In vitro interaction of the truffle Terfezia terfezioides with Robinia pseudoacacia and Helianthemum ovatum.

摘要: The type of thein vitro root interactions ofTerfezia terfezioides with the plantsRobinia pseudoacacia andHelianthemum ovatum was investigated including detailed anatomical and ultrastructural characterization. No difference in growth detected at different phosphate concentrations on agar synthetic medium between inoculated control plants during a short-time cultivation. fungal colonization roots increased higher level both plant species, but always lower inR. roots. Septate hyphae formed frequently intracellular branched coils dead cortical cells. InH. intercellular were observed forming finger-like structures reminiscent Hartig-net ectomycorrhizae. A loose hyphal envelope covered surface colonized noncolonized features resembled similar described earlier mycorrhizae differentTerfezia species. Our study shows that theT. cannot be considered unambiguously as mycorrhiza.
