Propagation of Calypogeia sullivantii Austin
Calypogeia sullivantii Austin is a liverwort plant that can be propagated both sexually and asexually. In the wild, this plant reproduces through spores, but it can also be propagated through vegetative means in cultivation.
Asexual propagation
Asexual propagation of Calypogeia sullivantii Austin can be achieved through vegetative propagation using gemmae. Gemmae are small, multicellular structures produced by the plant that are capable of growing into a new plant. They are typically found in the cups of the plant’s thallus and can be easily separated for propagation.
To propagate the plant using gemmae, first, carefully remove the gemmae from the thallus using a pair of tweezers. Place the gemmae onto a suitable growing substrate, such as moist soil or peat moss. Keep the substrate moist and warm, ideally around 25°C, and the gemmae will soon start to grow into new plants.
Sexual propagation
Calypogeia sullivantii Austin can also be propagated through sexual means using spores. The spores are produced by the mature plants and can be collected for propagation.
To collect the spores, harvest the mature plant and allow it to dry. Once the plant is dry, shake it gently over a sheet of paper to release the spores. The spores can then be collected and sown onto a growing substrate. Cover the substrate with a clear plastic bag to create a humid environment, and keep it in a warm and bright location. The spores will germinate and grow into new plants over time.
