Response of Maize Seedlings to Silicon Dioxide Nanoparticles (SiO₂NPs) under Drought Stress.

ABSTRACT: Recently, the use of nanofertilizers has received a great deal of attention in managing plants under biotic and abiotic stresses. However, studies that elucidate the role of silicon dioxide nanoparticles (SiO₂NPs) in regulating maize tolerance to drought stress are still at early stages of development. In this study, plants that were treated with SiO₂NPs (0.25 g/L as foliar spray) displayed considerable improvement in the growth indices, despite being subjected to drought stress. In addition, the action of SiO₂NPs led to a considerable rise in the levels of chlorophylls, proline, cell membrane integrity, leaf water content, and antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT), and guaiacol peroxidase (G-POX)). In contrast, an inverse trend wa
