Germination and Emergence of Several Varieties of Barley in Salinized Soil Cultures¹

Salt tolerance of barley (Hordeum vulgare L.) cultivars at the germination stage: Analysis of the response functions

“…If the threshold salinity EC t is taken as the reference parameter, some cultivars, such as 'Mari', 'Viva' or 'Kim', are about three times as tolerant as 'Barbarrosa', 'Koru' or 'Igri'. Previous studies have also noted this fact (Ayers, 1953;Donovan, 1979;Schaller et al, 1981;Srivastava and Jana, 1984), although the variability range of our cultivars seems to be slightly higher.…”

“…One of them is the search for plant germplasm with a high relative salt tolerance (Shannon, 1984). Barley is known to be one of the most salt-tolerant crops (Maas and Hoffman, 1977;Shannon, 1984), having a high level of variability in tolerance among cultivars (Ayers, 1953;Donovan and Day, 1969;Schaller et al, 1981;Srivastava and Jana, 1984).…”

Comprehensive screening and selection of okra (Abelmoschus esculentus) germplasm for salinity tolerance at the seedling stage and during plant ontogeny

“…Thus, the different genotypes responded differently under increasing NaCl concentrations. The depressed growth of genotypes may be ascribed to the toxic effect of NaCl and low water potential in the rooting medium (Ayers, 1953).…”

Evaluation of Rice (<i>Oryza sativa</i> L.) Genotypes at Germination and Early Seedling Stage for Their Tolerance to Salinity

“…Rice is generally sensitive to salinity (Yeo et al, 1991) though rice varieties differ greatly in salt tolerance (Akbar et al, 1997;Amin et al, 1996;Yeo et al, 1991). Salinity may affect seed germination in two ways: (a) osmotically, by decreasing the ease with which seeds may take up water; and (b) ionically, by facilitating the uptake of ions in excess amount to be toxic for the embryonic activity (Ayers, 1953). For many plants, salt stress is more inhibitor during seed germination than at any other stage of growth (Bewley and Black, 1982).…”
