English abstract The objective of this experiment was to determine the influence of different salt levels (zero, 15, 30, 45 and 60mM NaCl) on seed physiological quality of two wheat cultivars (BRS 177 and BRS 179). SUMMARIZE METHODOLOGY. The results allow the following conclusions: the physiological quality (germination and vigor) of wheat seeds, cultivars BRS 179 and BRS 177, decrease with the increase of the salinity. The wheat seeds cv. BRS 179 performs better than BRS 177, mainly in higher salt concentrations (³ 45mM of NaCl). The electric conductivity of wheat seeds increases in function of the increment of the saline concentrations
Portuguese abstract O objetivo do experimento foi determinar a influência de diferentes níveis de sal (zero, 15, 30, 45 e 60mM de NaCl) sobre a qualidade fisiológica de duas cultivares de trigo (BRS 177 e BRS 179). A germinação e a velocidade de germinação de sementes de trigo decresceram com aumento da salinidade, reduzindo a viabilidade e o vigor destas. A salinidade afetou a integridade das membranas, principalmente da cv. BRS 177 que mostrou mais sensibilidade ao estresse salino
