Propagation of Allanblackia floribunda Oliv. var. gabonensis Pellegr.
The propagation of Allanblackia floribunda Oliv. var. gabonensis Pellegr., commonly known as Gabon butter tree, can be done through different methods such as seeds, cuttings, budding, and grafting.
Seeds
Seeds are the most common propagation method employed for Allanblackia floribunda Oliv. var. gabonensis Pellegr. The seeds can be collected from ripe fruits, which usually fall to the ground. These seeds must be cleaned and sown without delay because they do not have a long shelf life. The seeds should be sown in a well-prepared seedbed with sandy soil mixed with compost or manure. They should be sown at a depth of 2 cm and 15 cm apart. Germination usually starts after 3-4 weeks, and the seedlings can be transplanted to their permanent planting site after two to three months.
Cuttings
Allanblackia floribunda Oliv. var. gabonensis Pellegr. can also be propagated by stem cuttings. This method is suitable when the plant has matured and is not producing enough seeds. The cuttings should be taken from a healthy and mature tree and should be about 30 cm long with three to four nodes. The leaves on the lower nodes should be removed, leaving two or three leaves on the upper nodes. The cuttings should be planted in a well-prepared rooting medium, such as sand or vermiculite, to encourage root growth. The cuttings should be watered frequently until they have rooted and can be transplanted after six to eight weeks.
Budding
Budding is another technique that can be used to propagate Allanblackia floribunda Oliv. var. gabonensis Pellegr. It involves taking a bud from a mature tree and inserting it under the bark of a seedling or young tree of the same species under the bark. This method is usually employed when specific desirable traits of a particular tree are being sought in a new tree. The best time to bud is during the rainy season when the bark is luscious and easy to manipulate. After budding, the plant should be watered regularly for successful growth.
Grafting
Grafting is a more complex propagation method that involves fusing the stem of a desired tree onto the rootstock of another related tree. This method can be used to propagate Allanblackia floribunda Oliv. var. gabonensis Pellegr. However, it is not commonly used because it requires specialized skills and a considerable amount of time and investment. Grafting can be done by using the scion from a mature and healthy tree with the desired characteristics. The scion is then fitted onto the tree's rootstock and secured in place with grafting tape or wax. The tree is then left to grow for several months until the graft is successful.
