Balanites aegyptiaca est l’une des plantes a usages multiples au Niger tres appreciee par les populations. Cette etude conduite au Centre Regional de Recherche Agronomique de Zinder, vise a etudier la germination et l’evolution des plantules de cette espece. Les essais de germination ont ete effectues dans des planches rectangulaires sur six types de traitements pendant 3 mois et le suivi de croissance des plantules dans des pots plastiques enfouis dans le sol pendant 6 mois. L’etude a montre que l’ingestion des fruits de Balanites aegyptiaca par les chevres reduit significativement la dormance tegumentaire. Les graines extraites des noyaux qui ont transite par le tractus digestif des chevres ont le taux de germination le plus eleve (76,87%) et le taux de germination le plus faible a ete obtenu avec les fruits entiers (38,12%). Apres 6 mois de suivi, la croissance du pivot racinaire des plantules (78,59±9,04 cm) est plus importante que celle de la partie aerienne (61,8±6,2 cm). Cette etude permet d’envisager la production des plants de Balanites aegyptiaca en vue de sa conservation durable. © 2019 International Formulae Group.

Del. English Abstract Balanites aegyptiaca is one of multipurpose plants in Niger very appreciated by the populations. This study conducted at Zinder’s Regional Center for Agricultural Research, aims to study the germination and evolution of seedlings of this species. The germination tests were carried into rectangular plates on six types of treatment for 3 months and the growth monitoring of seedlings in plastic pots buried in the soil for 6 months. The study showed that ingestion of Balanites aegyptiaca fruits by goats significantly reduces tegumentary dormancy. Seeds extracted from cores that have passed into the digestive tract of goats have the highest germination rate (76.87%) and the lowest germination rate was obtained with intact fruits (38.12%). After 6 months of monitoring, the pivot root growth of seedlings (78.59±9.04 cm) is greater than the aerial part (61.8±6.2 cm). This study allows envisaging the production of Balanites aegyptiaca plants for its sustainable conservation. © 2019 International Formulae Group.
