Abstract: In this paper, four species of the genus Pedicularis L.,P.tricolor Hand.-Mazz.var.tricolor, P.siphonantha Don var.siphonantha,P.integrifolia Hk.f.subsp.integerrima Tsoong P.ditrotoma Bonati effected by mycorrhizal fungi were studied. Hyphae of mycorrhizal fungi invaded into root cortex and intracellular vesicles formed vesculas in all host species.On the top of some hyphae in soil, chlamydospores were formed. According to the characters of these spores, all fungi from four species of Pedicularis were identified as Glomus mosseaeNicol.& Gerd. Cultivationure experiments of P.tricolor and P.ditrotoma implied that myorrhizal fungi could increase nutrient absorption of host plants, and have promoted nutrient utilization.

Key words: Pedicularis
