Propagation of Dendrobium Brachycarpum A.Rich.
Dendrobium brachycarpum A.Rich., commonly known as the Short-Fruited Dendrobium, is a species of orchid native to Southeast Asia, particularly found in countries such as Thailand, Laos, and Vietnam. Orchid enthusiasts cultivate this species for its attractive flowers and easy propagation.
Propagation Methods
The plant can be propagated both sexually and asexually.
Sexual Propagation
The sexual propagation of Dendrobium brachycarpum involves the collection of seeds from mature fruits of healthy parent plants. The seeds are sterilized and sown on a suitable medium such as an agar or coconut husk mix. The seeds need to be kept in a warm, humid environment, and regular watering is required to ensure that the medium remains moist. Germination occurs within three to six weeks, and the seedlings can be transferred to pots within six months of germination. This method of propagation is time-consuming, and the plants may take up to five years to reach maturity and produce flowers.
Asexual Propagation
The asexual propagation of Dendrobium brachycarpum is a quicker method that involves the production of plantlets from various parts of the parent plant. Some common asexual propagation methods include:
- Division: The parent plant is separated into two or more sections, each with roots attached. The divided sections are then planted into individual pots.
- Backbulbs: Backbulbs are old pseudobulbs that have stopped producing leaves. These can be separated from the parent plant and planted to produce new growth.
- Keikis: Keikis are plantlets that grow on the flowering stem or along the aerial roots of the parent plant. They can be removed and potted once they grow roots and are large enough to survive on their own.
Asexual propagation ensures that the offspring are genetically identical to the parent plant and can produce flowers within two to three years.
