Other claims from this paper (14)
- Observation Cultivar Rihane was well adapted and performed better than Testour under the tested conditions.
- Intervention effect Salt stress reduced barley growth characteristics (dry weights and relative growth rates).
- Intervention effect Salt stress significantly decreased relative water contents, total chlorophyll and soluble proteins compared with controls.
- Intervention effect Salt stress significantly decreased total carbohydrates and K+ contents compared with controls.
- Intervention effect Added AsA boosted barley seedling growth under saline conditions.
- Intervention effect Added AsA decreased Na+ contents under saline conditions.
- Intervention effect Added AsA increased total chlorophyll content, K+ contents and K+/Na+ ratios under saline conditions.
- Intervention effect Supplemental AsA increased non-enzymatic antioxidants (total phenolics and flavonoids) in salt-treated barley.
- Intervention effect Supplemental AsA increased enzymatic antioxidant components SOD, CAT and GPX in salt-treated barley.
- Intervention effect Supplemental AsA caused a remarkable decrease in MDA contents in leaves and roots of salt-treated barley.
- Intervention effect AsA addition noticeably increased accumulation of proline and glycine betaine.
- Mechanism AsA retains additional osmolality, upholding RWC and promoting seedling growth, particularly in the salt-sensitive genotype.
- Recommendation Exogenous AsA application may be suggested as a strategy to overcome salinity-mediated impairment of barley, particularly salt-sensitive genotypes.
- Mechanism AsA improves osmotic and ionic homeostasis by upregulating the antioxidant defense system.
