Propagation Methods:
Seed Propagation:
Propagation through seeds is considered the most reliable method for propagating Mimusops boonei De Wild. However, extracting the seeds from the fruit requires some effort and skill. The fruits should be allowed to ripen completely before harvesting, and the pulp should be removed to expose the seeds within. The seeds should be washed to remove any pulp that may be attached to them. The seeds should be planted in a well-draining soil mixture in a seedbed or a pot. The pots or seedbed should be placed in a humid and warm environment to promote germination. Germination can take between three to six months, depending on the environmental conditions.
Cutting Propagation:
Mimusops boonei De Wild. can be propagated through stem cuttings as well. The cuttings should be taken from mature trees during the dormant season. The cuttings should have at least three nodes and should be treated with rooting hormone to stimulate root formation. The cuttings should be planted in a well-draining soil mixture and placed in a warm and humid environment. The rooting process can take several months.
Air-layering:
Air-layering is another propagation method used for Mimusops boonei De Wild. In air-layering, a branch of the tree is wounded, and rooting hormone is applied to the wounded area. The wounded area is wrapped with a moist medium, such as sphagnum moss, and covered in plastic to maintain humidity. The roots develop in the moist medium, and once they have formed, the branch can be cut and planted in a well-draining soil mixture.
In conclusion, propagation of Mimusops boonei De Wild. can be done through seed, cutting, or air-layering methods. However, each method has its unique challenges, and success rates vary depending on environmental conditions and the propagation method used.
