Allanblackia stuhlmannii is an endangered forest tree valued for its edible nut oil which has high potential for commercialization. This tree grows naturally in the Eastern Arc Mountains of Tanzania. Regeneration of A. stuhlmannii via seed is slow and low. Rooting of cuttings is poor, while survival rate of grafted materials is dismal. The limited regenerative potential of A. stuhlmannii hinders sustainable nut harvesting from the wild to meet market demand. A private-public partnership known as ‘Novella Africa’ is engaged in the domestication of members of Allanblackia spp. for commercial oil production. To achieve mass production, the amenability of A. stuhlmannii to micropropagation technique was examined in this study. A series of sterilization and micropropagtion experiments were conducted on plant material collected from Amani Nature Reserve in Tanzania. Sodium hypochlorite, formaldehyde and Redomil® were the reagents used in the sterilization protocol. Explants were best surface sterilized after subjection to 2% Redomil® solution and exposure to 8% sodium hypochlorite solution for 10 minutes. Eight basal media were tested for their suitability in micropropagation of A. stuhlmannii. McCown’s WPM which had 88.89% explants survival rate was selected for micropropagation of A. stuhlmannii. Microshoots were induced from shoot tips and internodal explants of A. stuhlmannii cultured on WPM fortified with different treatments of PGRs, (P
