This PhD. Project aimed to understanding of the role of abiotic priming as a stress alleviation phenomenon. Plants have developed sophisticated physiological mechanisms to cope with adversity. An early stress can imprint a “memory” in plants (priming) and improve their tolerance against a subsequent stress exposure. The results obtained on this thesis showed that the effects of priming on improving plant’s tolerance are dependable on their: cultivar, duration, timing and intensity. This thesis could contribute to elucidate the genotypic dependence of priming. Our findings showed that drought priming could enhance tolerance within plant’s life cycle and, at the same time, cause no cost in grain yield under non-stressed conditions.
