摘　　要：Ginger (Zingiber officinale Roscoe) is an important culinary and medicinal spice but is rarely cultivated due to the unavailability of seeds. Given the difficulties in adapting to plantlets produced in natural environments, it is important to analyze the survival conditions of ginger plantlets. For this reason, we varied the incubation temperature and humidity as well as the substrate during the weaning phase. Then, we varied the nutrients contained in the watering solution during the hardening phase. The statistical analysis showed that physical factors and substrates significantly influenced (p < 0.0001) plantlet survival. Nutrient solutions significantly influenced the phylogenesis, rhizogenesis, and height growth of the plantlets. The suitable physical factors for good development of plantlets are a temperature of 26.54˚C and a humidity of 96.16%. The 1C2T2TC substrate (1 Compost + 2 Soil + 2 Coconut Peat) had a significant survival rate of approximately 92.5%. During hardening, the Plantzym solution promoted good growth in terms of plantlet height (0.6 cm) and good development of roots (30 roots) and leaves (03 leaves). This work will make it possible to develop a technical seed production sheet for better development of ginger cultivation in Benin.Ginger (Zingiber officinale Roscoe) is an important culinary and medicinal spice but is rarely cultivated due to the unavailability of seeds.
