Abstract: The effect of silver nanoparticles (AgNPs) on plant cells, since their phytotoxicity potential is not yet fully understood. In this context, the aim of the present study was to elucidate the effects of AgNPs in the in vitro culture of Physalis peruviana. For this purpose, P. peruviana seeds were grown in MS medium supplemented with different concentrations of AgNPs. Growth and development of seedlings were evaluated through germination, seedling size and biomass and biochemical and anatomical analyses. At the end of 60 days of cultivation, it was observed that the in vitro germination of this species is not affected by the presence of AgNPs and that at low concentrations (0.385 mg L−1) it can promote an increase in seedlings biomass. However, higher concentration (15.4 mg L−1) leads to a reduction in seedling size and root system, but no changes were observed in the seedlings antioxidant metabolism and anatomy. These results demonstrate that the phytotoxicity of AgNPs in P. peruviana is related to the concentration of nanoparticles to which the specie is exposed.
