Abstract
Effect of sodium chloride on callus development in hypocotyl explants and seed germnation in two c.v. Morden and EC 68415 of sunflower was studied. Better callus development and germination were noticed in the former. Pattern of changes in water relations and accumulation of reducing sugars, soluble amino acids and proline were also studied in germinated seeds and calli. These studies indicated that turgor can not be related to salt tolerance. Proline accumulation seems more due to the effect of salinity. In the light of inconsistencies noticed in water relations and solute contents wiih respect to germination and seedling vigour, role of any one of these in greater salt tolerance of c.v. EC 68415 is not beyond doubt. Since better callus dwelopment and seed germination and vigour are associated, the former could be a more reliable index of salt tolerance in the two cultivars.
