Responses of physiological parameters of native plant community to the allelopathy and its interactions with AMF (n = 10). The boxes represent the range of maximum and minimum values, with a bold horizontal line indicating the average value. Colors indicate different AMF treatments (orange, AMF; purple, NoAMF). The physiological parameters include leaf nitrogen (LN) (A) total chlorophyll concentration (Chl) (B) Fv/Fm (C) and specific leaf area (SLA) (D). There were five different concentrations of the root aqueous extracts of Rhus typhina including 0 g L− 1 (CK), 10 g L− 1 (LRE), 20 g L− 1 (NRE), 30 g L− 1 (MRE), and 40 g L– 1 (HRE). The different letters indicate a significant difference (p ≤ 0.05) with Duncan’s test.
