Mycorrhizal syntheses of pine seedlings were conducted with the strain of Suillus luteus No 14 characterized by high tolerance to Al 3+ ions. The experiment was performed as a semi-sterile culture in peat-perlite medium with Al 3+ ion concentration of 4.0 mM. Three mycorrhizal morphotypes were distinguished on the pine roots: single, dichotomously branched and coralloid. The coralloid mycorrhizas were rare on plants treated with Al. Mycorrhizal plants. However mycorrhizas from seedlings treated with Al revealed a thinner mantle and a lack of the Hartig net as compared with the untreated control. There was no growth reduction of tested seedlings by the Al 3+ concentration used. Mycorrhiza formation with the selected S. luteus strain caused lower Al 3+ translocation to the upper part of the tested seedlings compared with the nonmycorrhizal control. It may be concluded that Al 3+ ion concentrations that appear in the moderately polluted fine-root layers of forest soil may in certain condition negatively influence mycorrhiza formation of young Scots pine trees.
