Propagation of Alectryon macrococcus Radlk. var. auwahiensis G. Linney
Alectryon macrococcus Radlk. var. auwahiensis G. Linney, commonly known as Hawaiian mahogany or maua, is an indigenous plant species in Hawaii. It is a small tree or shrub that belongs to the soapberry family (Sapindaceae). It is an endemic species that can be found in dry to mesic forests and shrublands on the islands of Maui and Molokai.
Propagation of A. macrococcus can be done through various methods, including:
Seed propagation
Seeds of A. macrococcus can be collected from mature fruits. Ripe fruits are usually yellowish-orange and have a soft and fleshy outer layer. The seeds inside are typically hard and dark-colored. The seeds should be thoroughly cleaned and scarified before planting to break their tough outer seed coat and enhance germination.
The scarified seeds can be sown in well-draining potting soil and placed in a warm and humid environment. The soil should be kept moist, and the seedlings should be protected from direct sunlight. Germination can take up to several weeks to a few months.
Cuttings propagation
A. macrococcus can also be propagated from stem cuttings. Softwood cuttings taken from young and healthy plants are preferable. The cuttings should be treated with a rooting hormone and placed in a sterile and well-draining rooting medium. The medium should be kept moist and covered with a plastic bag to maintain high humidity. The cuttings can root within a few weeks to a few months.
Grafting propagation
Grafting can also be used to propagate A. macrococcus. It involves joining a scion (a part of the desired plant) with a rootstock (a different plant of the same or closely related species). This method is useful for perpetuating desirable traits and maintaining genetic diversity.
The scion is usually taken from a healthy and mature A. macrococcus tree, while the rootstock can be from a closely related plant species in the same family. The two parts are joined by making a cut in the rootstock and inserting the scion into it. The grafted plant should be kept in a warm and humid environment and protected from direct sunlight until new growth appears.
