Abstract
Growth and development of plants is adversely affected by ionic and osmotic stresses in the saline soil. Although barley (Hordeum vulgare) is regarded as relatively tolerant to salt stress among the Tririceae, modern barley cultivars suffer severely at salt concentrations encountered in the field constructed in reclaimed tidelands. This study was conducted to elucidate salt tolerance mechanisms of a collection from Tunisia (Tunisia 76; T76) at the germination and early seedling stages. Gwandongpi 41 (G41) was used as a salt-susceptible control variety. Germination was examined in a culture solution containing 0
