摘要： Nanoselenium is an important pleiotropic and non-toxic signaling molecule with multiple roles in regulating plant responses to environmental stresses. The aim of this study was to explore the effect of nanoselenium on the soluble solids content and antioxidant capacity of kiwifruit. The effects of nanoselenium on kiwifruit's antioxidant capacity and soluble solids content were investigated by foliar spraying at different concentrations during a two-year field trial. We demonstrated that nanoselenium (15 mg/L) was the most effective treatment strategy, resulting in increased total soluble solids content (34.9%), as well as increased selenium (0.025 mg/kg), superoxide dismutase (25.9%), peroxidase (22.5%) and catalase (29.5%) content in kiwifruit. In addition, nanoselenium treatment activated the signal transduction and galactose pathways of the plant and increased the expression of genes related to secondary metabolism. These changes led to higher antioxidant and sugar levels, enhancing the taste of the selenium-enriched kiwifruit. This study established a nanoselenium agricultural strategy to improve kiwifruit's value and functionality.
