The size of nanoparticles (NPs) allows them to accumulate in plants, and they affect plant growth by altering the size of leaves and roots and affecting their photosynthetic reactions by altering the composition of proteins in the electron transport chain, chlorophyll biosynthesis, and carbohydrate synthesis reactions. Plants play an important role on Earth as nutrient producers in all trophic food webs by producing oxygen, absorbing carbon dioxide, and synthesizing edible carbohydrates during photosynthesis. In this study, Fe3O4 and ZnO NPs at various concentrations (0, 1, 2, and 4 mg/l) were used to investigate the effect of NPs on plant morphological parameters and photosynthesis intensity, determining the amount of chlorophyll and the absorption of their light spectrum in common wheat (Triticum aestivum L.). Fe3O4 (25 nm, 2 mg/l, and 4 mg/l) and ZnO (32 nm, 4 mg/l) significantly increased the leaf length of common wheat seedlings. However, Fe3O4 NPs (25 nm, 1 mg/l, and 4 mg/l) s...

Aims: In this work we assessed Fe 2O3 nanoparticles with bulk Fe 2O3 for possible phytotoxicity and stimulative effects on wheat seed germination and early growth stage. Methodology: The treatments in the experiment were five concentrations of bulk (100, 500, 1000, 5000 and 10000 ppm) and five concentrations of nanosized Fe 2O3 (100, 500, 1000, 5000 and 10000 ppm) and an untreated control. Germination tests were performed according to the rule issued by ISTA. Analysis of variance (ANOVA) was performed between treatment samples. The information was analyzed using MSTAT-C computer software. Means compared by multiple range Duncan test and a 95% significance level (p < 0.05) was employed for all comparisons. Results: Results showed that exposure of seeds to 100 ppm iron oxide nanoparticles indicated the greatest germination rate (by 41% more than control group) related to other
Iron deficiency anaemia is a major challenge among consumers in developing countries. Given the deficiency of iron in the diet, there is an urgent need to devise a strategy for providing the required iron in the daily diet to counter the iron deficiency anaemia. We propose that iron biofortification of wheat (Triticum aestivum L.) through seed priming would be an innovative strategy to address this issue. This investigation attempts to find the interaction of iron oxide nanoparticles on germination, growth parameters and accumulation of grain iron in two contrasting wheat genotypes WL711 (low-iron genotype) and IITR26 (high-iron genotype). Wheat seeds were primed with different concentrations of iron oxide nanoparticles in the range of 25–600 ppm, resulting in differential accumulation of grain iron contents. We observed a pronounced increase in germination percentage and shoot length at 400 and 200 ppm treatment concentrations in IITR26 and WL711 genotypes, respectively. Intriguingly, the treatment concentration of 25 ppm demonstrated higher accumulation with a significant increase in grain iron contents to 45.7% in IITR26 and 26.8% in WL711 genotypes, respectively. Seed priming represents an innovative and user-friendly approach for wheat biofortification which triggers iron acquisition and accumulation in grains.
Effect of phytogenic iron nanoparticles on the bio-fortification of wheat varieties
Green Processing and Synthesis
Bio-fortification is a potential technique to tackle micronutrient deficiencies that remain. Wheat grain bio-fortification has the ability to decrease malnutrition because it represents one of the most essential staple crops. Bio-fortification is cost-effective and evidence-based sustainable technique to address malnutrition in wheat varieties possessing additional micronutrient contents. Nano-biofortification is a novel approach, enriching crops with essential nutrients in order to supplement human diets with balanced diets. The current study was designed to explore the potential role of phytogenic iron nanoparticles (Fe-NPs) to enhance nutritional contents in wheat plants to fulfill the nutrient deficiency important for human and animal health. In the current study, Fe-NPs were fabricated by using the extract of Mentha arvensis L. that were irregular in shape with an approximate size range of 40–100 nm. Further, Fourier transform infrared (FT-IR) analyses were deployed to confirm ...
Nanomagnetic Iron Oxide Solution for Fertilization on Wheat Plants
Romanian Agricultural Research
Wheat is the most cultivated plant and an important source of carbohydrates in the world. The Fe deficiency reduces quality of grain wheat leading to Fe deficiency in human. The purpose of this study was to investigate the effects of foliar and ground application of iron oxide nanoparticles (made in Romania) on growth components, yield and morphological and anatomical modifications of wheat plants. The ground application of iron oxide decreased height of plant, length of root and increased root volume and chlorophyll content more than foliar application. For the wheat plants fertilized with iron oxide nanoparticles, the decrease of root length was compensated by an increase of radicular density, which led to the development of new adventitious roots that could help the plants have a better uptake of water and nutrients. This meant that the production was not negatively influenced by the treatments performed, regardless of the application method. Our studies revealed that the fertili...
Impact of Fe3O4 nanoparticle on nutrient accumulation in common bean plants grown in soil
SN Applied Sciences, 2019
The effect of Fe 3 O 4 nanoparticles (NPs) on chemical properties of the soil rhizosphere and on the accumulation of nutrients in common bean plants was studied for two different concentrations of Fe 3 O 4 NPs. The root-to-leaves translocation index for micro-and macronutrients was calculated. The results showed that Fe 3 O 4 NP treatments had a significant effect (P < 0.05) on the chemical properties of soil rhizosphere in terms of an increase in the contents of total P, extractable P, total K, extractable K, Ca, total Mn, total Fe and cation exchange capacity and of a decrease in Cl content in soil. The treatments led to a marked increase in the accumulation of nutrients in plants by revealing a higher content of total P, K, Ca, Mn and Fe in roots, stems and leaves. In addition, the plants treated with Fe 3 O 4 NPs showed lower translocation of total Mn and Fe to stems and leaves compared with the control plants. The results indicate that Fe 3 O 4 NPs may contribute to the conversion of the insoluble forms of total P, extractable P, total K, extractable K, Ca, total Mn and total Fe in soil into soluble forms that can dissolve in the soil solution and be taken up by plants. A greater capability in the roots, stems and leaves of Fe 3 O 4-NP-treated plants to take up the nutrients suggests a beneficial effect for plant development and health. Likewise, the roots of plants treated with Fe 3 O 4 NPs absorbed and accumulated the greatest quantities of Mn and Fe compared with the control plants.

