Propagation of Angraecopsis thouarsii auct.
Angraecopsis thouarsii auct. is a beautiful epiphytic orchid species that can be propagated by several methods. Here are some techniques that can be used to propagate Angraecopsis thouarsii auct:
Division
The easiest and most common method of propagating Angraecopsis thouarsii auct. is by division. This is usually done during repotting, preferably in the spring. Divide the plant by cutting the rhizome into sections, ensuring that each section has at least one healthy pseudobulb and several healthy roots. Then plant each section in a suitable potting mix in separate pots.
Meristem culture
For mass propagation, meristem culture can be used to produce virus-free plants. Take small pieces of plant tissue containing meristematic cells, which are fast-growing, undifferentiated cells capable of developing into any type of plant tissue. These pieces are grown on a nutrient medium containing growth hormones and other nutrients, which encourages the development of new plants. The plants that develop from meristem culture are clones of the parent plant and are genetically identical.
Keiki propagation
Keikis are small plantlets that grow from the nodes of the stem or the base of the plant. Angraecopsis thouarsii auct. may produce keikis naturally or they can be induced by wounding the stem. Keikis can be removed from the mother plant once they have developed their own roots and leaves. Plant them in their separate pots and care for them until they grow into mature plants.
Overall, propagation of Angraecopsis thouarsii auct. is not too difficult and can result in a collection of beautiful orchid specimens.
