Abstract: Arbuscular mycorrhizas (AM) fungi is widely distributed excellent microbial resources in soil ecosystems and it is often used in medicinal plants with important economic value.In this study, Carthamus tinctorius was inoculated with different AM fungi: Glomus mosseae, Glomus intraradices and Mixed AM fungi (G.mosseae, G.etunicatum, G.microagregatum, G.caledonium, G.cladoideum and G.intraradices), respectively and inoculated with the same amount of inactivated bacteria as the control group.The inoculation effect of AM fungi was identified by measuring the infection rate and spore density, and the content of HSYA and kaempferol in C.tinctorius velvet was determined by high performance liquid chromatography at different picking stages.The purposes of this study were to investigate the effects of AM fungi on the growth and active constituents of C.tinctorius, and to analyze the effects of different flowering stages on HSYA and kaempferol so as to provide an important theoretical basis for promoting agricultural production of C.tinctorius in Xinjiang.We measured the content of hydroxysafflor yellow A and Kaempferol in C.tinctorius velvet by the high performance liquid chromatography method at different picking stages.The results showed that AM fungi could significantly promote the accumulation of aboveground parts, underground roots and floral biomass of C.tinctorius.In terms of the synthesis of secondary metabolites, there was no significant difference in the content of hydroxysafflor yellow A and Kaempferol in C.tinctorius under different AM fungi treatments and different growth stages.

Key words: arbuscular mycorrhizas fungi, mycorrhizal infection rate, soil spore density, secondary metabolite
