“…Higher accumulation of Si upon foliar spray application in plants was reported at the whole plant level, and an enhanced accumulation of Si concentration was observed in leaves [25,45]. The quanti cation of Si using both SEM-EDS and spectrophotometer analysis in our study provided the knowledge to understand the e cient Si treatment combination and Si partition in the different plant tissues, similar to previous studies [42,46,47]. Upon Si treatment, the higher accumulation of Si in the leaf tissues in 2 mL treatment strengthened the morpho-physiological and yield traits [47].…”

“…Various methods are available for qualitative and quantitative analysis of Si presence in plant samples [30]. However, among these, visualization methods with quanti cations provide a simple and reliable approach to assessing the localization of Si in various plant parts [41,42]. Similar visualization observations resulting from SEM-EDS image analysis in the present study assist in understanding the mechanisms of absorption and translocation of Si to various plant parts.…”

Purpose: Strawberries are a high-value crop in the United States due to their increasing demand and nutritional benefits. However, strawberry plants are delicate and sensitive to abiotic and biotic factors and prone to gray mold caused by Botrytis cinerea during harvest and post-harvest operations, leading to significant economic losses. Fungicides are effective but raise concerns about residues and the evolution of fungal resistance, limiting their use. Hence, developing alternative approaches is critical for improving the strawberry plant's resilience and solutions to combat gray mold fungus. Methods: To assess the potassium silicate efficacy on agronomic traits, two strawberry cultivars (Flavorfest and Rutgers ScarletTM) growing under high tunnel conditions were foliar sprayed with different doses (0, 2, 3, and 4mL per gallon of water) in five applications in the fall of 2018 as well as in the spring of 2019. Silica accumulation in the plant samples was determined using Scanning Electron Microscope images coupled with an Energy Dispersive Spectrometer (SEM-EDS) analysis and spectrophotometer method. An in-vitro experiment was used to determine antifungal activity against B. cinerea. Results: Strawberry leaf samples treated with 2 mL per gallon had higher silica concentrations and phytolith production, which strengthened the aerial parts, reduced translocation to roots, and significantly boosted plant width and marketable yield compared to other treatments. Furthermore, treatment with 2 mL potassium silicate significantly reduced the growth of the B. cinerea. Conclusion: Our findings suggest that potassium silicate provides potential options to improve the agronomic traits in strawberries and preventative measures against B. cinerea.
