The effect of amendments on Lolium perenne roots arbuscular mycorrhizal fungi colonization when cultivated in contaminated soil

Abstract Arbuscular Mycorrhizal Fungi that colonize the roots of plants growing on lands contaminated by heavy metals may influence phytostabilization process reducing translocation to aboveground parts plant. This study aimed evaluate effects soil amendments (lime and lignite) concentration bioavailable form (CaCl 2 extraction) in colonization Lolium perenne when cultivated soil. During experiment, bioavailability Pb, Cd, Zn was significantly reduced after application amendments, causing an increase L. shoot dry biomass. It observed higher dose lime (0.5%) resulting amplified values relative mycorrhizal intensity. However, independently dose, treatments increased occurrence arbuscules roots, with highest value 0.25% 5% lignite. The results for first time present effect lignite indicating arbuscules. These findings suggest order explain different responses applied treatment further investigations are needed identify spore morphology. experiment were implemented stabilize during remediation a spoil heap Ruda ?l?ska, Poland.
