“…36 Altogether, our data indicate that seed priming with iron oxide nanoparticles is able to stimulate root growth as well as to increase the plant vegetative growth in Capsicum annuum, confirming the stimulatory effects of nanoparticle-mediated seed priming already reported in different plant species. 14,37,38 Therefore, as seed priming is a pivotal phase in seed preparation, focused on achieving optimal germination and early seedling establishment, the adoption of MNPs in this step may offer substantial benefits to seed companies and nurseries.…”

“…However, the application of higher nano-priming concentrations of ferric oxide (Fe 2 O 3 ) NPs was found to disrupt chloroplast structure and reduce photosynthesis in Kobresia capillifolia (Decne.) C.B.Clarke, including a decrease in starch accumulation [27]. Altogether, the positive or negative impact of metallic NPs on chlorophyll synthesis, including overall photosynthesis, was found to be dependent on their type, concentration used, and plant genotypes [12,15].…”

“…It has been hypothesized that ZnO NPs modulated chlorophyll synthesis by being involved in protochlorophyllide formation [51]. Seed priming with Fe NPs promoted chlorophyll synthesis and chloroplast metabolism and thereby improved carbon assimilation [27]. At optimal doses, Fe 2 O 3 NPs increased the conversion efficiency of primary light energy of PS II (Fv/Fm) and water use [27].…”

In today’s time, agricultural productivity is severely affected by climate change and increasing pollution. Hence, several biotechnological approaches, including genetic and non-genetic strategies, have been developed and adapted to increase agricultural productivity. One of them is nano-priming, i.e., seed priming with nanomaterials. Thus far, nano-priming methods have been successfully used to mount desired physiological responses and productivity attributes in crops. In this review, the literature about the utility of nano-priming methods for increasing seed vigor, germination, photosynthetic output, biomass, early growth, and crop yield has been summarized. Moreover, the available knowledge about the use of nano-priming methods in modulating plant antioxidant defenses and hormonal networks, inducing salinity tolerance and disease resistance, as well as alleviating heavy metal toxicity in plants, is reviewed. The significance of nano-priming methods in the context of phytotoxicity and environmental safety has also been discussed. For future perspectives, knowledge gaps in the present literature are highlighted, and the need for optimization and validation of nano-priming methods and their plant physiological outcomes, from lab to field, is emphasized.

“…For example, the germination rate of rapeseed increased by 12% under 200 mM of salt stress ( Khan et al., 2021 ). As for the priming treatment, the phenomenon of seed germination and seedling growth first increasing and then decreasing with the increase of priming concentration ( Figures 3C, D ) is often considered to be associated with the toxicity of high-concentration nanomaterials to plants ( Sun et al., 2023 ). In addition, the high osmotic potential of higher-concentration priming solutions may reduce water absorption and hinder germination.…”

Soil salinization is a common environmental problem that seriously threatens crop yield and food security, especially through its impact on seed germination. Nanoparticle priming, an emerging seed treatment method, is receiving increasing attention in improving crop yield and stress resistance. This study used alfalfa seeds as materials to explore the potential benefits of cerium oxide nanoparticle (CeO2NP) priming to promote seed germination and improve salt tolerance. CeO2NPs at concentrations up to 500 mg/L were able to significantly alleviate salt stress in alfalfa seeds (200 mM), with 50 mg/L of CeO2NP having the best effect, significantly (P< 0.05) increasing germination potential (from 4.0% to 51.3%), germination rate (from 10.0% to 62.7%), root length (from 8.3 cm to 23.1 cm), and seedling length (from 9.8 cm to 13.7 cm). Priming treatment significantly (P< 0.05) increased seed water absorption by removing seed hardness and also reducing abscisic acid and jasmonic acid contents to relieve seed dormancy. CeO2NP priming increased α-amylase activity and osmoregulatory substance level, decreased reactive oxygen species and malonaldehyde contents and relative conductivity, and increased catalase enzyme activity. Seed priming regulated carotenoid, zeatin, and plant hormone signal transduction pathways, among other metabolic pathways, while CeO2NP priming additionally promoted the enrichment of α-linolenic acid and diterpenoid hormone metabolic pathways under salt stress. In addition, CeO2NPs enhanced α-amylase activity (by 6.55%) in vitro. The optimal tested concentration (50 mg/L) of CeO2NPs was able to improve the seed vigor, enhance the activity of α-amylase, regulate the osmotic level and endogenous hormone levels, and improve the salt tolerance of alfalfa seeds. This study demonstrates the efficacy of a simple seed treatment strategy that can improve crop stress resistance, which is of great importance for reducing agricultural costs and promoting sustainable agricultural development.
