“…Seed priming methods are the pre-treatment of seeds prior to sowing for the purpose of improving the physiological state of the seeds so that the seed germinates more efficiently [ 9 , 10 ]. There are several seed priming methods practiced in agronomy for increasing the seed germination, crop growth, and yield [ 10 , 11 , 12 , 13 ]. Static magnetic field (SMF) is a seed pre-treatment method based on the interactions of electromagnetic fields with seeds which act as bio-stimulators for the growth of seeds and plants [ 8 , 14 , 15 , 16 ].…”

The combined response of exclusion of solar ultraviolet radiation (UV-A+B and UV-B) and static magnetic field (SMF) pre-treatment of 200 mT for 1 h were studied on soybean (Glycine max) leaves using synchrotron imaging. The seeds of soybean with and without SMF pre-treatment were sown in nursery bags kept in iron meshes where UV-A+B (280–400 nm) and UV-B (280–315 nm) from solar radiation were filtered through a polyester filters. Two controls were planned, one with polythene filter controls (FC)- which allows all the UV (280–400 nm); the other control had no filter used (open control-OC). Midrib regions of the intact third trifoliate leaves were imaged using the phase-contrast imaging technique at BL-4, Indus-2 synchrotron radiation source. The solar UV exclusion results suggest that ambient UV caused a reduction in leaf growth which ultimately reduced the photosynthesis in soybean seedlings, while SMF treatment caused enhancement of leaf growth along with photosynthesis even under the presence of ambient UV-B stress. The width of midrib and second-order veins, length of the second-order veins, leaf vein density, and the density of third-order veins obtained from the quantitative image analysis showed an enhancement in the leaves of plants that emerged from SMF pre-treated seeds as compared to untreated ones grown in open control and filter control conditions (in the presence of ambient UV stress). SMF pre-treated seeds along with UV-A+B and UV-B exclusion also showed significant enhancements in leaf parameters as compared to the UV excluded untreated leaves. Our results suggested that SMF-pretreatment of seeds diminishes the ambient UV-induced adverse effects on soybean.

“…In agriculture, seed vigor is essential for germination and the rapid growth of robust seedlings, leading to satisfactory yields 12 . Diverse types of seed pretreatments employing a limited amount of water (collectively called seed priming) are used to improve the metabolic activity prior to germination, such as osmotic conditioning (hydration followed by drying) and hormone priming 13,14 . The advantages of these treatments include increased emergence, enhanced ability to compete with weeds for resources, better development under stress conditions, improved resistance to pathogens, and increased yields 14 .…”

Nanocarrier systems for the encapsulation of agrochemicals can contribute to sustainable agriculture, but few nanosystems have been developed for plant growth regulators (PGRs). The present study evaluated the effects of seed priming using alginate/chitosan ( nano ALG/CS) and chitosan/tripolyphosphate ( nano CS/TPP) containing GA 3 on the growth and productivity of Solanum lycopersicum cultivated under field conditions. The results demonstrated that nanocarrier systems could improve fruit production, with the productivity increasing almost 4-fold using nano ALG/CS-GA 3 . This pioneering study demonstrates the potential of nanocarrier systems with PGRs for applications in agriculture.

“…In contrast, different concentrations of chitosan seed priming signi cantly affect the germination index and mean germination time but germination percentage (Guan et al, 2009). Root growth characteristics, including taproot and lateral root in the early phase of plant growth, were improved by seed priming (Blunk et al, 2019). Seed priming with 0.2% of Bokashi leachate showed a signi cant improvement in root length (p = 0.0127012), root projection area (p = 0.0173353), root volume (p = 0.039321) and root surface area (p = 0.0173335) compared to others during the early growth (Fig.…”

Basella rubra L. is a type of spinach, which is edible with high nutrient composition. It is also known to be an antioxidant. However, initial germination and root growth remain an issue due to hard exterior seed coating. Thus, some may germinate within 10 to 21 days, and some may not work at all. Inhibited growth may lead to vegetative propagation and micropropagation, which fundamentally reduce the growth and yield. Basella seed treated with Bokashi leachate was found to improve seed germination and root growth. A study was conducted using food waste EM Bokashi leachate (0:1, 1:1500, 1:1000, 1:500) with biopriming duration (6 and 12 hours). The experiment was conducted in a completely random design (CRD) with 3 replications of 100 seeds, with 24 experimental units. Based on the results, a short biopriming duration (6 hours) significantly enhanced the mean germination rate, germination speed accumulated, and coefficient of germination velocity. However, germination percentage had no significant improvement by leachate. Long priming duration significantly reduced the root development due to the seed may loss of desiccation tolerance. The concentration of leachate and priming duration had no significant interaction. In order to improve the germination and root growth performance, 6 hours of seeds priming duration or 1:500 (0.2%) of food waste Bokashi leachate was recommended to soak the Basella rubra seeds.
