Leptadenia hastata is a wild edible plant that is highly prized for its culinary and economic value. It is also a medicinal plant very exploited by the Nigerien population. These multiple uses due to harsh climatic conditions put enormous pressure on the species’ stands, which limits its natural regeneration. The present study, conducted in the laboratory of life and earth sciences of the «Ecole Normale Supérieure» of Abdou Moumouni University of Niamey, aims to evaluate the effect of three pretreatments on the germination of two batches of Leptadenia hastata seeds in the laboratory: seeds kept at room temperature in the laboratory for two months (recent seeds) and seeds kept at room temperature in the laboratory for sixteen months (old seeds). In order to assess the latency time, duration, speed and germination rate according to age, the two batches of seeds were subjected to three different pretreatments: seeds soaked in tap water for 12 hours; seeds soaked in tap water for 6 hours; and seeds that did not undergo any pretreatment and were considered as controls. The best latency time and the shortest germination speed are obtained with the recent seeds soaked for 12 hours. But these seeds recorded the lowest germination rate 88.66%. The best germination rate is obtained with the older seeds soaked during 12h (100%), followed by the control old seeds and recent seeds soaked during 6h (98.66% each). The shortest germination time (9 days) was obtained with recent seeds soaked for 6h.
