Propagation of Carapa gummiflua C.DC.
Carapa gummiflua C.DC., commonly known as Andiroba, is a tropical rainforest tree originating in South America. The tree is acknowledged for its medicinal and commercial values. Propagation methods for Andiroba include both sexual and asexual methods.
Sexual Propagation
Andiroba can be propagated by seed. The fruit of the Andiroba tree contains seeds that can be extracted and sown directly into the soil. Before sowing, the seeds need to be cleaned and dried in the sun or low-temperature dryers to prevent fungal infections. The seeds should be sown at a depth of 5-10 cm, and the soil must be kept moist. The germination of seeds takes around 15-45 days.
Asexual Propagation
Andiroba can be propagated asexually through vegetative propagation. The plant can be propagated using cuttings or by air layering.
Using stem cuttings, select a healthy stem and cut 10-15cm of the stem with mature leaves. Remove the lower leaves and dip the cuttings in rooting hormones. Plant the cutting in a pot with well-draining soil and water thoroughly. Cover the cutting with a plastic bag or dome to retain moisture and increase the humidity.
Air layering is another asexual propagation method. Select a healthy branch around 1-2cm in diameter and strip the bark off a section of its mid-portion. Wrap the bark-less section with moist sphagnum moss and apply rooting hormones. Cover the moss with a plastic wrap and tie both ends of the wrap with a string to secure the moss in place. The root formation will take 2-3 months, and the new plant can be cut off and transplanted into the soil.
In conclusion, Andiroba, or Carapa gummiflua C.DC., can be propagated by both sexual and asexual propagation methods. Seed germination, stem cutting, and air layering are popular methods of propagation for this tree species.
