ECTOMYCORRHIZAL FORMATION IN SEEDLINGS OF QUERCUS LIAOTUNGENSIS
辽东栎幼苗的外生菌根合成

Ectomycorrhizal formations on the roots of Quercus liaotungensis were studied on seedlings germinated and grown in pots in a greenhouse environment. Ectomycorrhizal fungi observed were Gomphidius viscidus, Russula foetens, Suillus grevillei, S. luteus, Pisolithus tinctorius, Boletus edulis, Cortinarius russus and Cenococcum geophilum. Ectomycorrhizal formations were observed on seedlings inoculated by G. viscidus, R. foetens, S. grevillei, S. luteus, P. tinctorius, B. edulis, but not on those inoculated by C. russus and C. geophilum after two months. In ectomycorrhizal tissue sections, clear Hartig nets were observed in the intercellular space of cortical cells of fine roots, effectively demonstrating the symbiotic relationship between each these 6 species of ectomycorrhizal fungi and seedlings of Q. liaotungensis.
