Abstract
Togo is one of the countries characterized by the highest deforestation rate in the world, caused mainly by the overexploitation of domestic biomass energy. Uapaca togoensis being one of the species appreciated for its strong calorific power, is increasingly overexploited, and its rarefaction in the Togolese forest landscapes becomes worrying hence the need to conduct this study to evaluate the possibilities of its vegetative reproduction. This study contributes to the sustainable development of natural resources by determining the optimal conditions for assisted regeneration of Uapaca togoensis. The approach consisted in conducting a series of nursery trials to determine the impact of the substrate, size of cuttings, sunlight, and apical tip coverage of the plastic film on its germination and budburst capacity. The lower calorific value is determined from samples in dry wood slices of 350g to 500g in five diameter classes. After 33 days, only one unscarred seed germinated in the compost. Substrate type, diameter of cuttings, sunlight, and plastic film significantly influenced the budburst rate and delay. More than 70% of the medium-diameter segments budded compared to 60% and 50% for small and large-diameter segments. More than 80% of the segments exposed to sunlight budded compared to 60% for the shaded segments. The average lower calorific value of dry wood of Uapaca togoensis varies between 7.35 Mj/Kg and 12.12 Mj/Kg depending on the humidity rate and the diameter.
