What are the propagation methods of West Indian cherries? Planting time of West Indian Cherry cutting method

West Indian cherries are planted in fields, containers or gardens as seedlings. There are four propagation methods of seedlings: cutting, sowing, air striping and grafting. What are these four methods? Let's have a look!

Because of the shortcomings of single pseudo-fruiting habit, unsubstantial seeds, low germination rate, large genetic diversity, irregular seedlings and late fruiting age, sowing method is generally more commonly used than cutting method or air striping method. however, although the air striping method is easy to take root, but there are great differences among different varieties, and mass propagation is more time-consuming and time-consuming, the cutting method is still the simplest and most successful, and can preserve the fine characteristics of parents.

I. sowing method

After harvest, the West Indian cherry was crushed to remove the core, washed with water and dried in a cool place for 1-2 days before sowing. When sowing, the kernels were sowed directly in a shallow basin or 72 holes, and germinated about 10 to 30 days after sowing. The germination was faster in the high temperature period and very slow in the low temperature period. When the seedlings grow to 5-10 cm, then transplant them into a plastic soft basin. West Indian cherry seeds germinate easily but not neatly, and the seeds produced by some plants often lack viable embryos, and the germination rate is often less than 30%.

2. Cutting method

During the growth period from March to October, half-ripe healthy branches were selected, with a diameter of 0.7-1.2 cm, a length of 15-20 cm, and attached 4-6 leaves, which were inserted into river sand, vermiculite or peat soil or several mixtures were suitable for cooperative seedling bed medium. Cuttings should especially be kept moist and shaded. Rooting agent (IBA) can be used to promote hairy roots. The roots took root about 1.5 ~ 2 months after cuttage, and then transplanted after the root group grew vigorously. If the cutting method is managed properly, the survival rate will be 60-90%, especially in March or October. The rooting rate of sour species was significantly higher than that of sweet species.

3. Strip pressing method

In the use of horticultural techniques, striping is the fastest way to cultivate big trees, but the effect of West Indian cherry varieties is very different. Chen Bohui (1997) aimed at 10 sour species and 10 sweet species in Yunlin branch field of Tainan field, wrapped with water moss, wrapped with plastic cloth, and applied tightly up and down, the results showed that the sour species had 80% rooting rate one month after pressing, while the grafted sweet species only showed no Callus after 3 months of experiment.

In general, seedling producers who engage in striping breeding are striped during the growth period from March to October, cut off and planted in a soft basin container when the roots are complete after 2 to 4 months, and then moved into the field or pot planting in March to April of the next year.

IV. Grafting method

Abdominal grafting and splicing can be used, but it is seldom used.
