that applied phosphorous levels had remarkable effect on AM fungal inoculation. Inoculation effect of AM fungi was the best under 0.12-0.18 g x kg(-1) soil. At those levels, the effect of AM fungi on the growth of S. baicalensis was the best, but either lower or higher phosphorous level showed suppressed infecting of AM fungi to S. baicalensis. After inoculation, the contents of biomass, total P, baicalin, total N of root were increased as well as the microelements of K, Ca, Mg, Fe, Zn, but the contents of total N of shoot, N/P were decreased as well as the microelements of Mn, Cu. In conclusion, the growth of host plant and using rate of phosphorus fertilizer can be promoted by inoculation of AM fungi.
