摘 要：The aim of this study was to analyze the performance of Acaena elongata colonized by arbuscular mycorrhizal fungi(AMF)to different phosphorus(P)concentrations,as a measure of AMF ***,is a species from soils where P availability is limited,such as temperate *** research questions were:1)How do different P concentrations affect the AMF association in Acaena elongata,and 2)How does the AMF association influence ***’s growth under different P concentrations?***’s growth,P content in plant tissue,AMF colonization and dependency were measured under four P concentrations:control(0 g P kg^(-1)),low(0.05 g P kg^(-1)),intermediate(0.2 g P kg^(-1))and high(2 g P kg^(-1))in different harvests.A complete randomized block design was ***’s growth was higher under-AMF in intermediate and high P concentrations,and the lowest growth corresponded to+AMF in the low and intermediate P *** observed a negative effect on the root biomass under+AMF in intermediate P concentration,while the P concentration had a positive effect on the leaf area *** AMF colonization in *** decreased in the highest P concentration and it was favored under intermediate P concentration;while the low and the high concentrations generated a cost-benefit *** results suggest that the performance of some plant species in soils with low P availability may not be favored by their association with AMF,but a synergy between AMF and intermediate P concentrations might drive ***’s growth.
