Silicon nanoparticles (SiNPs) in sustainable agriculture: major emphasis on the practicality, efficacy and concerns

Abstract

Silicon (Si), a beneficial element for plants, is known for its prophylactic effect under stress conditions. Many studies have documented the role of biogenic silica (bulk-Si) in alleviating biotic and...

Iodine and Selenium Biofortification of Chervil Plants Treated with Silicon Nanoparticles

“…The phenomenon of V, Cr and Al increase does not cause any ecological risks due to rather low levels of these elements and indicates the possibility of nano-Si participation in the element distribution. Notably, foliar nano-Si effect on Al accumulation in chervil plants contrasts with the Al accumulation decrease under soil Si application [43].…”

“…Taking into account the non-significant Si accumulation in chervil plants as a result of low Si dose applied, its beneficial effect on growth, iodine accumulation and nutritional value of this crop is surprising. Indeed, most of investigations which reported Si growth promoting activity focused on the application of high Si concentrations, resulting in significant plant accumulation of this element [43]. In this respect, the close relationship between Si and plant hormonal status may be a possible explanation of this phenomenon.…”

Nanosilicon alters oxidative stress and defence reactions in plants: a meta-analysis, mechanism and perspective

“…61 Moreover, roots release many exudates, which could form complexes with NMs and then bind to membrane transporters or carrier proteins through ion channels and water channels, or are endocytosed. 56 The efficacy of NMs in mediating gene expression can also depend on the type of Si NMs applied. 15 Since plants cannot directly utilize the applied Si NMs, they can only utilize the silicic acid formed by the transformation of Si NMs.…”

Silica nanoparticles as novel sustainable approach for plant growth and crop protection

“…The primary premise behind SiNPs use in agriculture is to reduce hazardous environmental inputs and excessive fertilizer costs because they are made using greener concepts and will mitigate the negative effects of chemical fungicides. Due to executive characteristics such as large surface area and small dimension, SiNPs have agricultural potential, ensuring realistic dispersion in plant tissues (Bhat et al, 2021). Scientists have explored the research and utilization of NPs as soil stabilizers.…”
