Sodium chloride enhances suberization in seminal roots but does not affect cutinized leaf barriers in cultivated and wild barley.

ABSTRACT:

Main conclusion

In the two compared barley genotypes, broader genetic variation did not result in a higher salt tolerance. Instead, specific traits like an exodermis might represent valuable future breeding targets. Soil salinification is a globally increasing phenomenon threatening agricultural yields. In this study, we investigated the physiological reactions of two genotypes of the fourth most abundant cereal crop barley in response to hydroponic sodium chloride exposure. It was of interest to compare a modern cultivar intentionally bred for the highest yields with a wild accession comprising a wider genetic background. Since barley is known to be a relatively salt-tolerant crop, three different sodium concentrations of up to 280 mM have been tested. The physiological adaptation
