Propagation of Englerophytum congolense
Englerophytum congolense (De Wild.) Aubrév. & Pellegr., commonly known as African oak or Gabon oak, is a tropical tree species that belongs to the Fabaceae family. The tree is native to the Congo Basin and is widely cultivated for its timber, fruit, and medicinal properties. Propagation of Englerophytum congolense can be done through several methods.
Seed Propagation
Propagation of Englerophytum congolense can be done via seeds. The seeds can be collected from ripe fruits, which mature 4-6 months after pollination. After collecting, the seeds should be cleaned and soaked in water for 24 hours to soften the seed coat. The next step is to scarify the seeds using sandpaper or a knife to help them germinate. The scarified seeds should be sown in a nursery bed filled with a mixture of sand and loamy soil. The seeds should be covered with a thin layer of soil and watered regularly. Germination usually begins within two to three weeks of sowing.
Asexual Propagation
Asexual propagation of Englerophytum congolense can be done using stem cuttings. The best time to take cuttings is during the rainy season when the tree is actively growing. The cuttings should be taken from healthy, disease-free, and mature trees. The cuttings should be about 20-30 cm long and should have 2-3 leaves. The lower leaves should be removed, and the cut end should be dipped in rooting hormone powder. The cuttings should be inserted into a pot filled with a mixture of sand and loamy soil. The pot should be covered with a plastic sheet to maintain high humidity levels. The cuttings will develop roots within 4-6 weeks and can be transplanted to the field.
Budding and Grafting
Budding and grafting are other methods of propagating Englerophytum congolense. Grafting involves joining a piece of stem containing a bud or shoot onto a rootstock. Budding is a specialized form of grafting that involves inserting a single bud onto the rootstock. Both these methods are useful for propagating selected cultivars of Englerophytum congolense. These techniques require skill and experience and are usually done by professional propagators or specialized nurseries.
