Development of propagation protocols for Allanblackia species Final report to Unilever

Export citation

Allanblackia species (Family Clusiaceae) are high value multipurpose indigenous fruit tree species in the West, East and Central African regions. Benets derived from the tree include shade, timber, medicine and seed oil (Abbiw 1990; Ofori et al., 2006). The seed oil is of prime importance as a foreign exchange earner and is being developed as a rural-based enterprise in many African countries notably Ghana, Nigeria, Cameroon and Tanzania. Currently over 100,000 tons of Allanblackia oil is required annually but only about 200 tons are supplied on average from Ghana, Nigeria and Tanzania (Oppong 2008). In order to bridge the gap between demand and supply, over 8 million fruiting trees need to be available. This calls for the domestication of the species of which one crucial aspect is the development of propagation techniques for mass production of planting stocks
