The results of the present study show that inoculation with the ectomycorrhizal fungus Pisolithus tinctorius (Pers.) Coker and Couch potentially enhances the germination of Scots pine (Pinus sylvestris L.) somatic embryos in vitro. Stimulation by Pisolithus tinctorius was only observed in the absence of direct contact between the symbionts; mature embryos were not sufficiently robust for balanced interaction with the fungus on half-strength DCR medium. Subsequently, on MMN medium with a reduced sugar concentration, direct contact between somatic embryo-derived plants and the fungus resulted in in vitro formation of mycorrhiza. Ex vitro inoculation also improved adaptation of the somatic embryo-derived plants, even though mycorrhizal structures were not observed. The reactions to Pisolithus tinctorius varied between different Scots pine cell lines both in vitro and ex vitro.
