CIFOR-ICRAF s’attaque aux défis et aux opportunités locales tout en apportant des solutions aux problèmes mondiaux concernant les forêts, les paysages, les populations et la planète.

Nous fournissons des preuves et des solutions concrètes pour transformer l’utilisation des terres et la production alimentaire : conserver et restaurer les écosystèmes, répondre aux crises mondiales du climat, de la malnutrition, de la biodiversité et de la désertification. En bref, nous améliorons la vie des populations.

CIFOR-ICRAF publie chaque année plus de 750 publications sur l’agroforesterie, les forêts et le changement climatique, la restauration des paysages, les droits, la politique forestière et bien d’autres sujets encore, et ce dans plusieurs langues. .

CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Micropropagation of allanblackia stuhlmannii ‘clusiaceae’, an economically important wild tree species

Exporter la citation

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
