“…In Iran, approximately 12.5% of agricultural land is affected by increased or natural salinity [17]. In that country, pistachio (Pistacia vera L.) has been grown commercially for many years and, currently, pistachio plantations encompass about 390 000 ha with annual production of around 150 000 t of pistachio nuts.…”

--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.

“…Saline and alkaline soils cover 204800 km 2 of Iran's area (Aghakhani and Ghorbanli, 1993). Regarding the extension of saline and alkaline soils and the importance of halophytes from the various aspects such as medicinal, industrial and forage, identifying and evaluation the changes of their nutritional value at different growth stages in different habitats can be helpful in planning livestock feed supply in the current critical circumstances (Amiri and Rasouli, 2011).…”

Abstract. Information on forage quality of halophytes in 3 phenological stages could help range managers to determine suitable grazing time to achieve higher animal performance in saline rangelands. Salsola arbuscula Pall. a perennial plant species and resistant to drought and salinity, is distributed in the winter rangelands of the deserts. This plant with Astragalus squarrosus forms a vegetation type in the desert region of Kashan, located in the central region of Iran. To study the forage quality of Salsola arbuscula at three growth stages (vegetative, flowering and seeding), the branches of 10 specimens were randomly sampled with three replications. Then, the samples were dried and milled. Vegetative growth stage is from mid-March to mid-May, flowering is from mid-May to late June and seeding stage starts from early July. Eight forage quality traits including DMD (Dry matter digestibility), WSC (Watersoluble carbohydrate), CP (Crude protein), CF (Crude fiber), ADF (Acid detergent fiber), NDF (Neutral detergent fiber), Ash and ME (Metabolizable energy) were measured. Data were analyzed in a completely randomized design analysis of variance and means were compared by Duncan's test at the 5% level. The results indicated that the forage quality of Salsola arbuscula was affected by phenological stages. The highest percentage of CP and WSC was estimated in the vegetative stage, CF and NDF at flowering stage and DMD, ash and ME in the seeding stage. Due to the high percentage of CP and WSC, the vegetative stage was determined as the best time for forage utilization of Salsola arbuscula.

To evaluate the possibility cultivating Strelitzia Reginae in the regions having inappropriate quality of irrigation water, an factorial experiment (two factors) was conducted in different growth media containing soil and cow manure compost with or without inorganic fertilization under different salinity of irrigation water base on randomized completely block design. The growth medium containing agricultural soil without inorganic fertilization and this bed with inorganic fertilization, cow manure compost amounted 15, 30, and 45% v/v instead of agricultural soil in growth medium; and water salinity of 1, 2, 4, and 6 dS.m -1 , were experiment treatments. Plant growth indices were measured at the end of the 8-month growth period of the plants. The results showed that the increased cow manure compost in the cultivation bed as compared with the application of the inorganic fertilizers, led to the increase of most growth indices of the plant. Moreover, in salinity treatments 1 and 2 dS.m -1 [irrigation water], the measured growth indices showed a relative increase. Generally, adding cow manure compost to cultivation bed of Strelitzia plant can be an appropriate alternative for consumption of inorganic fertilizers and the plant is able to grow with maximum water salinity of 6 dS m -1 .
