ETUDE COMPARATIVE ENTRE DEUX PROVENANCES D’Argania spinosa

Abstract

This work presented was founded in the experimental nursery in the Djalfa’s station called INRF, were we undertook a trial breeding in the nursery about tow sources called Argania spinosa to see their adapt to the material of germination and growth in the conditions Semi-arid in the gaol to interuce this speices in the spaces between the dune and would be in the region of oued Djedi (région de Messad, W. Djelfa) Where frosts are almost zero. After four months of aging Argania spinosa in nursery, germination rates of the two sources studied (Tindouf and Mostaganem) between 30 and 58%. Indeed, from the Tindouf gained an advantage in its ability to germinate compared with the provenance of Mostaganem. Throughout the experimental period, Tindouf was distinguished by a greater height growth in height with a value of 29 cm, Diameter growth on the two sources showed the same attention with 4 cm of evolution at the end of the fourth month breeding.
