“…The current results regarding pronounced growth of rice plants in response to AgNPs treatment are in accordance with findings of Iqbal et al [30] as they observed increase in root and shoot length and leaf area in wheat plants due to AgNPs. The same results were also obtained by Thuesombat et al [32], Hao et al [33], and Ndeh et al [31] in rice plants in response to silver, iron, and gold nanoparticles. This growth‐stimulating effect of NPs varies from plant to plant [34].…”

This study was organised to check the effect of silver nanoparticles and silver nitrate on rice growth against biotic stress. Silver nanoparticles were synthesised by using plant extract as reducing agent, followed by characterisation through UV Vis spectroscopy, XRD, EDS and SEM. Aspergillus application significantly reduced rice plant fresh mass (0.9%), dry mass (0.21%), root length (2.3%), shoot length (5.2%) and root number (1%) in comparison to control. Similarly, leaf area, leaf fresh mass, dry mass and leaf number were also reduced by 23.1, 0.02, 0.11 and 0.9%, respectively. AgNPs and AgNO treatments increased the root length (16.2 & 12.8%), shoot length (21 & 20%), root number (8.1 & 6.8%), plant fresh weight (6.4 & 5%) and plant dry weight (4.6 & 3.5%) in 75mg/l treatment of AgNPs and AgNO respectively. Similarly, AgNPs and AgNO treatment (75 mg/l concentrations) reflected remarkable increase in leaf area (58.8 & 57.2 %), leaf number (4.3 & 3.7 %), leaf fresh weight (1.7 & 1.4 %) and leaf dry weight (0.9 & 0.8 %). Overall AgNPs showed more significant results as compared to AgNO. The quantity of aflatoxins ranged from 3.1 to 7.7 μg/kg against tolerable limit (4 µg/kg). Overall AgNPs and AgNO treatments showed significant results and it could be considered as a strategy for aflatoxin management in rice plants.

“…Its promotive impact was established in the germination tests of Alyssum homolocarpum, Nigella sativa and Salvia mirzayanii ([ 111 ], Table 1 ). In other experiments executed on onion [ 125 ], white mustard [ 111 ] and rice [ 123 ], lower concentrations (10–100 mg L −1 , depending on plant species) were found to be stimulative for germination or root growth while higher doses proved to be toxic ( Table 2 ). Absolutely deleterious aspects of TiO 2 NPs were presented in Vicia narbonensis and maize seedlings, where root growth inhibition induced by NPs was due to chromosomal aberrations in root tip meristem cells ([ 138 ], Table 3 ).…”

Due to recent active research, a large amount of data has been accumulated regarding the effects of different nanomaterials (mainly metal oxide nanoparticles, carbon nanotubes, chitosan nanoparticles) on different plant species. Most studies have focused on seed germination and early seedling development, presumably due to the simplicity of these experimental systems. Depending mostly on size and concentration, nanomaterials can exert both positive and negative effects on germination and seedling development during normal and stress conditions, thus some research has evaluated the phytotoxic effects of nanomaterials and the physiological and molecular processes behind them, while other works have highlighted the favorable seed priming effects. This review aims to systematize and discuss research data regarding the effect of nanomaterials on germination and seedling growth in order to provide state-of-the-art knowledge about this fast developing research area.

“…The effect of Fe 3 O 4 NPs was more prominent at the seed germination stage because at a lower concentration Fe 3 O 4 NPs acts as a nutrient for seed growth [ 11 , 16 , 17 ]. It was reported that silicon regulates the growth parameters in plants under arsenic stress [ 16 , 18 ].…”

Arsenic (As) contamination has emerged as a serious public health concern worldwide because of its accumulation and mobility through the food chain. Therefore, the current study was planned to check the effect of Bacillus subtilis-synthesized iron oxide nano particles (Fe3O4 NP) on rice (Oryza Sativa L.) growth against arsenic stress (0, 5, 10 and 15 ppm). Iron oxide nanoparticles were extracellular synthesized from Bacillus subtilis with a desired shape and size. The formations of nanoparticles were differentiated through UV-Visible Spectroscopy, FTIR, XRD and SEM. The UV-Visible spectroscopy of Bacillus subtilis-synthesized nanoparticles showed that the iron oxide surface plasmon band occurs at 268 nm. FTIR results revealed that different functional groups (aldehyde, alkene, alcohol and phenol) were present on the surface of nanoparticles. The SEM image showed that particles were spherical in shape with an average size of 67.28 nm. Arsenic toxicity was observed in seed germination and young seedling stage. The arsenic application significantly reduced seed germination (35%), root and shoots length (1.25 and 2.00 cm), shoot/root ratio (0.289), fresh root and shoots weight (0.205 and 0.260 g), dry root and shoots weight (6.55 and 6.75 g), dry matter percentage of shoot (12.67) and root (14.91) as compared to control. Bacillus subtilis-synthesized Fe3O4 NPs treatments (5 ppm) remarkably increased the germination (65%), root and shoot length (2 and 3.45 cm), shoot/root ratio (1.24) fresh root and shoot weight (0.335 and 0.275 mg), dry root and shoot weight (11.75 and 10.6 mg) and dry matter percentage of shoot (10.40) and root (18.37). Results revealed that the application of Fe3O4 NPs alleviated the arsenic stress and enhanced the plant growth. This study suggests that Bacillus subtilus-synthesized iron oxide nanoparticles can be used as nano-adsorbents in reducing arsenic toxicity in rice plants.
