Seed germination and seedling growth are the most sensitive plant stages towards salinity. Various techniques can improve emergence and stand formation under salt conditions. Seeds priming is one of the most frequently used technique. Seed priming could develop different defence mechanisms of seeds against salinity stress. This experiment aims to examine the seed priming into potassium nitrate - KNO3 (1%), ascorbic acid – ASA (100mgl-1), and potassium chloride - KCl (1%) solutions, that may reduce harmful effects of salinity stress. Salinity was imposed by treatment of seeds with different concentrations of NaCl (0 (control), 50, 100, 200m MNaCl). All data were analysed statistically by three-way ANOVA. Individual testing of probability was carried out using Tukey’s method p £ 0.05 and p £ 0.01. Correlation dependence was determined using the Pearson correlation coefficient. Test results demonstrated positive effect of seed priming. This was showed by improved soybean seed quality and increased seed germination rate. The intensity of lipid peroxidation, free proline concentration and Na+ was decreased, while K+ in seedlings increased due to priming treatment. Priming of seeds into ASA solution resulted in increased vitamin C concentration, while priming into KNO3 and ÊCl solutions reduced the content of vitamin Ñ in soybean seedlings.

“…Seeds were surface sterilized with 3% solution of sodium hypochlorite, and thereafter soaked in different primers: KNO 3 (1%), KCl (1%), and H 2 O 2 (1%). The duration of priming was 6 h (Miladinov et al 2015). Seeds were removed at the same time, the surplus of water was carefully removed using a paper toweand seeds were dried to 12-14% moisture.…”

The objective of this study was to examine the effect of primers on seed quality parameters using different starting values of germination. For this purpose, ten soybean lines selected at the Institute of Field and Vegetable Crops, Novi Sad were evaluated. The starting values of germination ranged between 48% and 89%. Seeds were surface sterilized with 3% sodium hypochlorite and immersed in different primers: 1% potassium nitrate, 1% potassium chloride and 1% hydrogen peroxide. Untreated seeds were used as the control. The obtained results revealed that the effects of priming depended on soybean line and treatment, whereas the efficiency of this pre-sowing treatment was not affected by the starting value of seed germination. Some lines responded favorably to immersion, while in others priming had an inhibitory effect, causing a significant decrease in germination. There was an increase in germination up to 12% or a decrease up to 11%, depending on line and treatment. Lines that were positively affected by this method also exhibited increased values for other germination parameters: mean germination time (MGT) and time to 50% germination (T50). Lower values of MGT and T50 were observed in lines which showed a negative response to priming and a decrease in germination, but also a more rapid radicle protrusion, as compared to the control.In conclusion, there is no universal applicability of one single primer as it might cause a negative response in some lines and thus reduce seed quality.

“…Upon imbibitions, the embryonic cells switch from quietness to a highly activate metabolic state (Bradford 1986). The positive effects of priming against salt stress have been reported in many crops, such as maize (Tabatabaei 2014), pea (Naz et al 2014) and soybean (Miladinov et al 2015).…”

The potential effect of combined salicylic acid and fish flour to improve plant tolerance to salt stress was investigated. This pre-treatment improved the growth of wheat seedlings under salinity when compared to control (untreated wheat seedlings). Moreover, combined pre-treatment improved significantly phenylalanine ammonia lyase (PAL) and peroxidase (POD) enzyme activities, also phenolic-flavonoid content in the shoots of salt stressed seedlings. One of the most important consequences of increase in salt stress is the oxidative tissue damage. In our study, salt stress increased lipid peroxidation levels (LPO) and also the loss of chlorophylls levels during stress might also be related to photo-oxidation resulting from oxidative stress. Whereas phenylalanine ammonia-lyase (PAL) activities of wheat shoots increased by a 2.1-fold under salt stress, the activities of shoots grown from seeds primed with salicylic acid and fish flour (SA + FF) increased by a 4-fold for 0.05 mM SA + FF, 4.8-fold for 0.1 mM SA + FF and 3.7-fold for 2.5 mM SA + FF combined pre-treatment under salt stress. Also, the combined salicylic acid + fish flour primed seedlings showed higher content of the scopoletin, and salicylic, syringic, vanilic and gallic acids under both salt and nonsalinity stress conditions.
