“…Some researchers have reported that there is a negative relationship between salt tolerance and Na in plant shoots in some plant species [44,45]; moreover, the salt-tolerant plants generally exclude Na from their shoots to prevent Na accumulation in the leaves [46]. The plant materials used in our experiment showed an inverse relationship between salt tolerance and Na concentration in leaves.…”

--Introduction. Saline soils may exert a different effect on seed germination and seedling growth. Materials and methods. The seeds of two rootstocks of pistachio (Pistacia vera), Ghazvini and Badami-e-zarand, were incubated at 20°C in the dark in a 150 mM NaCl solution or in 150 mM NaCl solutions amended with (50, 100 and 150) mM CaSO 4 . Seeds were planted in pots containing a mixture of garden soil, sand and compost (1/3 v/v) to investigate the effect of calcium sulphate on plants grown under salt stress. Irrigation water treatments were control (deionised water alone); salinity stress (150 mM NaCl); salinity with 50 mM CaSO 4 ; salinity with 100 mM CaSO 4 ; and salinity with 150 mM CaSO 4 . Results and discussion. In all treatments, both the final germination percentage and the final percentage of seeds with emerging seedlings longer than 20 mm were higher in the Ghazvini rootstock than in the Badami-e-zarand rootstock. Both the final germination percentage and the final percentage of seeds with emerging seedlings were significantly increased with increasing CaSO 4 concentration, except at the highest CaSO 4 concentration. The plants grown under 150 mM NaCl produced less dry matter and had lower chlorophyll content than those grown without NaCl. Supplementary CaSO 4 only at (50 and 100) mM concentrations ameliorated the negative effects of salinity on plant dry matter and chlorophyll content. Sodium (Na) concentration in plant tissues increased in both leaves and roots of plants under the NaCl treatment alone. The Ghazvini rootstock had much lower Na. Additions of CaSO 4 significantly lowered the concentration of Na in both leaves and roots. The Ghazvini rootstock was more tolerant to salinity than the Badami-e-zarand rootstock. The accumulation of Na in leaves and roots indicates a possible mechanism whereby cv. Ghazvini copes with salinity in the rooting medium, and/or may indicate the existence of an inhibition mechanism of Na transport to leaves. Concentrations of Ca and K were lower in the plants grown at high NaCl concentration than in those under the control treatment, and, for the cv. Ghazvini, these two element's concentrations were increased in both leaves and roots for the plants with calcium sulphate treatment; for the cv. Badamie-zarand, these concentrations were increased in only the roots.Iran Islamic Republic / Pistacia vera / germination / growth / osmotic stress / saline water / calcium sulphate / salt tolerance Le calcium induit une tolérance au sel dans les porte-greffes de pistachiers.Résumé --Introduction.

“…Reductions in total dry matter were much lower in Pixy than in either Myrobolan B or Marianna GF 8-1 under S treatment compared with C treatment. Some researchers have reported that there is a negative relationship between salt tolerance and Na in plant shoots in some plant species (Gorham et al, 1985;Hampson and Simpson, 1990); moreover, the salt-tolerant plants generally exclude Na from their shoots to prevent Na accumulation in the leaves (Ashraf, 1994).

Three vegetative rootstocks of plum (Prunus domestica), Marianna GF 8-1 (Prunus cerasifera × munsoniana), Myrobolan B (P. Cerasifera) and Pixy (P. Insititia) were grown in pots containing sand and irrigated with complete nutrient solution to investigate the effect of calcium sulfate supplied to the nutrient solution on plants grown under salt stress. Treatments were (1) control (C): nutrient solution alone; (2) S (salinity stress): 40 mM NaCl; (3) S+Ca1: 40 mM NaCl +2.5 mM calcium (Ca) and (4) S+Ca 2 : 40 mM NaCl + 5 mM Ca. Calcium was supplied as CaSO 4 . The plants grown under 40 mol L −1 NaCl produced less dry matter and had lower chlorophyll content than those without NaCl. Supplementary CaSO 4 at both 2.5 and 5 mM concentrations ameliorated the negative effects of salinity on plant dry matter and chlorophyll content. Salt treatment impaired membrane permeability by increasing electrolyte leakage. The addition of calcium sulfate partially maintained membrane permeability. Sodium (Na) concentration in plant tissues increased in both leaves and roots of plants under the high NaCl treatment. Pixy had much lower Na. The CaSO 4 treatments lowered significantly the concentrations of Na in both leaves and roots. Pixy was more tolerant to salinity than the other two rootstocks. The accumulation of Na in leaves and roots indicates a possible mechanism whereby Pixy copes with salinity in the rooting medium, and/or may indicate the existence of an inhibition mechanism of Na transport to leaves. Concentrations of Ca and K were lower in the plants grown at high NaCl than in those under the control treatment, and these two element concentrations were increased by calcium sulfate treatments in both leaves and roots, but remained lower than control values in most cases.

“…High Na''^ content of the growth medium is known to have an antagonistic effect on K'û ptake in plants (LAUCHLI and EPSTEIN 1970, JACOBY and RATNER 1974, FLOWERS et al 1977, GREENWAY and MUNNS 1980, JESCHKE 1984, ASHRAF 1994. In addition, the adverse effects of sodium or chloride on membrane stability or a preferential sequestration of sodium in vacuoles, can result in low K' ' uptake in plants (jESCHKE 1977).…”

The degree of salt tolerance of two newly developed genotypes of spring wheat, S24 and S36 was assessed with respect to their parents, LU26S (from Pakistan) and Kharchia (from India). These four lines along with a salt‐tolerant genotype SARC‐1 and two salt‐sensitive cvs Potohar and Yecora Rojo were subjected to salinized sand culture containing 0, 125 or 250 mol m−3 NaCl in full strength Hoagland's nutrient solution. S24 produced significantly greater grain yield and had greater 1000 seed weight and number of tillers per plant than those of the other cultivars /lines. S36 was not significantly different from its parents in seed yield and yield components. SARC‐1 was the second highest in grain yield of all cultivars/lines, but it did not differ significantly from LU26S and Kharchia in 1000 seed weight and number of tillers per plant. The greater degree of salt tolerance of S24 could be related to its lower accumulation of Na+ in the leaves and maintenance of higher leaf K/Na ratios and K versus Na selectivity as compared to its parents. S36, which was as good as its parents in growth, also had lower Na+ and higher K/Na ratios and K versus Na selectivity in the leaves at the highest salt level than those in its parents. SARC‐1 did not differ from LU26S and Kharchia in ionic content or K/Na ratios and K versus Na selectivities of both leaves and roots. Both the salt‐sensitive cultivars, Potohar and Yecora Rojo, had significantly greater leaf Na+ and Cl− concentrations and lower leaf K/Na ratios and K versus Na selectivities than all the salt‐tolerant lines examined in this study. From this study it is evident that improvement in salt tolerance of spring wheat is possible through selection and breeding, and pattern of ion accumulation is not consistent among the salt‐tolerant genotypes in relation to their degree of salt tolerance.
