Potato (Solanum tuberosum L.) is one of the world’s most important staple crops, providing
essential carbohydrates and nutrients. In vitro regeneration of potato via callus induction is a critical
step in genetic transformation, tissue culture propagation, and crop improvement programs. Recent
studies have demonstrated that nanoparticles can influence plant tissue culture responses by
modulating cellular metabolism, nutrient availability, and oxidative stress. This study investigates the
effect of iron oxide nanoparticles (Fe₃O₄ NPs) on callus induction and regeneration efficiency in
potato cv. Arizona . Different concentrations of Fe₃O₄ NPs were incorporated into Murashige and
Skoog (MS) medium to evaluate their influence on callus formation frequency, callus growth rate,
and subsequent shoot regeneration. The results indicated that low concentrations of Fe₃O₄ NPs
significantly enhanced callus induction and shoot regeneration compared to the control, suggesting a
potential role of iron nanoparticles in improving in vitro culture efficiency. These findings provide a
basis for integrating nanotechnology into potato tissue culture protocols to accelerate crop
improvement programs.
