Summary

The role of arbuscular mycorrhizal fungus Glomus intraradices in 134Cs isotope uptake by different plant species is studied. The impact of radiocaesium on mycorrhizal development and functioning of plant photosynthetic apparatus is considered. The possibility of mycorrhizal symbiosis application in phytoreme-diation of radioactively contaminated areas is analyzed. It is found that colonization of plants with arbuscular mycorrhizal fungus resulted in significant decrease of radiocaesium concentration in their aboveground parts, while it did not have considerable impact on the radionuclide uptake by plant root system.

Keywords: radiocaesium, radioactive contamination of environment, arbuscular mycorrhiza, arbuscu-lar mycorrhizal fungi, plant photosynthetic apparatus, mycorrhizal colonization, phytoremediation.
