Seed priming with silicon nanoparticles and nitric oxide optimizes barley growth in zinc-deficient condition: A crucial role of optimum level of endogenous nitric oxide

Key Points

• Enhanced barley growth improves under zinc-deficient conditions when treated with silicon nanoparticles and nitric oxide, leading to better nutrient uptake.
• The study observed a significant improvement in biomass and root development metrics with the application of silicon nanoparticles and nitric oxide.
• Analysis of plant growth responses demonstrates the crucial role of optimal endogenous nitric oxide levels in mitigating zinc deficiency stress.
• These findings support the potential for silicon and nitric oxide in crop management strategies to improve growth in nutrient-deficient soils.
