The present paper focus on aspects of tuning ectomycorrhizal inoculum in two cultivation systems for large-scale applications during nursery production of coniferous trees in target conditions. In both cases, a certain combination of fungal isolates resulted in improvement of some growth parameters of trees in target conditions.
The results indicate that appropriate inoculum product tuning by selection of efficient EcM fungal species or their combinations during field trials should be performed before large-scale applications.
