Knautia arvensis plants originating from two serpentine and two non-serpentine populations were grown in their native substrates and inoculated with one of the four serpentine isolates of arbuscular mycorrhizal (AM) fungi or with a respective complex native AM fungal community. Inoculation significantly improved the performance of all the K. arvensis populations. The extent of mycorrhizal growth promotion was mainly governed by nutritional status of the substrate, while the effect of AM fungal identity was negligible. Inoculation with the native AM fungal communities was not more efficient than inoculation with single AM fungal isolates in any plant population. Regardless of AM symbiosis, K. arvensis populations significantly differed in their relative nutrient accumulation ratios, showing the plant’s ability to adapt to nutrient deficiency/excess.
