Gilletiodendron pierreanum (Harms) J.Léonard, commonly known as Mubai, is a tropical tree species endemic to West and Central Africa. The plant is found in Cameroon, Gabon, Democratic Republic of Congo, and Congo. It prefers lowland rainforests with humid and hot conditions, where it grows up to 40 meters high.
Common Names
Aside from Mubai, Gilletiodendron pierreanum is also known by various common names such as M'bolo, Essingang, Essok, Fumpu, Muenge, and several other African names depending on the location.
Uses
Gilletiodendron pierreanum is a valuable timber tree that produces a durable and high-quality wood used for various purposes, including construction, furniture, and carving. The wood is also resistant to termites, making it a popular choice in the construction of buildings. Additionally, the bark, leaves, and roots of the tree are useful in traditional medicine as they contain compounds with anti-inflammatory and anti-malarial properties.
General Appearance
The tree has a straight trunk with a relatively small and erect crown. Its bark is rough and fissured, varying from grayish-brown to dark brown color. The leaves of Gilletiodendron pierreanum are compound and imparipinnate, with 5-11 leaflets. The tree produces great inflorescences that contain small and inconspicuous flowers. After the flowering period, it bears oblong or ovoid fruit that measures 15–20 cm long and 10 cm wide. The fruit is a hard-shelled nut containing edible kernels that have a sweet or oily flavor.
Light Requirements
Gilletiodendron pierreanum (Harms) J.Léonard thrives in partially shaded areas where it can get sufficient sunlight. As an understory tree, it prefers dappled sunlight or moderate shade provided by other larger trees. Direct sunlight can damage the foliage, and therefore it is essential to protect it from excessive sunlight exposure.
Temperature Requirements
This plant is native to tropical areas, and thus it requires high humidity and warm temperatures to thrive. It grows best in temperatures between 18°C and 24°C, with a minimum temperature of around 10°C. Freezing temperatures should be avoided, as they can be damaging to the plant. A warm, stable temperature throughout the year is ideal for healthy growth.
Soil Requirements
Gilletiodendron pierreanum (Harms) J.Léonard prefers well-draining, fertile soils to grow well. Clay soil is the ideal growing medium as it retains moisture and nutrients, which are essential for growth. The plant can also grow in sandy and loamy soils, but the soil must be well-draining to avoid waterlogging and root rot. The pH level of the soil should be between 5.0 and 6.5 for optimal growth.
Cultivation of Gilletiodendron Pierreanum
Gilletiodendron pierreanum is a perennial plant that thrives well in a humid and shady environment. It is a slow-growing tree and grows up to a height of 15 meters. The tree requires well-draining soil, rich in organic matter like tree barks, leaves, and compost.
Water Requirements
Gilletiodendron pierreanum requires moderate watering. The soil should be moist but not waterlogged. Watering should be done when the soil is dry to the touch but not bone dry. Too much watering can cause root rot, which can be detrimental to the plant's growth and health.
Fertilization
The plant requires regular fertilization to support growth and development. You can fertilize your Gilletiodendron pierreanum using organic fertilizers like compost, manure, and worm castings. Alternatively, you can use a balanced chemical fertilizer with a nitrogen-phosphorus-potassium (NPK) ratio of 10:10:10. Fertilizers should be applied during the growing season for the best results.
Pruning
Pruning of Gilletiodendron pierreanum is essential to promote proper growth and development. It should be done after the flowering season to control the size and shape of the tree. You can prune your plant by removing any dead, damaged, or diseased parts. You can also remove any crossed branches and those that rub against each other, as they can create wounds that can allow pests and disease to invade the plant.
Conclusion
Gilletiodendron pierreanum is an ideal plant for those who love perennial trees. With proper care and cultivation, you can enjoy the beauty of this magnificent plant in your garden or home. Ensure you provide it with the right soil, water, and fertilizer, and remember to prune it to enhance its growth and overall look.
Propagation of Gilletiodendron pierreanum (Harms) J.Léonard
Gilletiodendron pierreanum (Harms) J.Léonard can be propagated using various methods. The most common methods include seed germination, stem cuttings, and air layering.
Seed Propagation
To propagate Gilletiodendron pierreanum (Harms) J.Léonard through seed, mature seeds should be collected and sown in well-draining soil in a seedling tray. The seedlings should be kept in a warm and humid environment until they reach a height of 10 to 15 cm. Once the seedlings have reached this height, they can be transplanted into individual pots with well-draining soil.
Stem Cutting Propagation
Gilletiodendron pierreanum (Harms) J.Léonard can also be propagated through stem cuttings. The stem cuttings should be taken from the parent plant during the growing season. The cuttings should have at least two nodes and should be 10 to 15 cm long. The lower leaves should be removed, and the cutting should be planted in well-draining soil. The soil should be kept moist until the cutting has established roots.
Air Layering Propagation
Air layering is another propagation method that can be used for Gilletiodendron pierreanum (Harms) J.Léonard. The process involves making a small cut in the bark of a mature plant and wrapping a moist growing medium, such as sphagnum moss, around the cut area. The area is then wrapped in plastic to create a humid environment. Once roots have formed, the cutting can be removed from the parent plant and planted in well-draining soil.
Disease and Pest Management for Gilletiodendron pierreanum (Harms) J.Léonard
Gilletiodendron pierreanum (Harms) J.Léonard, also known as the African teak, is susceptible to various pests and diseases. Here are some common ones and ways to manage them.
Anthracnose
Anthracnose is a fungal disease that attacks the leaves and twigs of Gilletiodendron pierreanum (Harms) J.Léonard and causes them to wilt and die. To manage anthracnose, remove any infected leaves or twigs and dispose of them properly. You can also use fungicides to control the disease.
Leaf spots
Leaf spots are caused by several fungi and can affect the leaves of the African teak. They show up as small, discolored spots on the leaves, which may merge to form larger ones. To manage leaf spots, remove any affected leaves and dispose of them properly. You can also use fungicides and make sure the plant is not overwatered.
Scale insects
Scale insects are common pests that can infest Gilletiodendron pierreanum (Harms) J.Léonard and cause the leaves to turn yellow and drop prematurely. To manage scale, use insecticidal soap, horticultural oil, or insecticides to control the pests. You can also use a soft-bristle brush to physically remove the scales from the plant.
Caterpillars
Caterpillars can also affect the African teak by chewing on its leaves, which can cause significant damage to the plant. To manage caterpillars, you can remove them by hand or use insecticides.
Mites
Mites are another common pest that can attack Gilletiodendron pierreanum (Harms) J.Léonard. You can detect them by noticing small yellow or white spots on the leaves. To manage mites, use a horticultural oil or insecticidal soap, or you can introduce natural predators like lady beetles or lacewings to the plant.
Regularly inspecting the plant and taking proper care of it, such as watering it appropriately and providing it with adequate nutrients, can also help prevent various diseases and pests that can affect it.
