Propagation of Chrysophyllum millenianum Engl.
Chrysophyllum millenianum Engl., also known as Star Apple or Caimito, is a fruit tree native to the Caribbean. The plant is mainly propagated by seeds, but it can also be propagated through cuttings and grafting.
Seed propagation
Seed propagation is the most common method used in propagating Chrysophyllum millenianum. The seeds can be obtained from ripe fruits, and they are usually planted immediately or kept in a moist environment until planting.
The seeds are planted in a well-draining soil mixture, and they should be kept moist. The seeds usually germinate within 14 days, and they can be transplanted to their permanent location when they have grown to a height of 3-4 inches.
Cutting propagation
Propagation of Chrysophyllum millenianum using cuttings involve collecting stem cuttings from healthy plants and planting them in rooting mediums such as sand or well-draining soils. The cuttings should be about 6 inches long, and they should be planted in the medium at a depth of about 2-3 inches.
The cuttings are usually treated with a rooting hormone to stimulate root growth, and they should be kept moist until they start to develop roots. The rooted cuttings can be transplanted to their permanent location when they have developed a good root system.
Grafting propagation
Grafting is another method used in propagating Chrysophyllum millenianum. It involves taking a scion from a healthy plant and attaching it to a rootstock from another Chrysophyllum millenianum plant.
The scion is usually taken from a plant with desired characteristics such as specific fruit quality or growth habit. The graft is usually made using a cleft graft or whip and tongue graft.
The grafted plant should be kept moist, and it should be protected from direct sunlight until it has established. The grafted plant can be transplanted to its permanent location when it has established itself.
