Calcium induces salinity tolerance in pistachio rootstocks. Abstract – – 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 solu-tions amended with (50, 100 and 150) mM CaSO4. Seeds were planted in pots containing a mixture of gar-den soil, sand and compost (1/3 v/v) to investigate the effect of calcium sulphate on plants grown unde
