Evaluation du patrimoine phoenicicole de la région d’Ouargla

Abstract

Cette étude fait partie du programme d’évaluation du patrimoine phoenicicole dans les régions arides, elle se base sur la détermination, la collection et la classification des cultivars présentent dans la région de Ouargla, dont nous avons a dénombré 55 cultivars certaines possèdent une valeur économique importante, bien que d’autres sont rares et en cour de disparition et d’autre ont complètement disparus. La différence entre ces cultivars est du essentiellement aux caractères morphologiques des dattes plus que les grains parmi ces cultivars on peut citer ; Deglet-Nour, Ghars, Degla-Beida, Litim, Mizit, Hamraya, Tamesrit, Timjouhart, Tafezouine, Bajmil, Harchaya,…etc. Les palmiers issues des grains se différencient des autres variétés surtout du coté des caractères généraux, donc il est important de les diagnostiquer puisque ils contribuent dans la diversité des palmiers d’une par et d’autre part la reproduction par rejet qui a vu une grande variation dans la mise en valeur à cause de la progression que connait le marché des dattes. Et pour la préservation de ces cultivars on propose : - La collection des variétés rares et les distribuer aux agriculteurs. -la création d’un jardin botanique regroupant les cultivars de dattes. Abstract: This study is part of the asset valuation palm growing in arid regions, it is based on identification, collection and classification of the dates are in the region of Ouargla, we were 55 cultivars have some significant economic value , while others are rare and court of missing and others have completely disappeared. The difference between these cultivars is mainly due to morphological dates more than grains of these cultivars include; Deglet-Nour, Ghars Degla-Beida Litim, Mizit, Hamraya, Tamesrit, Timjouhart, Tafezouine, Bajmil, Harchaya, ... etc.. The palm trees from seeds of other varieties differ mostly on the side of the general characteristics, so it is important to diagnose since they contribute to the diversity of the palm of one per second and reproductive rejection that has seen a great variation in development because of the progress that knows the market dates. And for the preservation of these varieties are proposed: * The collection of rare varieties and distribute them to farmers* Creating a botanical garden comprising cultivars of dates.
