The fruit is a large edible drupe that is spherical or oblate in shape. It has a diameter of 7-10 cm and a weight of 120-400 g with a green to yellowish-green color when unripe and greenish-yellow to yellow when ripe. The fruit also has a sweet and aromatic taste with a custard-like texture, hence the name “custard apple.”Uses
The African custard apple is widely used for its medicinal properties. The leaves and bark of the plant are used in treating various ailments such as bronchitis, pneumonia, malaria, and stomach disorders. The fruit is also used to treat dysentery and diarrhea. Additionally, the seeds of the fruit are used in treating intestinal worms and other parasitic infections. In some African countries, the fruit is consumed as a food source due to its high nutritional value. The fruit is rich in antioxidants, carbohydrates, and essential vitamins and minerals such as Vitamin C, potassium, and calcium. The fruit is also used to make jams, jellies, and other sweet delicacies.Conclusion
In conclusion, Pleiocarpa pycnantha (K.Schum.) Stapf, commonly known as African custard apple, is a tree species native to tropical Africa. It has medicinal properties and is used in traditional medicine for treating various ailments. Additionally, it is a valuable source of food and has many nutritional benefits.Light Requirements
Pleiocarpa pycnantha requires a lot of bright light to grow and thrive. The plant does best in direct sunlight, but it can also grow in partial shade. It is essential to ensure that the plant receives at least six hours of direct sunlight per day to prevent stunted growth and yellowing leaves.
Temperature Requirements
The optimal temperature for Pleiocarpa pycnantha growth is between 18 and 25 °C. However, it can tolerate temperatures as low as 10°C. The plant is not frost-tolerant and will start to decline if exposed to temperatures below 3°C. It is, therefore, essential to keep the plant in an environment with stable temperatures and protect it from extreme temperature fluctuations.
Soil Requirements
Pleiocarpa pycnantha grows best in well-draining soil that is rich in nutrients. The soil should be slightly acidic with a pH range of 5.5 to 6.5. The soil should also be mixed with organic matter such as compost or manure to improve fertility. It is important to ensure that the soil stays moist, but not waterlogged, as overly wet conditions can cause root rot.
Cultivation Methods
Pleiocarpa pycnantha is an evergreen shrub that requires a warm climate to thrive. It is best planted in sandy or well-draining soils that are rich in organic material. The plant needs adequate sunlight, but it must be protected from strong winds. During propagation, use stem cuttings that can grow roots easily in moist soil.
Watering Needs
The plant needs frequent watering, especially during hot and dry weather conditions. Drought-stressed plants may drop their leaves, reducing their growth potential. However, it would help if you avoided overwatering the plant to prevent root rot, which may cause leaf wilting and death of the plant. The best approach is to keep the soil moist by regularly watering the plant, but allow it to dry out partially before repeating the process.
Fertilization
Adequate fertilization encourages healthy growth in Pleiocarpa pycnantha. It would help if you used a slow-release, balanced fertilizer that contains all the necessary nutrients in the right amounts. Apply the fertilizer early in the growing season and again in the middle of the season to promote good health. Avoid using high nitrogen fertilizers, as they encourage vegetative growth at the expense of flowers and fruits.
Pruning
Pruning helps to keep the plant in shape, promote bushy growth, and enhance the development of flowers and fruits. It is essential to prune the plant regularly, especially after flowering, to remove dead or weak branches. This practice stimulates new growth, which gives the plant a compact and healthy appearance. Cut back overgrown branches, and thin out crowded areas to allow sunlight and air circulation into the center of the plant.
Propagation of Pleiocarpa pycnantha (K.Schum.) Stapf
Pleiocarpa pycnantha (K.Schum.) Stapf, also known as the African peach or Mukanya kude, is a species of tree native to Africa. The tree is commonly propagated through seeds, stem cuttings, and grafting.
Propagation through Seeds
Seeds are the most common method of propagation for Pleiocarpa pycnantha. The seeds should be collected from ripe fruits, which are usually yellow or orange in color. After collection, the seeds should be cleaned, dried, and stored in a cool, dry place until planting.
When planting, the seeds should be sown in a well-draining potting mix and covered with a thin layer of soil. The pot should be kept in a warm, humid area until germination, which typically takes around 2-4 weeks. Once the seedlings have emerged, they should be gradually acclimated to normal growing conditions.
Propagation through Stem Cuttings
Pleiocarpa pycnantha can also be propagated through stem cuttings. Cuttings can be taken from young, healthy stems in late spring or early summer. The cuttings should be around 6-8 inches in length and should have at least one set of leaves.
The lower leaves on the cutting should be removed, and the cutting should be dipped in rooting hormone. The cutting should then be planted in a well-draining potting mix and kept in a warm, humid area until roots have formed, which typically takes around 4-6 weeks.
Propagation through Grafting
Grafting is another method of propagation for Pleiocarpa pycnantha. It involves joining a stem cutting or scion from the desired tree to a rootstock from a different, but compatible tree.
The scion should be taken from a young, healthy stem and should be around 6-8 inches in length. The rootstock should also be selected carefully to ensure compatibility. The two parts should be joined together using a grafting knife and then secured with grafting tape.
The grafted tree should be kept in a warm, humid area until graft union has formed, which typically takes around 4-6 weeks. After union has formed, the tree should be gradually acclimated to normal growing conditions.
Disease Management
Pleiocarpa pycnantha is susceptible to various fungal diseases such as leaf spots, stem cankers, and root rot. The following are some ways to manage these diseases:
- Fungicides: Apply fungicides to the foliage or soil as directed by the manufacturer to prevent fungal growth and spread.
- Sanitation: Remove and destroy infected plant parts as soon as possible to prevent the spread of the disease.
- Cultural practices: Practicing good cultural practices such as proper watering, fertilization, and avoiding overcrowding will keep the plant healthy and resistant to diseases.
Pest Management
Pleiocarpa pycnantha is susceptible to pests such as scales, spider mites, and mealybugs. The following are some ways to manage these pests:
- Insecticides: Use insecticides as directed by the manufacturer to kill and prevent the spread of pests.
- Beneficial insects: Encourage the presence of beneficial insects such as ladybugs, lacewings, and parasitic wasps as they feed on pests.
- Manual removal: Physically remove pests such as scales and mealybugs using a soft brush or cloth.
