Abstract

In order to study the effect of SALINITY STRESS on morpho-physiological traits of WHEAT GENOTYPES, two experiments were carried out at the two locations (Ece=1.5, Ece=10 dS/m) of Miandoab Agricultural Research Station, north-west of Iran, using 10 genotypes. The experimental design was randomized complete block with five replications. The result of combined analysis of variance revealed significant differences between the two experimental conditions (saline and non saline) and among genotypes for all the studied characters except potassium content of the flag leaf under two conditions. Under SALINITY STRESS, total dry matter, grain yield and its components, K/Na ratio as well as potassium accumulation decreased, whereas Na ion accumulation, soluble sugars and proline content increased. Arvand and Kavir cultivars were high yielding genotypes under salinity and normal conditions, respectively. In contrast, Roshan and Shole produced lowest grain yield under both conditions. Arvand cultivar with minimum salinity susceptibility index had also the least accumulation of Na ion, medium amount of K ion and maximum K/Na ratio. In contrast, Falat cultivar showed the lowest amount of K ion, medium accumulation of Na and minimum K/Na ratio under salinity condition. Overall, Arvand and Falat genotypes had maximum and minimum accumulation of compatible solutes (proline and soluble sugars), respectively. Among yield components, maximum reduction under salinity condition belonged to the number of spikes per square meter.
