“…Similar results for the better effect of Si-NPs compared to Si were reported on wheat seedling under UV-B stress [15]. The similar enhancement in biomass of Si-NPs-treated plants was reported in various studies [5,7,26]. The Si-NPs may improve the nutrients uptake by plants, which results in higher biomass.…”

“…In this regard, Si-NPs increases the uptake of Mg, P, K and S contents in stressed plants [26,27]. Moreover, plant biomass may be remarkably improved by Si-NPs which might be due to its placement in the leaf bundle that affect the structure of chloroplasts and leaf yield at the unit level and therefore increase the plant's ability to use light [5].…”

“…It is considered as the second abundant element in earth crust after oxygen [4]. The positive effect of Si on plant growth and development under biotic and abiotic stress conditions have been well documented [1,5]. Si stimulates plant growth through improving nutrients uptake, water content, and the resistance to pathogens and diseases [5].…”

“…The importance of nanofertilizers is due to their rapid and complete absorption by plants [8,12]. The positive effects of foliar application with Si-NPs on plant growth and development under heavy metal [5,7,13,14], UV radiation [15], salinity [16], and drought [4]. However, little is known about involvement of Si and its nanoparticles (Si-NPs) in the regulation of drought effects in plants.…”

Purpose Silicon (Si) plays beneficial role in alleviating biotic and abiotic stresses but comparative investigations with Si nanoparticles (Si-NPs) under water restriction on medicinal plants is not recognized. The aim of this study was to observe the Si and Si-NPs effects on growth, physio-chemical attributes, and essential oil (EO) profile in aerial parts of coriander (coriandrum sativum L.) under water stress. Methods A split-plot experiment was conducted with irrigation regimes (irrigation after 60, 90, and 120 mm evaporation from Class A pan) in the main plots and foliar application of Si (in the form of Na2SiO3) and Si-NPs in the subplots during 2019 and 2020. Results The results represented drought particularly severe stress decreased biological yield and relative water content (RWC) but increased total soluble sugar (TSS). Both Si and Si-NPs improved plant growth and yield through improved RWC, TSS, total phenolic content (TPC) and total flavonoid content (TFC). Moderate drought stress with Si-NPs was highly effective on TPC, TFC, EO percentage and yield. The main EO constitutes were n-Decanal (20.8-27.6%), 2E-Dodecanal (13.3-16.7%), 2E-Decanal (13.9-18.7%), 2E-Tridecen-1-al (7.3-10.5%), Dodecanal (7.2-10.6%), and n-Nonane (4.3-8.7%). Heat map analysis (HMA) showed foliar application of Si and Si-NPs were significantly distinguished from control treatment, which was mainly explained by EO yield and TFC attributes. Conclusion Foliar-applied Si-NPs was the rapidly and highly effective practice to reach the optimum antioxidant capacity and EO yield of coriander plants when experience moderate drought stress.
