Abstract
Since environmental concerns related to climate change and biodiversity erosion emerged, forest plantations have returned to the heart of international debates. Today's challenge is finding species and planting techniques that increase carbon sequestration and meet the many needs for goods and services from trees. This study aimed to determine the effects of soaking seeds in water, substrate and season on the germination parameters of Terminalia ivorensis A. Chev. seeds in the eco-climatic conditions of Kisangani. The effects of pretreatment, substrate and season were tested to do this. Two treatments (soaking seeds and no soaking) and three substrates (household waste, forest compost and pig droppings) were tested in the dry and rainy seasons. At the end of this experiment, it turns out that the rate of emergence or germination capacity, the germination energy and the germination speed do not vary according to pretreatment and substrate. Only the season significantly influences the emergence rate and the seeds' germination energy. The germination capacity and energy are better in the rainy than the dry season. These results are only a first contribution to understanding factors favouring the use of T. ivorensis in plantations in Kisangani. However, they highlight the need to test longer soaking times and the substrate's effects on seedlings' early growth.
