THE RESPONSE OF FOLIAR PROTEINS IN TWO WHEAT (TRITICUM AESTIVUM) CULTIVARS TO SALT STRESS

Abstract

Effect of various NaCl treatments (0, 50, 100, 200, and 300 mM) at different growth and development stages (tillering, boot swellen, flowering and anthesis) in two wheat cultivars (Ghods: salt – sensitive, Boolani: salt – resistant) on SDS-PAGE electrophoretic pattern of leaf proteins was studied under greenhouse conditions. Generally, in response to salinity treatments, the decrease in protein synthesis in Ghods was more than that of Boolani and the increase of protein bands in Boolani was more than that of Ghods. Therefore, it seemed that Boolani had more ability in maintaining its leaf proteins in response to salt. Thus, from biochemical point of view, Boolani was introduced as a cultivar with more resistance to salinity stress.
