Abstract: | A greenhouse experiment was carried out to determine the growth, micronutrient content and vesicular-arbuscular mycorrhizal
(VAM) colonization of fescue and clover plants growing on a composite lignite mine soil. Five VAM fungus inocula were used.
Results show that mine spoils had a high potential acidity and poor physical and chemical conditions for plant growth. Toxic
levels of Al, Mn and Zn were found in plant tissues, with fescue showing apical necrosis. Glomus deserticola was the only VAM fungus that succeeded in colonizing plant roots, although it failed to improve the establishment or development
of either species. |
