“…Also, the other components of NP Ca-Si, Si-based NPs [ 69 , 70 ], B-based NPs [ 71 ], and Fe-based NPs [ 72 , 73 ] have all been reported to have favorable effects on the growth of different plant species. It is known that Si NPs lead to different physical, biochemical, and molecular changes in plants and improve tolerance to abiotic (e.g., salinity, drought, heavy metals) and biotic stresses (e.g., pathogens, pests) [ 74 , 75 ]. Si NPs increase seed germination and seed metabolic activity during seedling emergence as well as plant growth and development by increasing gas exchange, photosynthetic rate, transpiration rate, stomatal electrical phenomenon, effective photochemical potency, photosystem II activity, and electron transport rate [ 76 ].…”

One of the main climate change-related variables limiting agricultural productivity that ultimately leads to food insecurity appears to be drought. With the use of a recently discovered nanopriming technology, seeds can endure various abiotic challenges. To improve seed quality and initial growth of 8-day-old field pea seedlings (cv. NS Junior) under optimal and artificial drought (PEG-induced) laboratory conditions, this study aimed to assess the efficacy of priming with three different nanomaterials: Nanoplant Ultra (Co, Mn, Cu, Fe, Zn, Mo, and Se), Nanoplant Ca-Si (Ca, Si, B, and Fe), and Nanoplant Sulfur (S). The findings indicate that nanopriming seed treatments have a positive impact on seed quality indicators, early plant growth, and drought resilience in field pea plants established in both optimal and drought-stressed conditions. Nevertheless, all treatments showed a positive effect, but their modes of action varied. Nanoplant Ultra proved to be the most effective under optimal conditions, whereas Nanoplant Ca-Si and Nanoplant Sulfur were the most efficient under drought stress. After a field evaluation, the examined comprehensive nanomaterials may be utilized as priming agents for pea seed priming to boost seed germination, initial plant growth, and crop productivity under various environmental conditions.

“…Many physiological and biochemical reaction are carried out inside the leaf and it is the effective in the yield under abiotic stress condition (Wang et al 2005). It is main source of carbon xation by photosynthesis and maintains the leaf temperature by transpiration through stomata (Buckley et al 2015;Yuvaraj et al 2023). The decline of leaf area surface is the rst reaction of drought adoption to reduce the transpiration losses (Larcher 2003).…”

The experimentation was carried out during the summer (2021–2022) at the Rice Department, Tamil Nadu Agricultural University, Coimbatore to assess the effects of nanosilica on drought imposed rice plants and to assess the impact of different concentrations of nanosilica (SiO2) on growth, anatomical, physio-biochemical parameters and yield characters of rice under drought conditions. In this experiment, different concentrations of the nanosilica formulation at 200, 400, 600, 800, and 1000 ppm were applied as foliar sprays under drought conditions. Spraying of 400 ppm of nanosilica formulation under drought stress in this field experiment has resulted of increases in leaf area and specific leaf weight of 14.3 and 15.3%, respectively. Application of 400 ppm nanosilica increases up to 12.5% in terms of membrane stability index (MSI), meanwhile in chlorophyll stability index (CSI) was increased up to 20.4%. Proline content was decreased up to 26.9% by application of nanosilica (400 ppm) in drought imposed treated plants. Trichome length and the length of the silica bodies were significantly increase of about 17.4 and 9.1% over the control. Application 400 ppm of nanosilica had maximum of 68.9 and 29.4% increment in terms of trichome and silicon bodies length over the drought. Stomatal structures are reduced significantly with mean reduction of 43.5% than the control in both the rice varieties. Under the drought, the average increase in stomatal size was 65.5% when 400 ppm nanosilica was applied. When exposed to 400 ppm of nanosilica treatments, CO54 showed more responses than the other variety in terms of leaf area, specific leaf weight, MSI, CSI, proline and leaf surface characteristics during drought.

“…Silicon (Si), the earth’s second most abundant element, is known to mitigate the adverse effects of salinity stress on plants by regulating physiological and biochemical processes. − For example, Muhammad et al found that spraying petunia plants with a 120 mg L –1 Si solution notably improved their photosynthetic performance and antioxidant capacity under salinity levels of 30–90 mM. While earlier studies on the role of Si in alleviating salinity stress in plants have predominantly utilized dissolved Si, there is growing interest in the application of SiO 2 NPs due to their unique properties, such as mesoporous structure, low toxicity, and facilitated nutrient availability. − Currently, SiO 2 NPs have emerged as a promising strategy for enhancing nutrient uptake, photosynthesis, and antioxidant enzyme activities in plants under various stressors, including salinity. − Furthermore, SiO 2 NPs have been found to promote root growth and development, potentially improving plants’ capacity to endure salt stress . Further investigation is required to assess the comparative efficacy of dissolved Si and nanoparticulate Si in alleviating salinity stress and to comprehend the underlying mechanisms involved.…”

In this study, 20-day-old soybean plants were watered with 100 mL of 100 mM NaCl solution and sprayed with silica nanoparticles (SiO 2 NPs) or potassium silicate every 3 days over 15 days, with a final dosage of 12 mg of SiO 2 per plant. We assessed the alterations in the plant's growth and physiological traits, and the responses of bacterial microbiome within the leaf endosphere, rhizosphere, and root endosphere. The result showed that the type of silicon did not significantly impact most of the plant parameters. However, the bacterial communities within the leaf and root endospheres had a stronger response to SiO 2 NPs treatment, showing enrichment of 24 and 13 microbial taxa, respectively, compared with the silicate treatment, which led to the enrichment of 9 and 8 taxonomic taxa, respectively. The rhizosphere bacterial communities were less sensitive to SiO 2 NPs, enriching only 2 microbial clades, compared to the 8 clades enriched by silicate treatment. Furthermore, SiO 2 NPs treatment enriched beneficial genera, such as Pseudomonas, Bacillus, and Variovorax in the leaf and root endosphere, likely enhancing plant growth and salinity stress resistance. These findings highlight the potential of SiO 2 NPs for foliar application in sustainable farming by enhancing plant-microbe interactions to improve salinity tolerance.
