“…JS‐335) seeds were obtained from the ICAR‐Indian Institute of Soybean Research, Khandwa Road, Indore, M.P., India. We have selected soybean variety JS‐335 for the present study since it is salt sensitive and it gives best response after SMF pre‐treatment under salt stress (Kataria et al ,b, ).…”

“…A direct current (DC) power supply (80 V/10 A) with continuous variable output was used. The SMF strength was achieved via altering the current in the coils of the electromagnet, 200 mT for 1 h of SMF treatment was given to soybean seeds, which is based on earlier studies (Shine et al , Kataria et al ). The probe is attached to the digital gauss meter ( AETech model DGM‐102), which was used for quantification of the SMF strength produced between the poles, variations of 1.2% in vertical and 0.4% in horizontal direction of the applied field were noted.…”

“…Magnetopriming with static magnetic field (SMF) increases seed germination (Kataria et al , Shine et al , Kataria and Jain ), speed of germination (Anand et al ), plant development (Kataria et al ,b, ), length and mass of the root and shoot (Vashisth and Nagarajan , Shine et al ), vigor indices (Kataria et al , Shine et al ), photosynthetic performance (Shine et al , Baghel et al ) and ultimately yield of plants (Kataria and Jain , Kataria et al ). During germination, seeds priming with SMF enhanced the content of reactive oxygen species (ROS) and enzyme activities such as α‐amylase, protease and nitrate reductase in wheat, sunflower, soybean and maize (Bhatnagar and Deb , Kataria et al , Baghel et al , Anand et al ). ROS like O 2 •− and H 2 O 2 may take part as a key signaling molecules in accomplishment of seed germination or release of seed dormancy (Sarath et al , Anand et al ).…”

“…Plants are commonly more susceptible to salt stress throughout germination and early growth of seedlings. Salt stress is accountable for delayed or decreased germination and vigor of soybean seedlings (Kataria et al , Kataria and Jain ). Sufficient literature is available regarding magnetopriming‐induced alleviation of salt, drought and UV‐B stress in plants (Kataria et al ,b, , Kataria and Jain ).…”

In the present study, experiments were performed to investigate the role of nitric oxide (NO) in magnetopriming-induced seed germination and early growth characteristics of soybean (Glycine max) seedlings under salt stress. The NO donor (sodium nitroprusside, SNP), NO scavenger (2-[4-carboxyphenyl]-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, CPTIO), inhibitors of nitrate reductase (sodium tungstate, ST) or NO synthase (N-nitro-L-Arg-methyl ester, LNAME) and NADPH oxidase inhibitor (diphenylene iodonium, DPI) have been used to measure the role of NO in the alleviation of salinity stress by static magnetic field (SMF of 200 mT, 1 h). Salt stress (50 mM NaCl) significantly reduced germination and early growth of seedlings emerged from non-primed seeds. Pre-treatment of seeds with SMF positively stimulated the germination and consequently promoted the seedling growth. ST, LNAME, CPTIO and DPI significantly decreased the growth of seedling, activities of -amylase, protease and nitrate reductase (NR), hydrogen peroxide (H 2 O 2 ), superoxide (O 2•− ) and NO content in roots of seedlings emerged from non-primed and SMF-primed seeds. However, the extent of reduction was higher with ST in seedlings of SMF-primed seeds under both conditions, whereas SNP promoted all the studied parameters. Moreover, the generation of NO was also confirmed microscopically using a membrane permanent fluorochrome (4-5-diaminofluorescein diacetate [DAF-2 DA]). Further, analysis showed that SMF enhanced the NR activity and triggered the NO production and NR was maximally decreased by ST as compared to LNAME, CPTIO and DPI. Thus, in addition to ROS, NO might be one of the important signaling molecules in magnetopriming-induced salt tolerance in soybean and NR may be responsible for SMF-triggered NO generation in roots of soybean.

Different priming methods were developed to improve seed germination and the early growth of seedlings. This study aimed to examine the combined effect of bacterial inoculation and static magnetic field on white mustard (Sinapis alba L.) germination. A plant growth-promoting bacterial strain Bacillus amyloliquefaciens D5 ARV was used for biopriming. The static magnetic field of 90 mT was applied for 5 and 15 min. Analyses of abscisic acid, chlorophyll, anthocyanins, flavonoids content, nitrogen balance index, and bacterial indole-3-acetic acid were used to explain observed effects. Bacterial inoculation improved seed germination, whereas exposure to 90 mT for 15 min suppressed germination. Such an unfavorable effect was neutralized when the treatment with the static magnetic field was combined with bacterial inoculation. The highest germination percentage was a result of synergistic action of B. amyloliquefaciens D5 ARV and 15 min long exposure to 90 mT, which induced an increase of 53.20% in the number of germinated seeds. The static magnetic field induced the increase of bacterial indole-3acetic acid production threefold times. Biomagnetic priming caused a metabolic shift from primary to secondary metabolism in the white mustard seedlings. An adequate combination of biological priming and static magnetic field treatment can be successfully used in old seed revitalization and germination improvements.
