Salt-tolerance of Wheat (Triticum aestivum L.) Genotypes: A Lysimeter Study
Javaid Akhtar, M. Zahid, S. Parveen and A. Naseem

To see the effect of salinity on wheat lysimeter experiment was conducted by growing six wheat genotypes. The experiment included three treatments i.e. EC, =4.75 (control), 7.5 and 15.0 dS m–1 with four replications. Data regarding number tillers, grain and straw yield per plant were recorded at harvesting. Lead sap was extracted from leaf samples collected at booting stage and analyzed for N+, K+ and Cl‾ concentration. Yield parameters and K+ concentration decreased, while Na+ and Cl‾ concentration increased with an increase in salinity. Genotype 234-1 had the highest value of its yield parameters along with high concentration of Na+ and CI‾ and was declared tolerant as it might had compartmentalized these ions. Two genotypes WC-73 and SAR-5 produced the lowest value of yield parameters and were declared sensitive. But the Na+ and Cl‾ concentrations of WC-73 was low while that of SARC-5 was high. This difference in their sensitivity could be attributed of genetic constitution.
