Silver nanoparticles, being inorganic biostimulants in strawberry crops, can serve as food preservative compounds. The present research was conducted with the aim of evaluating the effect of applying silver nanoparticles via leaves and roots at increasing doses on the quality of strawberry (Fragaria x ananassa Duch.) cultivar Festival. The experiment was established in a greenhouse in the experimental agricultural field of the Chapingo Autonomous University, Texcoco, State of Mexico, in 2022 and 2023 (latitude 19.4661, longitude -98.8538). Strawberry plants of the Festival cultivar were used as plant material and placed in an open hydroponic system. The treatments of 0, 40, 80, 120, 160 and 0, 5, 10, 15, 20 mg L-1 silver nanoparticles were applied via leaves and roots, respectively. At 70 days after the start of treatments, fresh weight, firmness, pH, degrees brix, colorimetry, vitamin C, total soluble proteins, total phenols and anthocyanins were determined. The results showed that the foliar application of silver nanoparticles increased fresh weight, firmness, pH, degrees brix, colorimetry, total phenols, and anthocyanins, and the root application of silver nanoparticles increased firmness, pH, degrees brix, colorimetry, vitamin C, total soluble proteins, total phenols, and anthocyanins. The applications of silver nanoparticles via leaves and roots conclusively increased the quality indicators of strawberry fruits of the Festival cultivar; this makes silver nanoparticles a viable alternative in Mexico’s food sovereignty.
