DOMESTICATION OFDACRYODES EDULIS: STATE-OF-THE-ART

The effect of land use systems on tree diversity: farmer preference and species composition of cocoa-based agroecosystems in Ghana

“…Valuable indigenous non-timber forest product species will lose importance with increasing resource use intensification without specific efforts to promote them (Sonwa et al 2007) which integrate farmers' species selectivity (Asare 2006). However, as pointed out by Tchoundjeu et al (2002) the domestication of these, and other, species needs to take into consideration the requirements and knowledge of small-scale, resource-poor farmers and their subsistence farming systems. They recommend a more participatory approach to the domestication of high-value agroforestry tree species based on: priority setting by farmers; germplasm collection; lowtechnology vegetative propagation in village nurseries; the genetic characterization of the marketable products for consumption and processing; the integration of these species into agroforests managed by subsistence farmers; and the expansion of markets for the products.…”

Feasibility of Farmer-Managed Vegetative Propagation Nurseries in Cameroon

“…Therefore, developing techniques for rooting juvenile and mature plant material was one of the key activities. On-station experiments on rooting of juvenile cuttings in low-cost non-mist propagators (Leakey et a/., 1990;Tchoundjeu et a/., 1997;Mbile et a/., 2004) Tchoundjeu et al, 2002b;Mialoundama et al, 2002). In addition, air layering, a method of propagating mature material that may fruit at an early age, has been successful for most of these species (Leakey and Tchoundjeu,200 I).…”

Agroforestry: Participatory Domestication of Trees

“…In the longest-running example of participatory domestication in agroforestry trees, the researchers have fed their outputs to NGO partners through training-of-trainers courses and by acting as mentors to the NGO-managed farmertraining schools (or Rural Resource Centers) established in pilot villages (Tchoundjeu et al, 2002(Tchoundjeu et al, , 2006Asaah et al, 2011). As it will be seen in the Section Techniques, the farmers in this partnership have contributed their knowledge about the use and importance of local species, the range of variation in different traits of relevance to genetic selection, and their traditional knowledge (TK) about the role of these species in local culture and tradition.…”
