Drought stress memory in a germplasm of synthetic and common wheat: antioxidant system, physiological and morphological consequences.

ABSTRACT: Plants have evolved mechanisms of adaptation to fluctuations in their environmental conditions that have been given the term "stress memory". Synthetic wheat offers new hope for breeders to restore useful genes lost during the genetic bottleneck. We aimed to test whether drought priming and seed priming could improve drought tolerance in a diverse germplasm of synthetic and common wheat under field conditions. In this research, 27 wheat genotypes (including 20 synthetics, 4 common local and 3 common exotic bread wheat) were field evaluated under four water environments. These treatments included: 1) normal condition (N), plants were irrigated when 40% of the total available soil water was depleted from the root-zone, 2) seed priming-secondary stress (SD2), only water stress was applied at
