“…From our results, we concluded that the use of Nanosilicon was more efficient with the lower level of salinity (1750ppm) in both tested cultivars, where it caused a significant increase in the SCC and polyphenols contents in the leaves of seedlings. Such findings confirmed that Si and Nano-silicon application mitigate the adverse of salinity and increased polyphenol and SCC (Abdel-Haleim et al, 2017& Abou-shlell et al, 2020. Phenolic compounds defend plants against a number of biotic and abiotic stresses.…”

“…At the high salinity level, salts may build up in the apoplast and dehydrate the cell and inhibit enzymes in cytoplasm or they may exert a direct toxic effect in chloroplast and photosynthetic processes (Munns & Tester, 2008). Also, salinity stress increase of toxic ions (Na + ) in leaf and thus increase ROS and caused oxidative stress and damage chloroplast (Abou-shlell et al, 2020). Treating seedlings with Nano-silicon improved the leaf studied pigments content (total chlorophylls and carotene) in seedlings of the two tested mango cultivars under different levels of salinity.…”

The experiment was carried out in two consecutive seasons (2017/18 and 2018/19) on 'Sukkary' and 'Gahrawy' mango root-stocks seedlings and the purpose of the research was to investigate the effectiveness of applying Nano-silica to increase the tolerance of 'Gahrawy' and 'Sukkary' mango rootstocks. The tested treatments were tap water irrigation (TWI),TWI and spraying Nano silicon (SNSi) at 1.0g/L,Sea water irrigation (SWI) at 1750ppm, SWI at 1750ppm and SNSi, SWI at 3500ppm, and SWI at 3500ppm and SNSi. Foliar sprays of Nano-silicon were done four times;the first at the beginning of the experiment, and then three times at 45-days intervals.The effect of treatments on the behavior of the seedlings of the two rootstocks including vegetative characteristics (new leaf area, seedling height increase%, seedling stem diameter increase, root length and width, number of lateral and secondary roots and root growth coefficient), physiological parameter "Leaf pigments, total phenols and soluble carbohydrates contents",leaf mineral contents " N, P, K, Na, Ca and Mg" and Non-enzymatic antioxidants"proline content and DPPH" as well as salinity symptoms parameters were studied. Increasing levels of salinity caused a decrease in most parameters and an increase in the sodium and proline content, and salinity symptoms of the leaves. Irrigation with salty water at 1750ppm together with foliar spraying Nano-silicon enhanced leaf content of pigments, soluble carbohydrate and total phenols, Mg, N, P, K and decreasing of salinity symptoms parameters.The results confirmed that the effects of Nano-silicon on the behavior of treated seedlings differ according to the variety under salinity conditions.

“…The same trend was encountered in the 2 nd season. Similarly, Abou-shlell et al (2020) reported that photosynthesis pigments were increased in moringa plants affected by NaCl stress after foliar spray with nano-silicon at concentration of 60 mg -1 compared to control untreated plants. Because of the improved carbonic anhydrase activity and photosynthetic pigment synthesis, SiO 2 NP treatments significantly increased photosynthesis rates (Siddiqui and Al-Whaibi, 2014).…”

The aim of this study was to evaluate some physiological parameters and biochemical changes in common bean plants (Phaseolus vulgaris) as a result of the foliar spraying of some nano stimulants (silicon, polyamine, seaweed and biofertilizer) under salt stress conditions. The pot experiment was conducted in the Agriculture Faculty's greenhouse at Menoufia University in Shibin El-Kom, Egypt during the two summer seasons of 2019 and 2020. Salt stress at level 6 dS/m significantly decreased growth, physiological characteristics, photosynthetic pigments, chemical measurements, and yield parameters. Meanwhile, the use of nano stimulators reduced the adverse effects of salinity by improving water relations, chlorophyll, enzymatic antioxidants (peroxidase and polyphenoloxidase), non-enzymatic antioxidants defense system (carotene, total soluble sugars, total amino acids, and proline), N, P and K and decreased Na+ concentrations resulted in high seed yield, particularly with nano silicon followed by nano biofertilizer. As the level of salinity increased, the seed weight (g/plant) decreased significantly by about 40% at the salt level 6 dS/m. In comparison to the control, using nano silicon resulted in significant increases in the leaf area, relative water content, proline concentration and seed weight by about 84, 53, 49 and 91%, respectively at 6 dS/m salinity level. To mitigate the negative impacts of salinity and improve the production, this study suggests spraying common bean plants with nano silicon followed by nano biofertilizer.

Salt stress is identified as a significant abiotic stress that hampers agricultural sustainability globally. The study was carried out to investigate the potential mitigating effects of selenium nanoparticles (Se-NPs) on salt stress in soybean. Two weeks old grown soybean seedlings were subjected to salt stress conditions (4000 mg L− 1 of sea salts). The plants were foliar sprayed with Se-NPs at concentrations of 0.0, 0.5, 1.0 and 1.5 mg L− 1 twice. The first application was applied at four weeks from sowing and the second application was added after two weeks from the first application. Compared to control, Se-NPs application mitigates the negative effect of salinity on plant growth to a variable extent. This improvement may be attributed to several factors such as increased the concentrations of photosynthetic pigments, total soluble sugars and total protein. In addition, Se-NPs alleviated the adversely effect of oxidative stress by increasing the antioxidant activities and potassium contents without markedly increase in the sodium content of the soybean leaf tissues. Also, Se-NPs enhanced the biosynthesis of secondary metabolites such as total phenolic content under salinity. Moreover, Se-NPs spray significantly reinforced the development of conducting secondary tissues in the leaves and roots of the treated plants. GmHKT1 gene transcription was markedly up-regulated in salinized soybean and foliar sprayed with Se-NPs as a molecular strategy to cope with the salinity. Based on the obtained results, among the different doses of Se-NPs, soybean plants sprayed with 1.0 mg L− 1 Se-NPs showed better salt tolerance. The foliar spray of Se-NPs may be considered as a promising approach to enhance salt tolerance in soybean plants, which could have significant implications for improving agricultural sustainability in salt-affected regions.
