Abstract
Recurrent selection of sunflower hypocotyl calluses maintained at different levels of salinity improved the tolerance capacity. At loth sub-culture, the selected Ussues of cvs - EC 68415 and Modern, showed better growth at the highest (- I.368 MPa) salinity. Growth, turgor, and accumulation of solutes and ions were greater in these tissues. However, the involvement of turgor and proline in salt tolerance seems to be doubtful. The increase in sodium chloride rn the medium enhanced the uptake of sodium and potassium, leading to maintenance of a greater K/Na raûo in selected tissues, thereby suggesting a role for ionic equilibrium between potassium and sodium.
Keywords: Recurrent selection, sunflower, salt stress, water relation, hypocotyl callus
