Propagation of Strychnos micans S.Moore
Strychnos micans S.Moore is a woody vine species. Propagation of Strychnos micans can be done in various ways such as by seeds, cuttings, layering, and grafting.
Propagation by seeds
Seeds of Strychnos micans S.Moore are generally used for propagation. The seeds are collected from the mature fruits. After collection, the pulp is removed by washing the seeds in water. The cleaned seeds are sowed in a nursery bed filled with well-drained soil. The seeds should be sowed at a depth of 1 to 2 cm. They should be watered regularly and protected from direct sunlight. Germination of seeds starts within 2-3 weeks, and after one year, seedlings are ready for transplanting.
Propagation by cuttings
Propagation by cuttings is a common method for Strychnos micans. This method is commonly used in countries like India, where the species occurs naturally. Healthy and matured stem cuttings of 15 to 20 cm in length with three to four nodes are collected at the beginning of the rainy season. The cuttings should be treated with a rooting hormone to stimulate rooting and then planted in a rooting medium of soil, sand, and compost. The cuttings should be watered regularly, and in about 4 to 6 weeks, roots start to develop, and the plant is ready for transplanting.
Propagation by layering
Propagation by layering is another method for Strychnos micans S.Moore. In this method, matured stems are bent and buried partially in a prepared rooting medium of soil and sand. The portion buried should be wounded and treated with a rooting hormone to stimulate rooting. When the roots have developed, the new plant can be separated and transplanted into a new bed.
Propagation by grafting
Grafting is another method of propagation. This method is used for the propagation of desired cultivars of Strychnos micans and also to enhance the growth of the plant. The most common method used for grafting is cleft grafting. In this method, the scion should be selected from the disease-free, pest-free, and healthy mother plants. The scion is then grafted onto the rootstock of the same species. The grafted plant is wrapped with plastic sheets, and after about two weeks, it is unwrapped to check the union of the scion with the rootstock.
