Arbuscular mycorrhizal fungi (AMF) play an important role in Zn uptake by plants and can partially mitigate the effects of its deficit. On the other hand, they are involved in reducing the accumulation of Zn and its toxicity to plants when it is present in excessive concentrations in the soil. The aim of the study was to investigate the effect of two AMF, i.e., Funneliformis mosseae and Rhizophagus intraradices on Zn uptake by lettuce plants grown at two P levels and elevated concentrations of Zn in a peat substrate. The experiment demonstrated the effectiveness of mycorrhization of lettuce grown in the peat substrate; however, the arbuscular mycorrhiza did not reduce the uptake of Zn by lettuce. The AMF used in the experiment differentially affected the Zn content in lettuce. Compared to uninoculatedplants, R. intraradices increased the Zn content in lettuce, whereas F. mosseae did not affect the Zn content.
