“…The interplay of NPs in plant systems depends on species, seed age, experimental temperature, exposure method, duration, and, more importantly, the size and concentrations of nanoparticles. The germination and seedling vigor are boosted with different bio-capped NP priming methods. , Several metal-based NPs and carbon-based NPs have increased the quality of seed properties related to structural, functional, and molecular alterations in recent years. , When a seed is infused with NPs or nanoparticles, the metabolic process is triggered, resulting in increased germination, seedling vigor, and plant growth. Numerous studies demonstrated that seed priming with metal and metal oxide NPs could enhance biochemical and molecular traits such as improved enzymatic hydrolysis, food material metabolism, hormone actions, antioxidant capabilities, chromosomal stability, and cell growth. , The seed yield was increased by ZnO NPs and Zn 2+ compounds on different dosages from 160 mg Zn/kg to 400 mg Zn/kg, inducing the least oxidative stress.…”

Bare and stabilized zinc oxide nanoparticles (ZnO NPs) were prepared by a microwave-assisted method and used as a priming agent to improve the morphological, physiological, and biochemical quality of Vigna radiata. The priming action was made under normal and moisture stress conditions. A microwave reactor of 850 watts power was used to heat 30 mL of a nanocolloidal solution at 140 °C for 20 min. The stable spherical ZnO NPs at 50.4 mV with 28.2 nm particle size were generated and capped with different biomolecules, cysteine and PVA, to get biostabilized ZnO NPs at 48.8 and 108.5 nm with ζ potentials of −56.2 and −52.0 mV, respectively, holding distinct morphology. The nanopriming effect was studied in V. radiata seeds for bare ZnO and capped ZnO NPs under normal and moisture stress environments. Cysteine-capped ZnO NPs at 250 ppm showed improved germination (90 and 76%), radicle growth (7.6 and 3.6 cm), seedling Vigor (3064 and 1816), dry matter production (145.06 and 96.92 mg/25 seedlings), and hydrolytic (α-amylase and protease) and antioxidant (peroxidase and superoxide dismutase) enzyme activity under normal and moisture stress conditions. The improved priming action of cysteine-capped ZnO NPs is due to increased cell elongation and cell division in the radicle. The uptake and translocation of ZnO NPs in the V. radiata root are evidenced by the presence of an 11.4 ppm zinc level, which was also supported by EDAX and FITC labeling results.

“…There is a singular report on the usage of Ag‐doped calcium hydroxide for MB dye removal from wastewater [16] . The aforesaid literature survey clearly points out that the systematic studies on how a change of molarity of chemical reactants in the chemical precipitation process of calcium hydroxide affects the physical and especially, the wastewater treatment efficacy are far from well‐studied [1–21] . This gap of information in literature creates the scope of this study.…”

“…Calcium hydroxide is extensively used in several applications e. g., Portland cement production, [1,2] cultural heritage conservations, [3,4] and vaterite blocks fabrication, [5] which is important for advanced bio applications. Similarly, a very important emerging area of research is its utilization for nano‐priming action on seed embryos e. g., Indian Gram seeds [6] . Rigorous efforts are currently underway to extend the inherent biocompatibility and antibacterial capacities of Ca(OH) 2 for a wide variety of applications such as intercanal medication for postoperative pain in root canal therapy, [7] advanced bone restoration, [8] endodontics, [9] and antimicrobial activity [10] .…”

With the increase in demand of textiles products, the polluted groundwater problem in the world is increasing proportionally and leading to environmental and health problems. Hence in this present work, we report on the dye removal efficacy of nano Ca(OH) 2 by changing the molarity of the reactants. In the process, the chemical precipitation technique is used to synthesize the phase pure nano Ca(OH) 2 powders using equimolar concentrations (e. g., 0.4 M, 0.6 M, 0.8 M and 1 M) of [Ca(NO 3 ) 2 ⋅ 4H 2 O] and NaOH solutions. The prepared material was characterized using XRD, FTIR, and UV-Vis spectroscopy. The results from the characterization study show, that the dye removal behaviour is complex and is sensitive to a simultaneous combination of many factors e. g., the molarities of the reactants, the resultant nanocrystallite size, band gap energy, the concentration of the dye and, the temperature of adsorption. Therefore, these results are discussed in terms of relative variations in the microstructure, lattice strain, band gap energy, defect structure, and the amount of (OH À ) ions. Further, the probable mechanism of dye removal behaviour is suggested. Finally, the consequences of these results in terms of microstructurally tuned nano Ca(OH) 2 materials development for prospective futuristic applications are highlighted.

“…Seed extracts from Cassia angustifolia , rich in galactomannan and other biomolecules, enabled their terminal oxygen and hydroxide groups to bind Ca and Se ions. The porous Se-(Ca(OH) 2 ) nanocomposite showed high efficacy in interacting with seed embryos and stimulating germination (Antony et al 2022 ). Nano-scale zero-valent iron (G-nZVI), synthesized using fruit peel waste of Punica granatum L., could increase the germination percentage and seedling vigour of rice (Guha et al 2021 ).…”

Key message The potential of seed priming is still not fully exploited. Our limited knowledge of the molecular dynamics of seed pre-germinative metabolism is the main hindrance to more effective new-generation techniques. Abstract Climate change and other recent global crises are disrupting food security. To cope with the current demand for increased food, feed, and biofuel production, while preserving sustainability, continuous technological innovation should be provided to the agri-food sector. Seed priming, a pre-sowing technique used to increase seed vigor, has become a valuable tool due to its potential to enhance germination and stress resilience under changing environments. Successful priming protocols result from the ability to properly act on the seed pre-germinative metabolism and stimulate events that are crucial for seed quality. However, the technique still requires constant optimization, and researchers are committed to addressing some key open questions to overcome such drawbacks. In this review, an update of the current scientific and technical knowledge related to seed priming is provided. The rehydration–dehydration cycle associated with priming treatments can be described in terms of metabolic pathways that are triggered, modulated, or turned off, depending on the seed physiological stage. Understanding the ways seed priming affects, either positively or negatively, such metabolic pathways and impacts gene expression and protein/metabolite accumulation/depletion represents an essential step toward the identification of novel seed quality hallmarks. The need to expand the basic knowledge on the molecular mechanisms ruling the seed response to priming is underlined along with the strong potential of applied research on primed seeds as a source of seed quality hallmarks. This route will hasten the implementation of seed priming techniques needed to support sustainable agriculture systems.
