Figs are a traditional pantry staple for healthy eating in Middle Eastern and North African countries as fig trees grow abundantly in such hot and dry climates. Despite the importance of this species, chemotypic diversity has gone unheeded and therefore its valorization pathways remain poorly documented. For this reason, high-pressure liquid chroma...

(Promotion of pomegranate (Punica granatum) as a resilient crop to climate change in the piedmont of the middle Atlas and the Saiss plain) L’objectif global est décliné en objectifs spécifiques, qui sont : - Sélection et détermination des profils variétaux de grenadier à promouvoir dans les zones de piémonts et de moyennes altitudes via une évaluation des ressources génétique de l’espèce au Maroc. Le choix du matériel génétique va prendre en considération les modes de valorisation adéquates soit consommation en frais ou différents types de transformation ; - Identification du pourvoir adaptatif de grenadier aux nouvelles zones par l’étude des aspects de croissance et de développement et les caractéristiques physiologique de l’espèce ainsi la stabilité de la production et sa qualité et celle du jus des fruits ; - Mise en évidence des besoins réels en eau d’irrigation de grenadier et son optimisation par le recours à l’irrigation déficitaire ou d’appointe. Ainsi, l’étude de la qualité de fruit et la stabilité de jus sous différent régimes ; - Promouvoir des modes et procédés de valorisation adéquats et rentables de la culture de grenadier en prenant en compte le type variétal et des procédés écologiques et sanitaires. - Le renforcement des capacités techniques et organisationnelles des agriculteurs des zones concernées par le projet est réalisé par la sensibilisation, la formation et l’accompagnement.
