Banque de graines du sol et déterminants de la germination du tali, Erythrophleum suaveolens (Guill. & Perr.) Brenan

Abstract: Cette étude évalue l’abondance des graines d’Erythrophleum suaveolens dans la banque de semences du sol des forêts denses humides d’Afrique centrale. Les travaux ont été menés au Nord-Congo dans deux types forestiers : la forêt à Celtis sur des sols argilo-sableux à sablo-argileux et la forêt à Manilkara sur des sols sableux. Les tiges d’E. suaveolens (dhp ≥ 10 cm) ont été inventoriées dans deux blocs de 400 ha, et les structures diamétriques de leurs populations ont été comparées. En outre, 80 fosses (2 x 40 … Show more

“…The high abundance of herbaceous species in the two savannas and the presence of a single woody species clearly demonstrate the need to preserve these savannas' ecosystems in the face of anthropogenic disturbances. Consequently, reforestation to improve the regeneration of wooded species within the two savannas is all the urgently needed [70] [71].…”

“…At the end of this study, we can overall retain that: 1) soil seed bank characteristics vary from one plot to another; 2) seed stocks were substantial up to 20 cm soil depth, and some pioneer tree species had viable seeds in the deeper soil layers although they were absent in superficial layers; and 3) commercial tree species were not well represented in the soil seed bank of the two Marantaceae forests plots. Consequently, the study suggests silvicultural practices to improve the regeneration of commercial tree species in Marantaceae forests [3] [17] [41].…”

“…The number of viable seeds in the soil samples has been estimated by the germination method [3] [10] [17]. The samples were sieved before the start of the experiment, in order to eliminate plant elements and minerals elements (leaves, smithereens of wood).…”
