Monitoring the Comparative Effects of Hydropriming and Halopriming on Germination Performance of Secale montanum Guss. Under Salinity Stress

Seed priming is known as method which improves germination performance in seeds, under stress conditions. The objective of this study was to compare the effectiveness of Hydropriming and Halopriming on germination performance of Secale montanum growing under the NaCl-salinity stress. For the Halopriming treatments, Concentrations of 125, 250 and 500 mM of sodium chloride was applied. This experiment was carried out in the four levels of salinity stress. Germination percentage in Halopriming showed the significant reduction with increasing durations and concentrations of treatments. Longer root and shoot length of S. mountanum was observed in Hydropriming treatment. S. montanum appears to be moderately salt-tolerant. The results of this study indicated that Halopriming and Hydropriming had negative effects on germination and growth of S. montanum. From the present study, it can be concluded that seeds of S. montanum are sensitive to priming techniques.
