Propagation of Heterotis segregata Benth.
Heterotis segregata Benth. is a plant species commonly found in tropical Africa. It is known by various common names, including cedrela, Senegal oak, and African teak. It is a tree species that is commonly propagated through seeds and vegetative means.
Propagation by Seeds
The seeds of Heterotis segregata Benth. can be collected directly from the plant or purchased from reputable nurseries. The seeds are then planted in a well-draining soil mix, and the containers are kept in a warm and humid environment. Germination typically occurs within 2-4 weeks.
It is important to note that the seeds of Heterotis segregata Benth. have a short viability period. Therefore, it is recommended to sow the seeds as soon as possible after collection or purchase.
Propagation by Cuttings
Heterotis segregata Benth. can also be propagated through cuttings. Softwood or semi-hardwood cuttings are taken from the parent plant during the growing season. The cuttings should be approximately 10-20 cm long and have a diameter of 0.5-1 cm.
The cuttings are then placed in a well-draining soil mix and covered with a plastic bag to create a humid environment. The containers should be kept in a warm and bright area, but not in direct sunlight. Rooting typically occurs within 2-3 weeks.
It is important to ensure that the cuttings do not wilt during the rooting process. Therefore, they should be misted regularly, and the soil should be kept moist but not waterlogged.
