“…Over the last few decades, a range of physical, chemical, and biological treatments have been well explored for hydropriming, chemopriming, biopriming, and thermoprining for pre-germinative metabolic modulations in seeds in order to withstand abiotic and biotic stress conditions at germination, seedling growth, and plant development. Various natural and synthetic priming agents (inorganic salts, organic molecules, and natural metabolites) have been reported to boost the antioxidant potential as a stress-responsive strategy for the alleviation of drought-induced damages in germinating seeds (Aranega-Bou et al, 2014;Savvides et al, 2016;Singh et al, 2020). Various studies have reported the applications of salicylic acid, abscisic acid, jasmonic acid, hydrogen peroxide, ascorbic acid, sodium nitroprusside, sodium chloride, sodium glutamate, etc., as wheat seed priming agents to induce tolerance against drought and to mitigate the abovementioned negative impacts (Hameed and Iqbal, 2014;Bhardwaj et al, 2017;Habib et al, 2020).…”

Water-deficit stress negatively affects seed germination, seedling development, and plant growth by disrupting cellular and metabolic functions, reducing the productivity and yield of field crops. In this study, sodium silicate (SS) has been employed as a seed priming agent for acclimation to mild water-deficit stress by invoking priming memory in wheat plants. In pot experiments, the SS-primed (20, 40, and 60 mM) and non-primed control seeds were allowed to grow under normal and mild water-deficit conditions. Subsequently, known methods were followed for physiological and biochemical studies using flag leaves of 98-day mature wheat plants. The antioxidant and hydrolytic enzymes were upregulated, while proteins, reducing sugars, total sugars, and glycine betaine increased significantly in the flag leaves of wheat plants originated from SS-treated seeds compared to the control under mild water-deficit stress. Significant decreases in the malondialdehyde (MDA) and proline contents suggested a controlled production of reactive oxygen species, which resulted in enhanced cell membrane stability. The SS priming induced a significant enhancement in yield, plant biomass, and 100-grain weight of wheat plants under water-deficit stress. The improvement in the yield parameters indicated the induction of Si-mediated stress acclimation in SS-primed seeds that elicited water-deficit tolerance until the maturity of plants, ensuring sustainable productivity of climate-smart plants.

“…Priming promotes germination rate and uniformity due to some kind of metabolic repair of seeds during imbibition, build-up of germination-enhancing metabolites, osmotic adjustment, and a simple reduction in imbibition lag time [1]. The beneficial effects of priming have been observed in several field crops, such as wheat, maize, sugar beet, soybean, sunflower beans, carrot, leek and onion, celery, lettuce, endive, pepper, tomato [1,21,22].…”

Stimulating and increasing of seed field germination, activating the growth of the root system and enhancing productivity is the actual tasks can be solved by priming the seeds of Asparagus officinalis L. The aim of the research was to determine the influence of low-temperature and hydropriming, succinic acid and microelement solution treatment on germination energy, seed germination and quality of planting material of asparagus hybrids. Samples of asparagus hybrids varying by years of reproduction were cooled to temperatures of −70 or −196 °C and heated on air at 22 °C or soaked for 24 h in water in solutions of microelements according to Murashige and Skoog (1–3 mg/L) and/or succinic acid (1–3 mg/L). The use of low-temperature treatments increased seeds germination. Yield study of growing asparagus seedlings obtained from seeds cooled to −70 °C showed a higher number of shoots and roots, their weight compared with the control after 120 days cultivation. Hydropriming of seeds and its further cultivation at optimal temperature conditions promoted significantly higher indices of emergence of asparagus seeds compared to the control values. Treatment of the seeds with microelements and succinic acid did not affect the studied indices after cultivation. It can be concluded that to improve the qualities of asparagus seeds hybrid pretreatment at low temperatures (−70 °C) or hydropriming should be used.

“…Nanopriming agents, such as silver and zinc oxide nanoparticles [87][88][89][90] , have been used to enhance germination indexes and seedling establishment in several plant species: O. sativa 91 , Carthamus tinctorius 92 , Citrullus lanatus 93 , and Thymus kotschyanus 94 . Moreover, nanopriming is one of the most efficient methods to induce salt tolerance capacity in plants by enhancing physiological and biochemical responses 95 .…”

Farmers and seed companies constantly require high-quality seeds with excellent agronomic performance. However, faced with environmental adversity, limited natural resources and increasing food demand around the globe, more attention has turned to improving crop plant production by implementing efficient strategies. Seed priming technology has shown promising biological improvements leading to suitable agronomic performance in crop plants under adverse environmental conditions. Seeds are subjected to controlled conditions that are conducive to complex physiological, biochemical, and molecular changes, conferring specific stress tolerance to subsequent germination and growth conditions. In this review paper, we aimed to study the recent approaches in the efficiency of hydropriming, osmopriming, chemopriming, hormopriming, nanopriming, matrix priming, biopriming, physical priming and hybrid priming procedures in the production of crop plants under environmental adversity, as well as their biological mechanism changes. All priming methods demonstrated relevant changes in the biological mechanism related to crop plant production by mitigating salinity effects, heavy metals, and flooding stress and enhancing chilling, heat, drought and phytopathogen tolerance. We strongly recommend that researchers combine multiple priming methods, known as hybrid priming, in their investigations to provide novel technologies and additional biological approaches to enhance the knowledge of crop plant science. Thus, the findings shed light on the use of seed priming technology as a key strategy to increase crop plant production under environmental adversity by acquiring stress tolerance and enhancing agronomic traits to meet the global food demand.
