Abstract | ||||
Proline content, chlorophyll pigment and potassium/sodium ratio (Na+/K+) of five different genotypes, Edkawy, Castle Rock and Budai Torpe and their hybrids EХC and EХB were significantly increased in proline content and Na+/K+, and significantly lowered in chlorophyll content by the rise of salinization levels 1.2, 2, 5, 10, 15 dS/m. The two hybrids gave a higher response to salinity; this is observed in the increase in Na and proline in the same time K concentration decreased. Edkawy showed mid values between the other parents and the hybrids. | ||||