The effects of seed priming with zinc oxide (ZnO) and iron (Fe) nanoparticles (NPs) on the growth and cadmium (Cd) accumulation by wheat (Triticum aestivum) were investigated. Seeds of wheat were primed with different concentrations of either ZnO NPs (0, 25, 50, 75, and 100 mg L) or Fe NPs (0, 5, 10, 15, and 20 mg L) for 24 h by continuous aeration and then the seeds were sown in a soil which was contaminated with Cd due to long-term application of sewage water. Plants were grown till maturity under natural conditions with 60-70% moisture contents of total soil water holding capacity throughout the experiment. Plant height, spike length, and dry weights of shoots, roots, spikes, and grains were increased with NPs, in particular with the higher rates of NPs. The results depicted that NPs positively affected the photosynthesis of wheat as compared to the control. The NPs reduced the electrolyte leakage and superoxide dismutase and peroxidase activities in leaves of Cd-stressed wheat. ...

Seed priming potential of chick pea was investigated on exposure to different concentrations of Iron oxide nanoparticles (IONP). No obvious phytotoxicity was found to be shown on IONP priming whereas FeCl3, and Fe2O3 promoted adverse effects on seed priming. The germination was considerably improved on IONP priming and no significant impact on chlorophylls content observed in comparison with hydroprimed and unprimed control. Interestingly, the amount of lipophilic nonenzymatic antioxidants was increased in chick pea leaves on IONP priming at higher concentrations (150 and 200 mg L-1).

We investigated the effects of nanoscale zero-valent iron (nZVI) that has been widely used for groundwater remediation on a terrestrial crop, Medicago sativa (Alfalfa), and comprehensively addressed its development and growth in soil culture. Root lengths, chlorophyll, carbohydrate and lignin contents were compared, and no physiological phytotoxicity was observed in the plants. In the roots, using an omics-based analytical, we found evidence of OH radical-induced cell wall loosening from exposure to nZVI, resulting in increased root lengths that were approximately 1.5 times greater than those of the control. Moreover, germination index (GI) was employed to physiologically evaluate the impact of nZVI on germination and root length. In regard to chlorophyll concentration, nZVI-treated alfalfa exhibited a higher value in 20-day-old seedlings, whereas the carbohydrate and lignin contents were slightly decreased in nZVI-treated alfalfa. Additionally, evidence for translocation of nZVI into plant tissues was also found. Vibrating sample magnetometry on shoots revealed the translocation of nZVI from the root to shoot. In this study, using an edible crop as a representative model, the potential impact of reactive engineered nanomaterials that can be exposed to the ecosystem on plant is discussed.
