West Indian cherry is an evergreen shrub or can be pruned and cultivated to form a small tree. It can grow up to 4.5 meters in height from 10 to 12 years old. The leaves are opposite, and the leathery material is smooth. It is obovate to oblong and full. , 3--10cm long, petiole is very short, its shape, size, species are different, scattered inflorescence, small 5-flowered, usually pink, red and white flower system, the fruit is a berry, the shape of cherries, However, there are three shallow grooves into three petals, mature orange red and purple, the skin is thin and easy to damage, there are three seeds each containing a seed. Breeding 1. Spontaneous Biochemistry After the West Indian cherry is harvested, the skin of the peel is cut to remove the core, and the flesh outside the attached core is washed away with fresh water, and then placed in the shade to dry for 1-2 days. . The seeds were sown directly in shallow basins and sowed about 10-30 days after sowing. When the seedling grows to 5 - 10 cm, it is transplanted into a plastic soft pot. West Indian cherry seeds germinate easily, but their germination is not neat and some plants produce seeds that often lack viable embryos and germination rates are often below 30%. 2. Cuttage method During the growth of Chunxia, ​​select semi-mature and robust shoots, 0.7--1.2 cm in diameter, each length 15--20 cm, epiphytes 4--6 leaves, inserted in river sand, vermiculite or Peat soil or several mixtures are suitable for seedbed media. Cuttings need to be kept moist and shaded. Rooting agent (IBA) treatment can be used to promote hair rooting. About 1.5--2 months after cuttings, hairy roots were developed and the roots grew vigorously before transplantation. If the cutting method is properly managed, there will be a 60--90% survival rate. 3, the pressure layer method in the use of horticultural technology, layering method is a method of rapid growth in the tree, but the effect of the West Indian cherry varieties vary greatly. During the spring of last year, the author focused on the existing sour and sweet varieties of the field, wrapping them with water moss on a circular peeling method, wrapping the plastic cloth, and tightening it up and down. The results showed that the sour flavor was applied to the bead. Eighty percent of hairy rooting rates occurred one month after treatment, while sweet-smelling species only emerged from healing tissue after 3 months of testing. The above describes the main breeding methods of West Indian cherry. Although the air layering method is easy to root, but the effect varies greatly between breeds and the procedure is more complicated when it is mass-produced. It is usually used less frequently. The age of the actual birth method is relatively late, and the quality variation among the seedlings is large. Therefore, the cutting method is generally used most often. Simple and easy to succeed.
