“…Mesoporous SNPs were shown to boost the growth, total protein content and photosynthesis of lupin and wheat seedlings and to induce no changes in the activity of antioxidant enzymes (Sun et al, 2016). Interestingly in this study, the authors observed a shift of 14 cm -1 and 10 cm -1 in the Raman peaks of chlorophyll from wheat and lupin when isolated chloroplasts were incubated with MSNPs suggesting a change in the molecular structure of chlorophyll.…”

Elemental silicon (Si), after oxygen, is the second most abundant element in the earth’s crust, which is mainly composed of silicates. Si is not considered essential for plant growth and development, however, increasing evidence in the literature shows that this metalloid is beneficial to plants, especially under stress conditions. Indeed Si alleviates the toxic effects caused by abiotic stresses, e.g., salt stress, drought, heavy metals, to name a few. Biogenic silica is also a deterrent against herbivores. Additionally, Si ameliorates the vigor of plants and improves their resistance to exogenous stresses. The protective role of Si was initially attributed to a physical barrier fortifying the cell wall (e.g., against fungal hyphae penetration), however, several studies have shown that the action of this element on plants is far more complex, as it involves a cross-talk with the cell interior and an effect on plant metabolism. In this study the beneficial role of Si on plants will be discussed, by reviewing the available data in the literature. Emphasis will be given to the protective role of Si during (a)biotic stresses and in this context both priming and the effects of Si on endogenous phytohormones will be discussed. A whole section will be devoted to the use of silica (SiO2) nanoparticles, in the light of the interest that nanotechnology has for agriculture. The paper also discusses the potential technological aspects linked to the use of Si in agriculture and to modify/improve the physical parameters of plant fibers. The study indeed provides perspectives on the use of Si to increase the yield of fiber crops and to improve the thermal stability and tensile strength of natural fibers.

“…Silica nanoparticles were successfully used as nanosensors for the detection of various metals in soil. The core–shell structure of silica nanoparticles provides immense advantages over the other nanoparticles in terms of sensor stability, accuracy, and sensitivity (Sun et al 2016 ). When combined with the other nanoparticles, silicon has the potential to improve stability and sensitivity; by firmly attaching well-separated silver nanoparticles on the silica surface, optical stability and sensitivity in suspensions are improved, and the thin-film structural configuration acts as a colloidal stabilizer and a spacer for the spatial stabilization of silver nanoparticles (Jean et al 2010 ).…”

The beneficial effects of silicon and its role for plants are well established; however, the advantages of silicon nanoparticles over its bulk material are an area that is less explored. Silicon nanoparticles have distinctive physiological characteristics that allow them to enter plants and influence plant metabolic activities. The mesoporous nature of silicon nanoparticles also makes them good candidates as suitable nanocarriers for different molecules that may help in agriculture. Several studies have shown the importance of silicon nanoparticles in agriculture, but an overview of the related aspects was missing. Therefore, this review brings together the literature on silicon nanoparticles and discusses the impact of silicon nanoparticles on several aspects of agricultural sciences. The review also discusses the future application of silicon nanoparticles in plant growth, plant development, and improvement of plant productivity.

“…Although silicon is abundant in the soil, but its absorbable form is very low. From the last two decades there is growing evidence that show silicon nanoparticles can be introduced as one of the elite compounds for the enhancement of agricultural yields (Ma et al 2001;Ma 2004;Ma & Yamaji 2006;Zhang & Fang 2010;Gerami & Rameeh 2012;Van Bockhaven et al 2013;Zhu & Gong 2014;Coskun et al 2016;Sun et al 2016;Janmohammadi et al 2017). Silicon (Si) has not been proven to be an essential element for higher plants, but its beneficial effects on growth have been reported in a wide variety of crops, including rice, wheat, barley, and cucumber (Ma et al 2001).…”

Current experiment was conducted to investigate the effects of foliar application of different nutrients (control, nano-chelated Fe, nano-chelated Zn, nano-TiO2, nano-Si) on seed yield and morpho-physiological characteristics of oilseed rape cultivars (Hydromel, Neptune, Nathalie, Danube, Alonso). The highest pod numbers was achieved by foliar application of Zn and nano-SiO2 in cv. Hydromel and Neptune. The heaviest seeds were recorded for plants treated with nano-SiO2. The highest seed yield was recorded for cv. Hydromel and Neptune treated with Fe and nano-TiO2. The highest indole acetic acid was recorded in cv. Hydromel treated with Zn and nano-SiO2. The evaluation of plant pigments revealed that foliar application of nano-SiO2 and TiO2 significantly increased the concentration of carotenoids and Chlorophyll a, b. Overall, the results indicate that cultivating the high yielding hybrids (Hydromel, Neptune, Nathalie) along with the application of iron, SiO2 and TiO2 nano-particles can greatly improve plant performance
