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.

Vegetative propagation of dacryodes edulis (G. Don) H.J. Lam by marcots, cuttings and micropropagation

Exporter la citation

Air layering (or marcotting) of ‘safou’ (Dacryodes edulis) is most successful with large diameter, horizontal branches with thick bark. However, rooting remains slow and severance is only possible five months after setting the marcots. Application of growth regulators helps to accelerate rooting and reduces the severance period from five to three months. The best results were obtained with IBA. The most effective rooting medium for D. edulis juvenile leafy stem cuttings was found to be sawdust or a sand/sawdust mixture, but no significant effect of hormonal stimulation on rooting was recorded. A technique for disinfecting mature plant material of D. edulis for in vitro propagation is reported. The reputation of D. edulis as a species that is difficult to propagate vegetatively is incorrect. This has important implications for the domestication of the species.
