“…In the current work, we observed that the membrane stability index (MSI) was markedly decreased by salt stress. Previously it has been shown that strawberry plants under salinity accumulated more H 2 O 2 compared to control plants, and a combination of salinity with silicon nutrition via the nutrient solution significantly ameliorated the impact of salinity on membrane integrity, lipid peroxidation and H 2 O 2 content [52].…”

“…Therefore, addition of nSiO 2 in nutrient solutions could help alleviate the negative effects of NaCl on chlorophyll content in strawberry. Inhibition of chlorophyll biosynthesis, and acceleration of its degradation and oxidative damage induced by salinity could be considered as reasons for the declining chlorophyll content [52]. Further research is needed to explore the influence of silicon on the biosynthesis of new chlorophyll and the protection of existing chlorophyll against salinity-induced oxidative stress [52].…”

Further research is needed to explore the influence of silicon on the biosynthesis of new chlorophyll and the protection of existing chlorophyll against salinity-induced oxidative stress [52]. Previous studies showed that salt stress in cowpea, kidney bean (Phaseolus vulgaris L.), faba bean (Vicia faba L.) and soybean caused significant reductions in plant growth, but Si supplementation greatly improved the growth of these plants by increasing total photosynthetic pigments and photosynthetic rate, chlorophyll content, stomatal conductance, transpiration, and intercellular carbon dioxide concentration [62].…”

Silicon application can improve productivity outcomes for salt stressed plants. Here, we describe how strawberry plants respond to treatments including various combinations of salt stress and nano-silicon dioxide, and assess whether nano-silicon dioxide improves strawberry plant tolerance to salt stress. Strawberry plants were treated with salt (0, 25 or 50 mM NaCl), and the nano-silicon dioxide treatments were applied to the strawberry plants before (0, 50 and 100 mg L−1) or after (0 and 50 mg L−1) flowering. The salt stress treatments reduced plant biomass, chlorophyll content, and leaf relative water content (RWC) as expected. Relative to control (no NaCl) plants the salt treated plants had 10% lower membrane stability index (MSI), 81% greater proline content, and 54% greater cuticular transpiration; as well as increased canopy temperature and changes in the structure of the epicuticular wax layer. The plants treated with nano-silicon dioxide were better able to maintain epicuticular wax structure, chlorophyll content, and carotenoid content and accumulated less proline relative to plants treated only with salt and no nano-silicon dioxide. Analysis of scanning electron microscopic (SEM) images revealed that the salt treatments resulted in changes in epicuticular wax type and thickness, and that the application of nano-silicon dioxide suppressed the adverse effects of salinity on the epicuticular wax layer. Nano-silicon dioxide treated salt stressed plants had increased irregular (smoother) crystal wax deposits in their epicuticular layer. Together these observations indicate that application of nano-silicon dioxide can limit the adverse anatomical and biochemical changes related to salt stress impacts on strawberry plants and that this is, in part, associated with epicuticular wax deposition.

“…In addition, the application of Si has an effect on plant nutrient uptake and it may enhance phosphorus, calcium and magnesium uptake or decrease nitrogen and potassium uptake . Fertilization with Si revealed positive responses associated with an increase in production and postharvest quality of various vegetables and fruits including lettuce, strawberry and tomato . Moreover, in a recent study it was shown that parameters related to quality attributes of fresh lettuce such as acidity, total soluble solids and vitamin C content increased with salinity, whereas Si application improved these parameters during storage .…”

BACKGROUND Using water with high salinity for plant fertigation may have detrimental effects on plant development and total yield and on the quality of the crop produced. As a possible means to alleviate the negative effects of salinity, silicon (Si) can be incorporated in the nutrient solution supplied to plants. In the present study, hydroponically grown tomato (Solanum lycopersicum Mill.) plants were subjected to two different salinity levels (0 and 50 mmol L−1 NaCl) with and without the application of Si (0 and 2 mmol L−1 K2SiO3) in order to evaluate its possible positive impact on mitigation of salinity stress‐induced symptoms. An additional experiment was implemented with postharvest Si application (sodium silicate) to investigate effects on the shelf‐life of tomato fruit. RESULTS Salinity (50 mmol L−1 NaCl) decreased plant size, total yield and fresh fruit weight while a high percentage of blossom end rot symptoms of tomato fruit was also observed. The application of Si in the nutrient solution counteracted these detrimental effects, generating a higher yield and healthier fruit (lower blossom end rot incidence) compared to the untreated plants (no application of Si). Salinity improved several quality‐related traits in tomato fruit, resulting in higher marketability, whereas the addition of Si (pre‐ and postharvest) maintained fruit firmness following storage thereby increasing the shelf‐life of tomato fruit. CONCLUSIONS These findings indicate that Si application (pre‐ and postharvest) could provide an effective means of alleviating the unfavorable effects of using low‐quality water in plant fertigation on tomato plant development, fruit yield and post‐harvest quality, through increased fruit firmness. © 2019 Society of Chemical Industry

Today, green nanotechnology has great importance due to the presence of different modes of restrictive action against various pathogens such as fungi and bacterial species. The use of nanomaterials has recently increased in agriculture and plant-tissue culture thanks to their unique different properties such as; magnetic, electrical, mechanical, optical, and chemical properties. Optimum use of iron increases protein content in the wheat grain. They also enhance plant growth by improving disease resistance and increase stability of the plants by anti-bending and deeper rooting of crops. It has been reported by many researchers that Nano-fertilizers significantly influenced the seed germination which demonstrated the effect of Nano fertilizers on seed and seed vigor. Chemical methods have been used for the synthesis of nanoparticles. Developing Nano-biotechnology is generating interests in research towards eco-friendly, cost effective and biological synthesis of nanoparticles. Nanoparticles systems have been combined into plant fungal disease controlpractices. Using nanoparticles as biosensors in plant disease diagnostics is also illustrated.
