Effect of Salt Stress on Germination of Wheat and Screening of Salt Tolerance Indices

doi:10.7668/hbnxb.2014.04.031

Abstract

Abstract: In this study,11 winter wheat species were selected to explore the differences of eight trait indicators under different concentrations of NaCl solution,which was chosen as the salt stress.And the relative values of the indicators were analyzed by the analysis of the outstanding difference.The results showed that as the concentration of NaCl salt solution increases the relative salt tolerance coefficient of each index of the winter wheat decreased during the germination.In addition,there were significant differences among the germination rate,germination potential,root length,coleoptile length,seedling height,and the growth rate of the first leaf as well as the fresh weight of seedlings between different species and different concentrations.But the effect of NaCl salt solution on the number of the wheat roots was not significant.So the seven indexes of physiological traits can be used as an effective indicator of the selection of winter wheat during the germination indoor.The study also indicated that the tested varieties of Dekang 961 and Qingmai 6 exhibit stronger salt tolerance during the germination stage.

Key words: Winter wheat, Germination stage, Salt stress, Salt tolerance, Salt tolerance indices
