“…The present study revealed that primed seeds (HA and HP primed for 3 h and 5 h) had reduced amount of MDA content compared with non-primed seeds believed to be attributed to minimization of oxidative damage by improved antioxidant mechanisms and repairing of the membrane damage. In agreement with [38,42], results of EC value with MDA content of this study also confirmed significant positive correlation (0.54 **).…”

“…[15] reported that seed priming enhanced antioxidant defense mechanism of aged seed and consequently reduced cell membrane damage caused by the accumulation of ROS due to lipid peroxidation. This is similar to the findings of [38], in which different priming methods were able to reduce the rate of electrolyte leakage and thereby increased the membrane stability in rice. The results of this study showed that the lowest EC value was recorded in seeds primed for 3 to 5 h (103.4-109.4 µS cm −1 g −1 ), and it was 48-51% reduction compared with non-primed seeds.…”

“…The weakening of antioxidant defense mechanism resulted in low seed and seedling quality performance [2,39]. Several studies suggested that priming triggers the ROS scavenging process by increasing antioxidant (SOD, CAT, POD and APX) activities and enhanced stress bearing ability of the seedling [11], [38,40]. In the present study, we observed that priming with HA increased the POD activities compared with non-primed seeds and the highest POD activity (49.6 nmol/min/mg FW) was recorded in HA priming for 5 h with 50% increment compared with non-primed seeds.…”

Soybean seed vigour declines with increase in storage duration, due to ageing, which can be alleviated through seed priming. The objective of this study was to investigate the effects of Humic acid (HA) priming on germination, vigour and seedling performance under laboratory and greenhouse conditions with two soil moisture level [50% and 80% field capacity (FC)]. Seeds stored for 12 months having 60% germination were primed either with 0.2 g/L HA solution or distilled water (hydro-primed) at 25 °C for 1, 3, 5 and 7 h. Non-primed dry seeds were used as control, giving nine treatment combinations. Various germination traits [mean germination time (MGT), final germination percentage (FG%), germination rate index (GRI), seedling emergence percentage (SEP)], mean emergence time (MET), seedling quality traits [seedling vigor index (SVI), shoot length, root length, root volume], antioxidant enzyme activities [catalase (CAT), peroxidase (POD)], lipid peroxidation [malondialdehyde (MDA)] and electrical conductivity (EC) were determined. A germination test in the laboratory was conducted as single factor (nine priming treatments), while the greenhouse experiment was conducted as two factors [2 soil moisture level (50 and 80% FC) and 9 priming treatments]. The results indicated that seeds primed with HA for 5 h was able to reinstate the CAT activities (25%), POD activities (50%) and reduced EC (51%) and MDA content (40%) compared with non-primed seeds, reduced the MET (from 4.3 to 3.5 days), increased FG% (from 62% to 71%), GRI (15.6–21.1) and SEP (from 35% to 54%) and (from 60% to 72%) at 50% FC level and 80% FC level, respectively. A strong negative correlation (r = −0.80 **) was found between MDA content and GRI, while CAT and POD activities had positive correlation with GRI r= 0.67 ** and r = 0.56 **, respectively. Thus, priming with 0.2 g/L HA for 5 h improved the vigour of minimally deteriorated soybean seeds resulting in increased emergence with more uniform field establishment.

“…Pre-sowing seed treatments range from hydropriming, chemical, and biological to physical ones [1]. Improved seed performance in the field has been observed in response to these priming agents in terms of improved germination rate, metabolic pool, and stress-tolerance amongst all halopriming being comparatively easy to manage by a farmer is practiced more than other strategies [2,3].…”

Zinc is an essential element for plant growth and development as it plays an important role in various metabolic processes with nutritional enrichment. The treatment with zinc sulfate is also economic. Momordica charantia is an economically important medicinal plant reported for a range of pharmaceutical and pharmacological properties. In this study, nutripriming with zinc sulfate (0.1%, 0.2%, and 0.3% solution) was applied to M. charantia seeds to optimize better dose. Based upon seedling establishment, 0.3% zinc sulfate was selected for final field experiment with randomized complete block design (RCBD) with five replications. Improved germination percentage, vigor, total soluble sugars, chlorophyll-a, chlorophyll-b, total chlorophyll content, and peroxidase activity were observed variably in leaves, fruit, and peel. Other nutritive components showed maintenance in fruits of treated plants indicating that the treatment did not cause any nutritive loss. Antimicrobial activity of leaves (in terms of the minimum inhibitory concentration) against Staphylococcus aureus and Pseudomonas aeruginosa was positively correlated with sinapic acid, vanillic acid, cinnamic acid, syringic acid, chlorogenic acid, benzoic acid, and ferulic acid. It has been concluded from this study that seed priming with zinc sulfate can improve seedling establishment, photosynthetic pigments, and stable nutritive value. Therefore, zinc from zinc sulfate priming has been proved as a beneficial fertilizer for M. charantia plant growth, yield, and nutraceutical potential.

“…Then, seeds are separated from the matrix and dried to near the initial moisture level. The procedure is flexible (by mixing with other materials), cost-effective, and able to treat a large number of seeds 100 . Important enhancement in crop production has been noted in many reports for the use of MP under environmental stress, such as drought 23 , salinity 101 , and low temperature 102 .…”

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.
