Abstract Paris polyphylla var. yunnanensis is a traditional Chinese medicinal plant, in which polyphyllin as the main medicinal component is an important secondary metabolite with bioactivity. Arbuscular mycorrhizal fungi (AMF) have multiple positive effects on plants, while it is not clear whether AMF increase the content of medicinal components in medicinal plants. In this study, a total of nine AMF treatments were laid to analyze the mycorrhizal effect on polyphyllin accumulation and PpHMGR and PpSE expression of P. polyphylla var. yunnanensis. AMF increased the content of polyphyllin in the cultivated variety with low relation to the increase of inoculation intensity. Polyphyllin… More >

Abstract 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… More >
