Propagation of Teramnus micans (Baker) Baker f.
Teramnus micans (Baker) Baker f. is a fast-growing, perennial plant that belongs to the Fabaceae family. It is commonly known as velvet bean, Madagascar bean, Bengal bean, and pea, and it is native to Madagascar but now widespread in tropical and subtropical regions worldwide. Propagation of Teramnus micans can be done using several methods.
Seed Propagation
One of the easiest methods of propagation is seed propagation. Seeds of Teramnus micans are easy to collect from mature pods of the plant. The pods should be allowed to dry on the plant before harvesting to ensure that the seeds have fully matured. Once harvested, the pods can be left to dry completely at room temperature. The seeds can be removed by gently pressing the pods or by threshing the pods by hand. Once the seeds are obtained, they can be stored in a cool, dry place for later use or planted directly.
The best time to plant Teramnus micans seeds is during the rainy season. The seeds can be sowed in pots or seedbeds. Before planting, the soil should be turned over, and organic matter should be mixed in to improve soil fertility. The seeds should be planted at a depth of 2-3 cm and covered with soil. The seeds should be kept moist, and germination occurs within 7-10 days.
Cutting Propagation
Propagation can also be done using stem cuttings. Cuttings are taken from the mother plant and placed in suitable rooting media. The best time to take cuttings is during the rainy season when the plant is actively growing. The cuttings should be taken from healthy branches that are about 10-15 cm long and have at least two nodes.
The cuttings should be dipped in rooting hormone powder and planted in a well-draining soil mix. The cuttings should be planted at a depth of 1-2 cm and misted regularly to keep them moist. Roots should develop within 2-3 weeks, and the new plants can be transplanted to larger pots or directly into the ground.
