“…Phytolith denotes phyto (plant) and lithos (stone); both originated from Greek. Si application-induced phytolith formation in plants is reported to strengthen the plant tissues and act as a mechanical barrier against pests and regulations of nutrient uptake and abiotic and biotic stress tolerance [43,44].…”

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.

The development and production of secondary metabolites from priceless medicinal plants are restricted by drought stress. Mentha pulegium L. belongs to the Lamiaceae family and is a significant plant grown in the Mediterranean region for its medicinal and aesthetic properties. This study investigated the effects of three polyethylene glycol (PEG) (0, 5, and 10%) as a drought stress inducer and four silicon nanoparticle (SiNP) (0, 25, 50, and 100 ppm) concentrations as an elicitor to overcome the adverse effect of drought stress, on the growth parameters and bioactive chemical composition of M. pulegium L. plants grown in vitro. The experiment was performed as a factorial experiment using a completely randomized design (CRD) consisting of 12 treatments with two factors (3 PEG × 4 SiNPs concentrations), 6 replicates were used for each treatment for a total of 72 experimental units.The percentage of shoot formation was inversely proportional to the PEG concentration; for the highest PEG concentration, the lowest percentage of shoot formation (70.26%) was achieved at 10% PEG. SiNPs at 50 ppm enhanced shoot formation, the number of shoots, shoot height, fresh and dry weight, rosmarinic acid, total phenols, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity. The methanol extract from M. pulegium revealed the presence of significant secondary metabolites using gas chromatography‒mass spectrometry (GC–MS). The principal constituents of the extract were limonene (2.51, 2.99%), linalool (3.84, 4.64%), geraniol (6.49, 8.77%), menthol (59.73, 65.43%), pulegone (3.76, 2.76%) and hexadecanoic acid methyl ester or methyl palmitate (3.2, 4.71%) for the 0 ppm SiNPs, PEG 0% and 50 ppm SiNPs, and PEG 10%, respectively. Most of the chemical components identified by GC‒MS in the methanol extract were greater in the 50 ppm SiNP and 10% PEG treatment groups than in the control group. SiNP improves drought tolerance by regulating biosynthesis and accumulating some osmolytes and lessens the negative effects of polyethylene glycol-induced drought stress.Based on the results, the best treatment for most of the parameters was 50 ppm SiNPs combined with 10% PEG, the morphological and chemical characteristics were inversely proportional to the PEG concentration, as the highest PEG concentration (10%) had the lowest results. Most parameters decreased at the highest SiNP concentration (100 ppm), except for the DPPH scavenging percentage, as there was no significant difference between the 50 and 100 ppm SiNPs.
