A Study on the Priming Effect of Salt Solution onthe Hulless Barley Seeds

PurposeTo determine the effect of salt solution on the seed priming.

MethodSix of hulless barley lines were selected in this study. The seeds were soaked in salt solution which mass concentration were 0 (CK), 0.025, 0.050, 0.075 and 0.100 g/mL in 1, 2, 3, 4, 5 and 6 h, respectively. And then the germination characteristics of hulless barley seeds were determined and the priming effect of salt solution on the seeds of hulless barley was studied by using the standard germination test after washed out the seeds.

ResultThe salt solution had obvious priming effect on the highland barley seeds. With the increase of salt solution mass concentration and the soaking time, the germination characteristics of hulless barley seeds improved gradually at first, and then deteriorated gradually.

ConclusionComprehensive analysis results show that the priming effect of 0.025 g/mL salt solution soaking for 3 h was the best, the seeds of hulless barley germinated rapidly and neatly, and grew into strong seedlings, which could be applied in the practice of hulless barley sowing and could be the foundation of high yield planting on hulless barley. This method can be used to improve the field emergence rate and uniformity and to ensure complete seedling emergence in hulless barley seed sowing practice.
