Propagation of Mimosa biglobosa Jacq.
Mimosa biglobosa Jacq., also known as "gum Arabic tree", is a multi-purpose plant commonly found in Africa. It is used for different purposes, such as medicine, food, and timber. The plant can be propagated through various methods, including seeding, cuttings, and air layering.
Seeding
Seeding is the most common method of propagation for Mimosa biglobosa Jacq. The seeds are easily collected and germinate rapidly. The seeds should be collected from mature pods when they turn brown and dry. The seeds should be soaked in water for 24 hours before planting. The seeds should be planted in seed beds or nursery bags filled with sandy soil. The seeds should be planted at a depth of 2-3 cm and should be watered daily. The seeds should germinate within 1-2 weeks, and the seedlings should be transplanted to the field after 4-6 weeks.
Cuttings
Cuttings can also be used to propagate Mimosa biglobosa Jacq. The cuttings should be taken from healthy and mature trees during the rainy season. The cuttings should be about 15-20 cm long and should be taken from the tree's lower branches. The cuttings should be dipped in a rooting hormone and planted in a rooting medium such as sand, soil, or vermiculite. The cuttings should be watered regularly and kept in a warm and humid environment. The cuttings should root within 4-6 weeks, and the rooted cuttings should be transplanted to the field after 4-6 weeks.
Air Layering
Air layering is another method of propagating Mimosa biglobosa Jacq. This method involves cutting a branch halfway through and wrapping it with a moist rooting medium such as sphagnum moss or vermiculite. The wrapped branch should be kept moist and covered with a plastic bag to maintain humidity. Roots should start to grow after 6-8 weeks, and the rooted branch should be cut off and transplanted to the field after 6-8 weeks.
