主　　题：Paris polyphylla var.yunnanensis arbuscular mycorrhizal fungi growth and development medicine quality 

摘      要：A field experiment was conducted to determine the effects of two commercial strains composed of mulple arbuscular mycorrhizal fungi(AMF)species on plant growth,antioxidant capacity,and medicine quality of Paris polyphylla var.yunnanensis in three subtropical soils from Wanzhou,Anshun and Baoshan in fields.The results showed that AMF inoculation enhanced the fungal colonization rate and activities of both succinate dehydrogenase and alkaline phosphatase,thereby,enhancing the mycorrhizal viability of P.polyphylla var.yunnanensis.The concentrations of photosynthetic pigments(chlorophyll a,b,a+b and carotenoids),soluble sugar,soluble protein and photosynthetic capacity were higher in AMF-inoculated plants than in non-AMF-treated plants in field.AMFtreated plants recorded higher activities of catalase,peroxidase and superoxide dismutase,and caused the reduction in malondialdehyde content,indicating lower oxidative damage,compared with non-AMF plants.Polyphyllin I,Polyphyllin II,Polyphyllin III,Polyphyllin IV and total polyphyllin contents were increased by AMF treatment.In conclusion,AMF improved the plant growth,antioxidant capacity and medicinal quality of P.polyphylla var.yunnanensis seedlings.Hereinto,AMF effects on the soil from Wanzhou was relatively greater than on other soils.
