The effect of three levels of fertilizer on the growth of three species of containerized-grown conifer seedlings (Pinus contorta, Picea glauca, and Picea mariana) and two species of bare-root conifer seedlings (Pinus sylvestris and Larix sibirica), and on the colonization of these seedlings by six species of ectomycorrhizal fungi (Hebeloma longicaudum, Laccaria bicolor, Paxillus involutus, Pisolithus tinctorius, Rhizopogon vinicolor and Suillus tomentosus), was studied. The growth of the seedlings in both container-grown and bare-root nurseries increased as the levels of fertilizer increased. For better seedling growth and environmental quality it may be possible to reduce the level of fertilizers in commercial nurseries up to 33% by using selected mycorrhizal fungi. Ectomycorrhizal colonization in all seedlings was not affected by fertilizer levels. Hebeloma longicaudum, L. bicolor, P. involutus, and P. tinctorius formed well-developed ectomycorrhizae, whereas ectomycorrhizal development by R. vinicolor and S. tomentosus was poor. Native mycorrhizal fungi colonized non-inoculated control seedlings; however, their colonization was always lower than with inoculated fungi.
