Assessing the Adaptive Mechanisms of Two Bread Wheat (Triticum aestivum L.) Genotypes to Salinity Stress

Popis výsledku v původním jazyce

This work deals with the assessment of physiological and biochemical responses to salt stress, as well as the regulation of the expression of the K Na transporter geneTaHKT1,5 of two Triticum aestivum L. genotypes with contrasting tolerance. According to the observations, salinity stress caused lipid peroxidation, accumulation of soluble sugars and proline, decreased osmotic potential, Fv Fm value, and K Na ratio, and increased the activity of antioxidant enzymes in both genotypes. In the salt tolerant genotype, the activity of enzymes, the amounts of soluble sugars and proline were higher, the osmotic potential and the lipid peroxidation were lower than in the sensitive one, and the Fv Fm value remained unchanged. A comparison of the accumulation of Na and K ions in the roots and leaves showed that the Na content in the leaves is lower. The selective transport of K ions from roots to leaves was more efficient in the salttolerant genotype Mirbashir128, consequently, the K Na ratio in the leaves and r
