Genotypic differences in root and shoot growth of barley (Hordeum vulgare L.) grown under different salinity levels.

In water-limited areas of Tunisia, more than 30% of subsurface water used for irrigation is saline water, leading to a long-term salinization and degradation processes. To prevent the problems and to minimize the negative impact of using saline water, selection of proper germplasm as well as integrated soil and water management are essential. Understanding the diversity for salt tolerance in barley (Hordeum vulgare L.
