Nanofertilizers are increasingly explored for sustainable micronutrient delivery in agriculture. Pre-treating seeds with nanofertilizers prior to planting (i.e., seed priming) reduces concerns about nanoparticle (NP) fertilizer non-target dispersion; however, priming formulations and concentrations must be carefully selected to avoid germination inhibition and toxicity. Here we investigate changes in corn seed germination and seedling development after seed priming with ZnO NPs, ZnO bulk and ZnCl₂. To evaluate the effects sterile seeds were immersed in priming solutions of 0, 20, 40, 80, 160 mg L⁻¹ Zn for the three Zn sources. Following an 8 h priming the seeds were …
