英文摘要	Tomato crop is valuable worldwide thanks to its commercial and nutritional value, which plays a very important role in the human diet. However, in arid areas, tomato crops can be found with high salt content. Salinity is a major problem for agriculture, as it decreases productivity, lowers economic yields, and induces soil erosion. The application of silicon has been observed to increase tolerance to abiotic stress and specifically to salt stress. Therefore, the aim of this study is to evaluate the application of K2SiO3 and SiO2 nanoparticles (SiO2 NPs) on the growth, antioxidant content, and tolerance to saline stress of tomato plants. Plant growth, fruit quality parameters (pH, titratable acidity, total soluble solids, firmness), antioxidant capacity (ABTS, DPPH), enzymatic (SOD, PAL, APX, CAT, GPX) and non-enzymatic (flavonoids, phenols, vitamin C, beta-carotene, lycopene) antioxidant compounds, chlorophylls, proteins, and H2O2 were evaluated. The application of SiO2 NPs at 500 mg L-1 had positive effects on the plants that were not subjected to stress, increasing the average fruit weight, fruit yield, and chlorophyll, phenol, glutathione, and GPX activity. Meanwhile, in plants under salt stress, it helped to maintain the concentration of chlorophylls, GSH, PAL activity, and vitamin C. The application of SiO2 NPs is more effective than K2SiO3 at inducing positive responses in tomato plants subjected to stress by NaCl.
