Propagation of Bersama subulata Hutch. & Dalziel
Bersama subulata Hutch. & Dalziel is a dioecious tree species that belongs to the family Meliaceae. The species is native to tropical Africa and is commonly found in savannah woodlands and hillsides. In order to propagate the species, it is important to consider a few key aspects of its biology.
Seed propagation
The most common method of propagating Bersama subulata is through seed propagation. The seeds of the species are contained within a fleshy, orange fruit that is approximately the size of a small grapefruit. The fruit can be harvested and the seeds extracted by hand. Once the seeds have been removed, they should be washed and dried before being sown.
The seeds of Bersama subulata have a hard outer shell, which can make germination difficult. In order to improve germination rates, the seeds can be soaked in water for several days prior to sowing. This process softens the seed coat and can help to break down any inhibitors that may be present.
The seeds should be sown in a seedling tray filled with well-draining soil. They should be covered with a thin layer of soil and lightly watered. The trays should be kept in a warm, well-lit area and watered frequently to keep the soil moist. Germination can take up to several weeks, but once the seedlings are established, they can be transplanted into larger pots or directly into the ground.
Vegetative propagation
In addition to seed propagation, Bersama subulata can be propagated through vegetative means. The most common method is through stem cuttings. Cuttings should be taken from mature, healthy trees during the dormant season and treated with a rooting hormone to improve success rates.
Once treated, the cuttings should be planted in a well-draining soil mix and kept in a warm, humid environment. They should be watered frequently to ensure that the soil remains moist and should be kept out of direct sunlight until they have established roots.
Overall, Bersama subulata can be propagated through both seed and vegetative means. By following the proper techniques and providing the appropriate growing conditions, it is possible to propagate healthy, viable specimens of this unique and valuable species.
