Limited impact of soil inocula from arbuscular and ectomycorrhizal-dominated sites on root morphology and growth of four tree seedling species from a temperate deciduous forest

Limited impact of soil inocula from arbuscular and ectomycorrhizal-dominated sites on root morphology and growth of four tree seedling species from a temperate deciduous forest

We inoculated seedlings of ectomycorrhizal (ECM) and arbuscular mycorrhizal (AM) tree species with soils from ECM-dominated forests or AM-dominated open fields ... However, only Acer grew better and invested less in autonomous root-based foraging, when inoculated with AM-dominated soils ... Both AM species (Acer rubrum L. and Ulmus americana L.) had higher AM colonization rates when inoculated with AM-dominated open field soils. However, only Acer grew better and invested less in autonomous root-based foraging, when inoculated with AM-dominated soils. Responses of ECM species to soil inocula were more nuanced. Both species remained unresponsive to inoculation treatment. Populus tremuloides Michx. ECM colonization was higher when inoculated with ECM-dominated soils, while neither root morphology nor mycorrhizal colonization responded to inoculum origin for Quercus rubra L.
