What is the reason for this phenomenon? How to solve it? Let me share it with you.
The stone of a peach, why will it bear peach after going down?
We can choose two methods when fruit trees propagate. The first method is to sow their seeds, wait for the seeds to germinate and harvest their next generation. The second method is to tie a branch of the fruit tree, cut off the bark, expose the xylem, and then wrap it with soil. When the roots grow in the mud bag, cut them down and plant them. Or directly cut off the branches of a fruit tree and insert them in the soil, and the branches will give birth to roots and become new fruit trees.
For these two different fruit tree propagation methods, the results are also different.
The second method is botanically called asexual reproduction. What is asexual reproduction? Simply put, it is to directly reproduce a certain tissue of the mother tree into a new plant, rather than pollinating the fruit.
As for pollinating the fruit of the female flower by the pollen of the male flower, and then sowing it with the stone, this is called sexual reproduction. However, sexually propagated peaches cannot perfectly inherit the quality of the peach mother tree.
Therefore, it is variable to plant a new peach tree with peach seeds. This variation is usually more likely to be atavism, that is, naturally occurring peach varieties become hairy peaches.
Peaches are planted with peach seeds. How to change this situation and make it bear peaches again?
Although peach trees planted with peach kernels bear peaches, it does not mean that there is no way to change this situation. We can use another method, which is grafting. Grafting can be used not only on young peach trees, but also on fruit-bearing peach trees. After the grafting survives, the peaches can bear fruit.
This method is called multi-head grafting, and fruit farmers will do this job when they are not satisfied with the fruit varieties produced by peach trees. To accomplish this task, there must be several peach scions. Scions can be purchased, or you can plant peaches and pick a few branches to graft.
Scions must grow vigorously, without pests and diseases, and have pure varieties. If the variety is not pure, it loses the meaning of grafting. The scion should be sealed with wax after collection to prevent water loss and affect the survival rate of grafting. The graf method can be carried out by conventional graf.
Cut off the fruiting branches of the peach, cut the scion into 3~4cm long faces, cut off the back of the long faces, and then cut a short face. Then cut the smooth bark of the rootstock longitudinally with a knife to expose xylem, insert the scion into the cambium facing the rootstock, leaving 0.5cm of exposed white, and then tie it tightly with grafting tape to prevent rainwater from entering.
After the grafting is completed and the scion germinates, the peach that will bear fruit in the future is the peach. If the rootstock of peach trees is thick, it can also be split, and more scions can be inserted into one rootstock.
To sum up, it is normal for peach trees planted with peach seeds to bear peaches. Because most fruit trees are propagated by seed nuclei, the fruit will have atavistic variation. This phenomenon can be changed by grafting.
