Physiology of salinity tolerance in Aegilops cylindrica

Overview
Aegilops cylindrica
species is one of the valuable gene pool of wheat for the understanding of salinity-tolerance mechanisms such as Na
+
exclusion. Eighty-eight
Ae

cylindrica
genotypes were collected from saline and non-saline areas of West Iran and used in this study. Physiological and morphological traits including shoot and root fresh and dry weights, leaf MDA and H

concentrations, K

/Na

ratio of leaves and salinity tolerance index were evaluated. Salinity stress caused significant increases in MDA and H

concentrations of root and leaves, while it led to significant decline in the remaining traits. Although dry matter correlated with leaf K

/Na

ratio (
R

= 0.48), the regression coefficient was higher for leaf Na
+
concentration (
R

= 0.58). The results of principal component analysis revealed two components (PC
1
and PC
2
) which totally justified 52.47 and 48.02 % of total variations of the traits in control and salinity stress conditions, respectively. Three hypersalinity-tolerant genotypes originating from the shore areas resulted from shrinking of Uremia Salt Lake and depicted by the highest PC

/Na

ratio as well as the lower Na

concentration in leaves and roots. The high Na

cylindrica
genotypes open up new avenues for further analyses at the cellular and molecular levels to address the role of C genome as well as the complex relations between C and D genomes to cope with hypersalinity stress via ionic homeostasis.
