Propagation of Glycine Moniliformis Hochst. ex A.Rich.
Glycine moniliformis Hochst. ex A.Rich., commonly known as the Moniliform glycine or the Stick glycine, is a perennial woody legume. The plant is native to Africa and it is commonly grown for its edible roots, forage, and timber. Propagation of Glycine moniliformis can be carried out through seeds or vegetative means.
Propagation through Seeds
The most common method of propagating Glycine moniliformis is through seeds. The seeds should be obtained from mature pods of healthy plants. Seeds should be scarified to aid in their germination as they have a hard seed coat which might prevent water uptake. It is recommended to soak the seeds for up to 24 hours to soften the seeds. Sowing should be done at the onset of the rainy season when there is enough moisture in the soil. The seeds should be sown at a depth of 1-2 cm and spaced at a distance of 0.5 m between plants and 1.5 m between rows. Upon germination, the seedlings should be thinned to leave only one plant per hole.
Propagation through Vegetative Means
Glycine moniliformis can also be propagated vegetatively through stem cuttings and root suckers. Stem cuttings should be obtained from healthy mature stems. The stem cuttings should be about 20-30 cm long and stripped off all the leaves except the apical leaves. The cuttings should be treated with rooting hormone and planted in well-drained soil. The soil should be kept moist until the cuttings develop roots. Root suckers, which are shoots that arise from the base of the stem, can also be detached and planted to propagate more plants.
Glycine moniliformis Hochst. ex A.Rich. has both sexual and asexual propagation methods. Propagation through seeds provides genetic diversity, while vegetative propagation ensures that the propagated plants are the same as the mother plant. Farmers can choose the most appropriate method of propagation depending on the resources available and their needs.
