Overview of Synsepalum revolutum
Synsepalum revolutum is a tree species belonging to the Sapotaceae family. The plant is commonly found in West Africa, particularly in Nigeria, Ghana, Cameroon, and Sierra Leone. It is locally known as "Eyin Olobe" in Nigeria, "Agogo" or "Akogo" in Cameroon, and "Obom" in Ghana.
Appearance of Synsepalum revolutum
The tree grows up to 20 meters tall and has a narrow, conical shape. Its bark has a gray or brownish color, with deep fissures that run vertically to the surface. The leaves are dark green and glossy, and they have an elliptic or ovate shape, which turns reddish before falling off. The fruit of Synsepalum revolutum is a hard, green berry, which turns red or orange when fully ripe. The berry has a globose shape with a diameter of about 3 cm.
Uses of Synsepalum revolutum
The fruit of Synsepalum revolutum is edible and is highly valued for its sweet taste. It is used in the production of jams, jellies, and wines. The fruit is also consumed traditionally by local communities as a remedy for various ailments such as diarrhea, stomach ache, and toothache.
The bark of the tree is used in the production of textiles and ropes due to its fibrous nature. The wood is hard and durable, and it is used in the construction of furniture, utensils, and musical instruments. The plant also has ornamental value and is grown in gardens and parks for its aesthetic appeal.
Light Requirements
Synsepalum revolutum prefers bright, indirect light. It can tolerate partial shade, but direct sunlight may burn the leaves and lead to stunted growth. Natural light filtered through a sheer curtain or blinds is ideal for this plant.
Temperature Requirements
This plant is native to tropical regions of Africa, so it thrives in warm temperatures. Ideal temperatures for Synsepalum revolutum are between 60 and 85 degrees Fahrenheit. Temperatures below 55 degrees Fahrenheit can harm this plant, and lower than 45 degrees Fahrenheit can be fatal.
Soil Requirements
The plant prefers well-draining, slightly acidic soil with a pH between 5.5 to 6.5. A mix of loam, peat moss, and sand is suitable for this plant. The soil should be moist but not waterlogged. Overwatering can lead to root rot, so it's essential to let the soil dry out partially before watering again.
Cultivation Methods
Synsepalum revolutum is a slow-growing, evergreen shrub that thrives best in tropical climates. It needs well-drained soil and should be planted in a location that receives partial to full sunlight. Planting should be done during the rainy season as the plant requires consistent moisture for vigorous growth.
Watering Needs
The watering needs of Synsepalum revolutum are moderate. They should be watered regularly to keep the soil moist but not waterlogged. It is crucial to ensure the soil drains well. During the dry season, it is essential to water the plant frequently to help it retain its leaves and remain healthy.
Fertilization
To encourage healthy growth, Synsepalum revolutum should be fertilized every two to three months, especially during the growing season. Use a balanced organic fertilizer and apply it according to the package directions. Avoid over-fertilizing as it can cause damage to the plant.
Pruning
Synsepalum revolutum requires minimal pruning, and it should only be done to maintain a specific shape or to remove dead or damaged branches. It is best to prune after flowering to avoid interfering with the blooming process. Pruning should be done in the morning or evening when the temperatures are cooler, and tools should be sterilized before use to prevent the spread of disease.
Propagation of Synsepalum revolutum
Synsepalum revolutum (Baker) T.D.Penn., commonly known as the African star apple, is a slow-growing evergreen tree that is native to Africa. The plant is propagated through both sexual and asexual methods.
Sexual Propagation
The tree produces small, white, and fragrant flowers that are pollinated by insects. The fruit is a large berry that contains few to several seeds. Sexual propagation involves collecting seeds from mature fruits, washing and drying them, and planting them in well-drained soil. The seeds should be planted in individual containers to prevent root damage during transplanting.
Asexual Propagation
Asexual propagation methods include grafting and stem cutting. Grafting involves selecting a scion from a healthy, mature tree and attaching it to a rootstock. The scion should be at least 8 to 10cm long, and the graft union should be protected with a grafting tape. Stem cutting propagation involves selecting a healthy stem of at least 30cm long and cutting it at a 45-degree angle below the node. The cuttings should be treated with rooting hormone and planted in well-drained soil in individual containers. The cuttings should be watered regularly and kept at a temperature between 25-30 °C.
Propagation of Synsepalum revolutum can be slow and challenging, but it is rewarding for gardeners and farmers alike. Both sexual and asexual propagation methods have their advantages and disadvantages, and the choice of method depends on the availability of resources, climate, and time.
