چکیده
Salt stress significantly limit wheat crop productivity worldwide. Exposure to non-lethal levels of salt stress, referred as "salt-priming", allows plants persist subsequent lethal conditions; the priming effect continues even after an extended stress-free period. This study attempted evaluate effectiveness salt-induced approach cope with toxic effects long-term salinity in wheat. After 22 days gradual acclamation reach 250 mM NaCl, were recovered for eight and finally shocked NaCl (priming+shock) 7 days. that, physiological parameters gene expression six salt-responsive genes assessed. Additionally, 120 germination (at end season), agronomic traits recorded. Analysis agronomical revealed higher salt-pretreated group than non-pretreated (shock only). Consistently, maintained photosynthetic pigments level decreased proline MDA content non-pretreated, suggesting enhanced tolerance. Moreover, sustained high expressional (TaNHX1, TaSOS1, TaSOS4, TaHKT1, TaHKT2, TaAKT1) comparing indicating a vital role ion homeostasis conferring Ultimately, this finding could facilitate novel smart approaches improve under stress.

متن کاملAssessment of agro-physiological traits for salt tolerance in drought-tolerant wheat genotypes
Salt stress is one of the major constraints for wheat cultivation inIranand leads to a considerable loss in crop yield each year. In high salinity soils, the reduced osmotic potential of soil solutes may cause physiological drought. In this study the salt tolerance of different drought-tolerant bread wheat genotypes were studied by examining various agronomic and physiological traits, inclu...

متن کاملNuclear and Cytoplasmic Inheritance of Salt Tolerance in Bread Wheat Plants Based on Ion Contents and Biological Yield
Although inter-variety variability for salt tolerance has been reported in bread wheat plants, little information is available on the genetic control of ion contents and biomass yield under saline conditions. A diallel cross, including reciprocals of two salt tolerant, two moderately tolerant and two sensitive Iranian and exotic bread wheat varieties, was analyzed to investigate the inheritance...
