Pruning should be done selectively to avoid damaging the plant and should aim to remove about a third of the plant's growth each year.
Propagation of Dalbergia ochracea Harms
Dalbergia ochracea Harms, commonly known as the Ochraceous Dalbergia, is a plant species native to Cameroon, Gabon, and the Republic of Congo. This species is a valuable timber tree, used for making furniture, construction, and musical instruments. Propagation of this plant can be done through several methods:
Seed Propagation
Seed propagation is the most common method for propagating Dalbergia ochracea Harms. The seeds are collected from mature fruits and then stored in a cool, dry place until planting. Before sowing, the seeds should be scarified or stratified to enhance germination. Scarification is done by mechanically scratching the seed coat, while stratification involves cold treatment in a moist medium. After treatment, the seeds are planted in a well-draining medium and kept under appropriate environmental conditions until germination.
Cuttings Propagation
Cuttings propagation involves taking stem cuttings from the parent plant and rooting them in a suitable medium. Softwood, semi-hardwood, or hardwood cuttings can be used for propagation. Softwood cuttings are taken during the growing season, while hardwood cuttings are taken in winter when the plant is dormant. The cuttings are treated with a rooting hormone and planted in a sandy medium. They are then kept under high humidity and monitored for growth.
Air layering Propagation
Air layering propagation is a method of vegetative propagation that involves inducing roots on a stem while the plant is still attached to the parent plant. A ring of bark is removed from the stem, and the exposed area is treated with a rooting hormone. A moist medium is then wrapped around the treated area and covered with plastic to maintain high humidity. After a few weeks, roots will develop, and the stem can be cut off and planted in a suitable medium.
In conclusion, Dalbergia ochracea Harms can be propagated through seed, cuttings, and air layering. Each method has its advantages and disadvantages, and the choice of which method to use depends on various factors such as the availability of planting material, time of year, and desired outcome.
