### Effect of Magnetoriming on Phytohormones (ABA, GA and IAA) under Salt Stress  
The results of hormones, NO and superoxide content as well as enzyme activities are presented as the relative change in magnetoprimed over unprimed seeds under different modulators in non-saline and saline environments. Magnetopriming decreased the ABA content in germinating seeds as compared to unprimed ones in non-saline and saline conditions (Figure 3A). On the other hand, GA significantly increased in magnetoprimed seeds under both the experimental conditions; the percentage of increase being more in saline (376%) than non-saline (136%) conditions (Figure 3B). Also, ABA/GA ratio was lower in seedlings from magnetoprimed seeds in both the non-saline (93%) and saline (98%) conditions as compared to the unprimed seeds (Figure 3C). The donor of NO decreased, and inhibitors of NO and ROS increased, the magnetoprimed-induced ABA/GA content in both the conditions as compared to their respective controls (Figure 3C). The relative increase was significantly high (168 to 349%) with NR and ROS inhibitors under non-saline conditions, whereas it was within a range of 41-128% under saline conditions. Figure 3: _Cont._Figure 3: Relative change (%) in ABA (**A**), GA (**B**), ABA/GA (**C**), IAA (**D**) and IAA/GA (**E**) of magnetometer over unprimed seeds kept for 24 h in different modulators of NO and ROS production under  
non-saline and saline conditions. The data are represented as mean values of relative change \(\pm\) SE (n = 3). ###\(p\) < 0.001, ###\(p\) < 0.01, #\(p\) < 0.05 shows significant difference amongst the relative change in the seeds grown in control with the seeds grown in different modulators of NO/ROS production under non-saline conditions; ***\(p\) < 0.001, **\(p\) < 0.01, *\(p\) < 0.05 shows significant difference amongst the relative change in the seeds grown in control with the seeds grown in different modulators of NO/ROS production under saline conditions. The trend of IAA content under various treatments was similar to that of GA in the germinating seeds. There was an increase of 64% and 85% in magnetoprimed seeds over unprimed seeds in non-saline and saline environments, respectively (Figure 3D). Similarly, SNP (NO donor) also caused a significantly higher percentage of enhancement in IAA content of magnetoprimed seeds, though the extent of promotion (93%) was higher under saline conditions compared to a non-saline medium (55%) (Figure 3D). The inhibitors ST, L-NAME and DPI caused a reduction in magnetoprimed induced IAA content under both the conditions as compared to their respective controls (Figure 3D). Further, we have also observed that IAA/GA ratio was remarkably decreased by magnetopriming in non-saline (30%) and saline (61%) conditions with respect to the unprimed ones (Figure 3E); SNP treatment caused 37% and 46% reduction in IAA/GA ratio in seedlings from magnetoprimed seeds under non-saline and saline conditions, respectively, as compared to the unprimed ones. The IAA/GA ratio was also significantly reduced by magnetopriming in ST, L-NAME and DPI treatments under salt stress, but the extent of reduction was lesser than control and SNP treatment (Figure 3E). Effect of Magnetoriming on Superoxide (\(O_{2}\)\({}^{\bullet-}\)), Nitric Oxide (NO) Content, NOS-like and NR Activities under Salt Stress  
The \(O_{2}\)\({}^{\bullet-}\) and NO content and the activities of NOS-like and NR in the 24 h soaked seeds were significantly increased in magnetoprimed seeds under non-saline condition (Figures 4 and 5). The addition of SNP during imbibition resulted in a significant reduction in all observations compared to their respective controls in non-saline environment. However, under salinity the response obtained differed, as a significant increase in NO content was observed by SNP as compared to the control. The inhibitors ST, L-NAME and DPI also showed a significant percentage of reduction in relative values when compared with their controls (Figures 4 and 5A,B).
