Do bananas have seeds? Where is it? Reproduction by what?
Banana is the most common fruit in our life, and it is also a very popular fruit. But unlike other fruits, when we eat fruits such as peaches, plums, apples, apricots and so on, we will find seeds in these fruits, but only bananas do not see where the seeds are. Do bananas have seeds? Where? How do you breed?
As a plant that will blossom and bear fruit, bananas should of course have seeds. In fact, it is not that bananas have no seeds, we often see some wild bananas with a large number of seeds, but this kind of wild bananas with many seeds can not be eaten. But we often eat bananas, but rarely see seeds, it is not that this kind of bananas have no seeds, but the seeds of bananas have been degraded, if we look carefully, we can see that there are degraded seeds in the middle of bananas. so bananas are not without seeds, but because the seeds are undeveloped.
Wild bananas have seeds, of course, there is no problem with their reproduction, but the bananas we eat have no seeds, what do we rely on to breed, why are there no seeds? Experts who study bananas explain that tens of thousands of years ago, bananas in Southeast Asia had genetic mutations that changed from two copies of each chromosome to three, so that their seeds could not develop. Since then, this kind of banana has become regardless of men and women, from sexual reproduction to asexual reproduction.
But this kind of banana without seeds has become the delicacy of human beings. When someone found this edible banana, it was planted on a large scale by various ways of asexual reproduction, and since then, the distribution of bananas has been continuously expanded. It is precisely because the mode of reproduction of banana is asexual reproduction, there is no natural spread of seeds, and can only be cultivated artificially, so its distribution is not wide. Therefore, some people are worried about the situation of bananas regardless of men and women, thinking that bananas may become extinct under the threat of diseases and insect pests.
Speaking of which, I believe you should know how bananas breed. There are mainly the following ways:
1. Tuber propagation
That is to say, the underground rhizome of banana is cut into pieces for propagation. The specific method is to cut the tuber into small pieces with strong buds, then apply plant ash on the section to prevent corrosion, put the bud eyes up on the border surface according to a certain plant spacing, cover with a layer of soil, cover with straw, strengthen management, apply fertilizer in time, prevent diseases and insect pests, and transplant when it grows to about 50 centimeters. This method is the most efficient way for banana reproduction and can produce a large number of buds in a short period of time.
Second, sucking bud ramet
Bananas that are about to grow new buds are cut and transplanted from the mother plant, this method is a common way of cultivation, but the efficiency is not high, it is difficult to cultivate a large number of seedlings in a short time. The specific method is to cut the new bud from the mother plant with a tool, reduce the injured root, smear the wound with plant ash, and transplant it to the finished border surface.
III. Tissue culture
The above two methods are more traditional ways of cultivation and reproduction, while tissue culture is a newly invented breeding technology under the condition of modern science and technology. That is, under aseptic conditions, a small part of the tissues of stem tips, roots, leaves, flowers and fruits of bananas are cultured in an artificially controlled environment to regenerate and form complete plants. The biggest advantage of tissue culture technology is that a large number of disease-free and high-quality seedlings can be produced in a relatively short time. If a banana line with good quality and high yield is found in production, by using tissue culture technology, a large number of healthy and strong seedlings with disease-free, pure germplasm and uniform specifications can be produced in a relatively short time, and the excellent characters of the original variety can be maintained.

For corn post-seedling herbicides, corn growers use them every year, but every year there will be problems such as corn drug damage and no effect after beating, and sometimes there will be herbicides after beating corn seedlings. The weeds have not died, but the corn has died, especially for farmers.
