“…The results reported by Zakharova et al (2019) is comparable with our obtained results, in which wheat seeds were soaked in the presence of CuO NPs. They also reported that exposure of wheat seeds to 10ppm CuO NPs showed a 14.5% improvement in germination and a twofold increase in root and shoot length in comparison with control.…”

Seed germination is the first and the most susceptible stage in plant’s growing phases, so could be considered as an index to evaluate the effect of newly developed materials like nanoparticles (NPs), providing useful information for researchers. In our experiments, germination tests have been carried out in Petri plates, containing wet filter paper and nano-primed seeds. We had biosynthesized seven nanoparticles in our previous researches, including calcinated and non-calcinated zinc oxide, zinc, magnesium oxide, silver, copper and iron nanoparticles. The effect of these biogenic nanoparticles and their counterpart metallic salts including zinc acetate, magnesium sulphate, silver nitrate, copper sulphate and iron (III) chloride was studied on two popularly grown plants, wheat and flax, in laboratory condition to obtain preliminary information for future field experiments. Germination percentage, shoot length, root length, seedlings length, root-shoot ratio, seedling vigor index (SVI), shoot length stress tolerance index (SLSI) and root length stress tolerance index (RLSI) were calculated at 2nd and 7th days of the experiment. According to the results, the response of the plants to metal containing nanoparticles and metal salts mainly depend on type of the metal, plant species, concentration of the NP suspension or salt solution, condition of the exposure and the stage of growth.

“…They also reported that exposure of wheat seeds to 10ppm CuO NPs showed a 14.5% improvement in germination and a twofold increase in root and shoot length in comparison with control. At higher concentrations of CuO NPs, both stimulation and toxic effects were observed (decline in root length) (Zakharova et al 2019).…”

“…Also, Shawn et al [ 44 ] showed that CuO NPs at different concentrations (0.5 mM, 1.0 mM, and 1.5 mM) regularly decrease H. vulgare L. root length and shoot length with increasing NP concentrations compared to control. Similarly, Zakharova et al [ 45 ] presented results where CuO NPs at 0.01 g/L, 0.1 g/L, and 1 g/L reduced Triticum aestivum L. root length. Also, Wrigth et al [ 46 ] observed the same trend in wheat but with different CuO NP concentrations.…”

Metal nanoparticles (NPs) have an influence on plant growth and development. They can alter plant shoot and root length, fresh biomass production, and even influence the genome. Nanoparticles are also able to affect expression levels of plant microRNAs. MicroRNAs are able to protect plants from biotic stress, including pathogens which cause powdery mildew. In this study, Hordeum vulgare L. varieties “Marthe” and “KWS Olof” were grown in hydroponics with magnetic iron oxide (Fe3O4) and copper oxide (CuO) NPs added at 17, 35, and 70 mg/L. Plant morphology, genotoxicity, and expression of miR156a were investigated. The Fe3O4 and CuO NPs demonstrated different effects on the barley varieties, namely, Fe3O4 nanoparticles increased plant shoot and root lengths and fresh biomass, while CuO nanoparticles decreased them. CuO NPs presence caused larger changes on barley genome compared to Fe3O4 NPs. Thus, Fe3O4 NPs reduced genome stability to 72% in the “Marthe” variety and to 76.34% in the “KWS Olof” variety, while CuO NPs reduced genome stability to 53.33% in “Marthe” variety and in the “KWS Olof” variety to 68.81%. The miR156a expression levels after Fe3O4 NPs treatment did not change in the “Marthe” variety, but increased in the “KWS Olof” variety, while CuO NPs treatment increased miRNA expression levels in the “Marthe” variety but decrease them in the “KWS Olof” variety. As NPs are able to influence miRNA expression and miRNAs can affect the plant resistance, obtained results suggest that tested NPs may alter plant resistance response to pathogens.

The response of β-amylase in early stage germination of wheat seeds to Bacillus subtilis QM3 was mainly focused on to elucidate the promotion mechanism of B. subtilis QM3. The results showed that the changes in apparent activity of amylase and endosperm liquefaction after the strain QM3 treatment were much more obvious than that of the control group; the activity of β-amylase treated with the different concentrations of the strain QM3 increased significantly (P < 0.05) by 4% (107 CFU/mL) and 18.5% (106 CFU/mL) at the germination 6 h. Moreover, after presoaking with α-cyclodextrin, the activity of β-amylase increased significantly (P < 0.05) by 18.5% (107 CFU/mL) and 23.4% (106 CFU/mL) at the same stage of germination; the electrophoretogram of β-amylase isoenzymes showed that there is a growing trend in brightness and width of the band during the early germination from 3 to 6 h of wheat seed treated by the strain QM3 (106 CFU/mL). The increase in activity and isoenzyme expression of β-amylase may be one of the important reasons to promote the germination of wheat seeds after being treated by B. subtilis QM3.
