Abstract The species and mycorrhizal structure type of arbuscular mycorrhiza fungi(AMF) in rhizosphere of new eight medicinal plants,and the effect of soil factors on colonization rate were studied.The results showed that 31 species of AMF were identified from the rhizosphere of new eight medicinal plants,in which G.melanosporum and G.mosseae were the dominant fungi.Mycorrhizal structure type of Radix trichosanthis,Aster tataricus and Adenophora stricta were Intermediate-type,Angelica dahurica,Schizonepeta tenuifolia and Rhizoma dioscoreae were Arum-type,while Dendranthema morifolium and Semen coicis were Paris-type,respectively.Path analysis indicated that protease activity played a leading role in their mycorrhizal fungal colonization rate.Conclusively,the new eight medicinal plants with AMF formed good symbiosis,and the soil factors affected the species distribution and infection status of AMF.
