The plants were grown in substrate with native AMF community (AMF) or sterilized control substrate (Control), non-inoculated (NI), inoculated in-situ (in-situ) or pre-inoculated (pre) with R. irregularis ‘Chomutov’. D6 and D12 are directly inoculated donor plants harvested after six or 12 weeks of cultivation, respectively; N6 are six-week-old neighboring plants. Values are g of shoot dry biomass, means of 4–6 replicates (SD), for exact replicate numbers see S12 Table. F-values are given according to one-way ANOVA with substrate × inoculation combination as factor.
*** P < 0.001. Means within column significantly different at P < 0.05 according to Tukey's test are marked by different letters; n.d. not determined.
