The results suggested that Aster amellus is an obligate mycotrophic plant species with a high dependency upon mycorrhiza. Plant biomass was affected only by soil, and not by population or the interaction between the population and the soil. Mycorrhizal colonization was significantly affected by all three factors (soil, population, interaction of soil and population). Plants from the population originating from the soil with lower nutrient availability developed more mycorrhiza even when grown in soil with higher nutrient availability. The correspondence between mycorrhizal colonization of plants in the field and in both soils in the pot experiment suggests that the observed differences in root colonization have a genetic basis.

Aster amellus je obligátně mykorhizní druh. Biomasa byla ovlivněna půdou, ale ne populací či inetrakcí mezi houbou a populací. Mykorhizní kolonizace byla ovlivněna všemi třemi faktory. Rostliny z populace z lokality s nízkým obsahem živin vytvářeli vyšší kolonizaci i když byly pěstovány v půdě s vysokým obsahem živin. Shoda mezi kolonizací rostlin v terénu a v experimentu ukazuje, že pozorované rozdíly v mykorhizní kolonizaci jsou podmíněny geneticky.
