“…A significant effect of seed treatment on the TI of plants at all stages of the study was observed at both concentrations of SiO 2 , and after 15–25 days for Fe 3 O 4 combined with SiO 2 . The obtained data are consistent with the literature (Nazaralian et al, 2017; Yuan et al, 2018).…”

The present study assessed the toxic effects and prospects of using nanoparticles of SiO2 and Fe3O4 by studying the influence of pre-sowing priming of Pisum sativum L. seeds with a suspension of nanoparticles of SiO2 and Fe3O4 in a concentration range of 10−2 to 10−5 mg/l. The results demonstrated the stimulating effect of the SiO2 suspension (10−3 mg/l and 10−4 mg/l) and the mix of Fe3O4+SiO2 at the corresponding concentrations of 10−3 mg/l and 10−4 mg/l on the length of roots and seedlings, and the increase in the viability of plant cells under the influence of a stress factor (based on Evans blue staining). Field experience has shown the ambiguous effect of nano-printing of seeds on plant productivity.

“…Compared to the soil application of silicates, the foliar-applied silica nanoparticles appeared to be less effective [ 79 ]. On the other hand, in a comparative study with fenugreek ( Trigonella foenum-graecum L.), between soil applications of silicates versus silicon nano-particles on Si accumulation, the activity of several antioxidative stress enzymes, and the lignification of xylem cell walls, Si uptake from both soil amendments showed no difference in effectiveness [ 88 ]. This could be explained by the fact that soil-applied SiNPs are more effective than foliar-applied silica nanoparticles.…”

The use of foliar sprays with silicon compounds is relatively new. Initially (in 1990) foliar sprays with silicates were used. In 2003, foliar sprays with (stabilized) silicic acid were introduced, and more recently foliar sprays with silica nanoparticles have also been applied. Foliar sprays with silicates are effective as pesticides, while (stabilized) silicic acid sprays increase growth and yield and decrease biotic and abiotic stresses. The limited data on foliar silica-nano sprays show a tendency to decrease biotic stress and to stimulate a limited increase in growth and yield.

“…A recent study demonstrated that Si nanoparticles (SiNPs) may induce defence responses in the root system [ 25 ]. The authors demonstrated that SiNPs increased the lignification of the root cell wall in the dicot fenugreek, Trigonella foenum-graecum (Fabaceae), together with increasing the expression of the root defensive gene ( tfgd 1) [ 25 , 63 ].…”

“…Si deposition patterns within plant tissues led to the hypothesis of mechanical or physical barriers to insect feeding, as silica makes plant tissues difficult for insects to efficiently chew, penetrate and digest. In addition, silica’s beneficial roles in plant physiology, regulation of defence-related enzymes, plant hormone signalling and alteration of plant volatile blends elucidate the association of Si with biochemical/molecular defence mechanisms ([ 15 , 20 , 23 , 24 , 25 ]; Figure 1 ).…”

This paper reviews the most recent progress in exploring silicon-mediated resistance to herbivorous insects and the mechanisms involved. The aim is to determine whether any mechanism seems more common than the others as well as whether the mechanisms are more pronounced in silicon-accumulating than non-silicon-accumulating species or in monocots than eudicots. Two types of mechanisms counter insect pest attacks: physical or mechanical barriers and biochemical/molecular mechanisms (in which Si can upregulate and prime plant defence pathways against insects). Although most studies have examined high Si accumulators, both accumulators and non-accumulators of silicon as well as monocots and eudicots display similar Si defence mechanisms against insects.
