“…There are also several examples where Cu treatment increased seed germination, but in species other than carrot [58][59][60]. The results of our study are generally in accordance with the information in review articles summarizing the effect of nanoparticle treatment on seed germination [61,62], which emphasize the influence of the treated plant species and nanoparticle concentration on the final effect.…”

There exists a wide range of plant pathogens that are commonly referred to as seed-borne pathogens due to their dominant mode of spread. Treating seeds to eliminate such pathogens is therefore very important in contemporary seed production. In the present study, eight types of nanoparticles were evaluated for their effectiveness against Xanthomonas hortorum pv. carotae, a seed-borne pathogen that affects plants of the Apiaceae family. Initially, parameters considering the inhibitory and bactericidal activity of individual nanoparticles were evaluated under in vitro conditions. In this way, three nanoparticles based on copper, silver, and silver/selenium composite were identified as being the most effective. Subsequently, their ability to eliminate Xanthomonas hortorum pv. carotae from artificially infected carrot seeds was tested. This was achieved through the qPCR quantification of the pathogen in 14-day-old plantlets developed from seeds inoculated with Xhc. Based on the obtained results, copper-based nanoparticles were the most effective, resulting in an approximately 10-fold decrease in the occurrence of Xhc in plantlets compared to the untreated control. Taking into account the fact that X. hortorum pathovars also attack other important horticultural crops, the presented results may have a much wider scope than just carrot seeds.

“…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).…”

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.

“…Plant responses to nanoparticle exposure encompass a spectrum of morphological and physiological alterations. Key factors influencing the extent of these changes include the chemical composition, size, concentration, surface coating, reactivity of the nanoparticles, treatment duration, application method, and the type of plant species or cultivar [ 7 , 36 , 37 ]. Growth parameters and content of photosynthetic pigments provide insight into how plants react to stress caused by nanoparticles [ 38 , 39 ].…”

“…Nanoparticles' physical characteristics, encompassing size, shape, chemical composition, surface alterations, reactivity, and concentration, profoundly influence their interactions with plants [ 5 ]. Beyond these, the impact of nanoparticles depends on factors such as treatment time, application method, nanoparticle type, plant species, and cultivar [ 6 , 7 ].…”

Background The biochemical and growth changes resulting from exposure of basil (Ocimum basilicum L.) seedlings to silver nanoparticles and silver were investigated. Over a two-week period, seedlings were exposed to different concentrations (0, 40, and 80 ppm) of silver nanoparticles and silver. Results Our findings revealed that at concentrations of 40 and 80 ppm, both silver nanoparticles and silver nitrate led to decreased weight, root and shoot length, as well as chlorophyll a and b content. Conversely, these treatments triggered an increase in key biochemical properties, such as total phenols, carotenoids and anthocyanins, with silver nanoparticles showing a more pronounced effect compared to silver nitrate. Moreover, the levels of malondialdehyde (MDA) and hydrogen peroxide (H2O2) rose proportionally with treatment concentration, with the nanoparticle treatment exhibiting a more substantial increase. Silver content showed a significant upswing in both roots and leaves as treatment concentrations increased. Conclusions Application of varying concentrations of silver nanoparticles and silver nitrate on basil plants resulted in reduced growth and lower chlorophyll content, while simultaneously boosting the production of antioxidant compounds. Notably, anthocyanin, carotenoid, and total phenol increased significantly. However, despite this increase in antioxidant activity, the plant remained unable to fully mitigate the oxidative stress induced by silver and silver nanoparticles.
