“…As a critical stage in a plant's life cycle, germination is influenced by environmental conditions, including temperature, salinity, light, soil moisture, and The dose of nanoparticle, duration of treatment, method of application, type of nanoparticle, and plant species always have an impact on crop yield. In the case of Fe nanoparticles, they showed better results in improving nutrient uptake and germination [25,30,31] Fe 3 O 4 NPs2 increased embryo length by about 2-fold over six days (Fig. 2A).…”

“…50-100 mg/L Fe 3 O 4 NPs2 reduced metabolite levels by about 20-55%, compared to control after 6 days (Table 1). In cotyledon, at 100 mg/L Gupta et al [30] suggested that the Fe 3 O 4 NPs significantly increased starch, soluble proteins, soluble sugars, and oil content from seeds. The effects of Fe 3 O 4 NPs on seed germination and growth depended on multiple factors related to nanoparticles, such as particle size, surface chemistry, and exposure time.…”

The exposure of the seeds to environmental stresses constitutes a limiting factor that controls the success of germination and the creation of new seedlings. Germination rate and seedling growth from bean were examined after imbibition of seeds with deionized water (control), co-precipitation Fe 3 O 4 NPs1 (43 nm), or green synthesis Fe 3 O 4 NPs2 (6 nm). Fe 3 O 4 NPs increased the germination rate. The results showed that Fe 3 O 4 NPs2 had a higher positive effect on seed germination and growth compared to Fe 3 O 4 NPs1. The effects of Fe 3 O 4 NPs1 and Fe 3 O 4 NPs2 on the germination of bean seeds varied depending on NP concentrations and sizes. Fe 3 O 4 NPs2 caused higher metabolic activities (increase in amino acids and soluble sugar contents) and lower solute leakage, which controlled seed viability. Moreover, peroxidase (GPOX; EC 1.11.1.7) and dehydrogenase (EC; 1.1.1.1) activities were induced in response to NPs application, which improved defense mechanisms and reduced oxidative damage. Fe 3 O 4 NPs2 had a greater favorable effect on seed germination and growth than Fe 3 O 4 NPs1. Following nanoparticle dose control for each plant species, we advise using green synthesis NPS in the new agricultural products.
