| Abstract: | A salt tolerance experiment was performed to study the effect of the GPert mutation in different genetic backgrounds of spring barley, Hordeum vulgare. L. Twenty-one lines carrying GPert along with 20 related non-GPert lines were grown for 4 weeks in low salt (25 mol m?3 NaCI) and salt stress (175 mol m?3 NaCI) hydroponic cultures. Shoot Na+ content was taken as a measure of salt tolerance. Salt tolerance of the two groups (GPert versus non-GPert) was compared, as was the performance of individual GPert lines with their non-GPert parental lines. The results show that GPert has a general positive effect on salt tolerance in reducing shoot Na+ content, but that this is regulated by genetic background. |
