Burgundy truffle Tuber aestivum Vittad. syn. T. uncinatum Chatin can be a profitable agroforestry crop outside the Mediterranean region. Truffle fungi grow symbiotically as ectomycorrhizae on the roots of host trees, notably hazels and oaks. In some parts of Poland, conditions appear favourable for cultivation of Burgundy truffle, but how management practices affect truffle establishment and fruiting remains to be studied. In a greenhouse study, we tested two inoculation techniques that differed in the method and timing of inoculum application on mycorrhizal colonization of Pinus sylvestris L., Larix decidua Mill., Quercus robur L., and Fagus sylvatica L. We found that the method of T. aestivum spore application under greenhouse conditions had no significant effect on mycorrhization efficiency, regardless of host plant species. Mycorrhization of larch, pine, beech, and oak seedlings by T. aestivum did not differ in time to infection or degree of mycorrhizal root infection. However, oak seedlings had a higher degree of mycorrhization, which explains the popularity of this species in truffle plantations.
