Conclusions
It is appeared from this study that there is a potential for mycorrhiza to be used on sites contaminated by radiocesium. Among mycorrhizal plants sunflower (Helianthus spp.) grown on soil inoculated with the AM fungus G. mosseae appears a plant species/AM fungal strain association that substantially increases 137Cs uptake on contaminated loamy and loamy sand soils. However, the response of plants to 137Cs uptake after soil inoculation is conditional and requires future studies to determine the role of other factors, such as nutrient status and pH. The beneficial effects of mycorrhizal inoculation raise the awareness of the role of AM fungi in field conditions, where concomitant colonization can be expected. The inoculation experiments with specific “non-native” mycorrhizal fungus on the uptake of 137Cs need to be tested in field conditions.
