Propagation of Solanum dasyphyllum Schumach. & Thonn. var. inerme Bitter
Solanum dasyphyllum Schumach. & Thonn. var. inerme Bitter, commonly known as African eggplant, is a perennial plant that is grown for its fruit and leaves. It is primarily propagated by seeds, but can also be propagated by vegetative methods.
Propagation by Seeds
The seeds of Solanum dasyphyllum Schumach. & Thonn. var. inerme Bitter are the primary method of propagation. The seeds are small and black and can be collected from mature fruits. To propagate from seeds, the seeds are first cleaned and then sown in seedbeds or nursery trays filled with a well-draining soil mix. The seedbeds or trays should be kept moist and in a warm, shaded area until germination occurs, which usually takes 10-14 days.
Vegetative Propagation
Solanum dasyphyllum Schumach. & Thonn. var. inerme Bitter can also be propagated by vegetative methods, such as stem cuttings and division. Stem cuttings should be taken from mature plants in the early morning or late afternoon when the temperatures are cooler. The cuttings should be approximately 10-15 cm in length and should have at least 3-4 nodes. The cuttings should be dipped in a rooting hormone and then planted in a well-draining soil mix. The cuttings should be kept moist and in a warm, shaded area until they root, which usually takes 2-3 weeks.
Division is another method of vegetative propagation. It involves dividing an established plant into smaller sections and then planting the sections in a new location. The plant should be carefully dug up and then divided into smaller sections, making sure that each section has a good amount of roots. The sections can then be planted in a well-draining soil mix in a new location.
