Propagation of Heritiera littoralis Dryand.
Heritiera littoralis Dryand., commonly known as the looking-glass mangrove, is a coastal species that belongs to the family Malvaceae. Propagation of Heritiera littoralis Dryand. can be done through various methods. The following are some of the propagation methods that can be used for this plant:
Seed propagation
Seeds are an easily accessible and viable option for the propagation of Heritiera littoralis Dryand. The seeds can be collected from the mature fruits of the plant. Before sowing, the seeds should be washed with clean water to remove any excess pulp that may hinder germination. The seeds must be sown within a day of collection, as they typically do not remain viable for long. Sow the seeds in a seedbed that is well-draining and contains a mixture of sand and soil. After sowing, keep the soil moist and under partial shade to avoid any potential sun damage.
Vegetative propagation
Heritiera littoralis Dryand. can be vegetatively propagated by cuttings or air layering. Cuttings are the safest to use, as air layering may cause damage to the parent plant. Choose a healthy stem or shoot from the parent plant and cut it into 15–20 cm long sections. Remove any leaves from the lower third of the cutting and dip the cut end into the rooting hormone. Insert the cutting into a rooting medium that is well-draining and keep it under partial shade. Keep the soil moist and water when necessary.
Grafting
Grafting is not a common propagation method for Heritiera littoralis Dryand., but it is still possible. The plant can be grafted onto a rootstock that is resistant to common diseases or pests. The selected rootstock should be healthy and disease-free. The scion, or plant that will be grafted onto the rootstock, should come from a healthy plant and be compatible with the rootstock. Grafting is best done during the plant's dormant season, typically in late autumn or early winter. After grafting, the plant should be kept under humid conditions and in partial shade until it begins to show new growth.
