Propagation of Bersama abyssinica Fresen. var. kandtii (Gilg & Brehmer) Verdc.
Bersama abyssinica Fresen. var. kandtii (Gilg & Brehmer) Verdc., commonly known as Ethiopian berry, is a woody plant that is grown for its edible berries. The plant belongs to the family Meliaceae and is native to Ethiopia, Kenya, and Tanzania. It is a slow-growing plant that can reach up to 10 meters in height. The plant is propagated by various methods that include seeds, cuttings, and air layering.
Propagation by Seeds:
The most common method of propagation for Bersama abyssinica is through seeds. The seeds are collected from ripe fruit and are sown in well-draining soil. Before sowing, the seeds are soaked in water for a day to soften the seed coat. The seeds are then sown at a depth of 1-2 cm and kept in a warm, humid, and bright place. Germination occurs within 2-4 weeks, and the seedlings are transplanted into individual pots when they reach a height of 5-6 cm.
Propagation by Cuttings:
Bersama abyssinica can also be propagated by cuttings. Softwood cuttings are taken from the new growth in late spring or early summer. The cuttings should be around 10-15 cm in length with a diameter of 1 cm. The leaves are removed from the lower end of the cutting, and it is dipped in rooting hormone. The cutting is planted in a well-draining, moisture-retentive soil mix and placed in bright, indirect light. The cutting should root within 4-6 weeks, and it can be transplanted into a larger pot or directly into the ground.
Propagation by Air Layering:
Air layering is another method of propagating Bersama abyssinica. This method is used to propagate larger, established plants. A section of the stem is selected, and a ring of bark is removed from around the stem. A rooting hormone is applied to the wound, and it is wrapped with damp moss. The moss is then wrapped with plastic to retain moisture. After 6-8 weeks, roots should appear, and the rooted section of the stem can be cut and transplanted into its own container or directly into the ground.
Disease Management
Bersama abyssinica Fresen. var. kandtii (Gilg & Brehmer) Verdc. is susceptible to several diseases, including:
- Leaf spot: Caused by the fungus Cercospora. Symptoms include circular, reddish-brown lesions on the leaves. To manage, remove the infected leaves and dispose of them properly. Apply fungicides such as copper-based compounds or chlorothalonil as a preventive measure.
- Anthracnose: Caused by the fungus Colletotrichum gloeosporioides. Symptoms include circular, sunken lesions with dark margins on the leaves. To manage, remove the infected leaves and dispose of them properly. Apply fungicides such as copper-based compounds or chlorothalonil as a preventive measure.
- Powdery mildew: Caused by the fungus Erysiphe cichoracearum. Symptoms include a white powdery growth on the leaves. To manage, remove the infected leaves and dispose of them properly. Apply fungicides such as sulfur-based compounds or potassium bicarbonate as a preventive measure.
Pest Management
Bersama abyssinica Fresen. var. kandtii (Gilg & Brehmer) Verdc. is also susceptible to several pests, including:
- Scale insects: Small, immobile insects that secrete a protective covering over their bodies. Symptoms include yellowing leaves with sticky residue on the surface. To manage, prune heavily infested branches and apply horticultural oil or insecticidal soap.
- Spider mites: Tiny arachnids that suck the sap from the leaves, causing yellowing and bronzing. To manage, spray the plant with water to dislodge the mites and apply insecticidal soap or neem oil.
- Caterpillars: Larvae of moths or butterflies that feed on the leaves and cause defoliation. To manage, handpick the caterpillars and dispose of them properly. Apply biological agents such as Bacillus thuringiensis or spinosad as a preventive measure.
