Where are the banana seeds?

1. The seeds of banana have been degraded by artificial breeding. Now there are darker parts in the middle of the bananas. That's the trace of degenerated banana seeds. Wild bananas will have a hard seed. Banana, which originated in Asia, Malaysia and southwest China, is one of the oldest cultivated fruit trees in the world. Today's banana cultivation originated from wild pointed-leaf bananas and long-stalked bananas.

2. Where are the banana seeds? Back to the banana seed in the fruit, cut the white pulp will find a brown dot in the middle, this is its seed. But now its seeds are very small and improved, and the taste will not be affected when eaten. Wild bananas will have a hard seed.

3. There is a hard seed in the original wild banana, which is extremely inconvenient to eat. Through long-term cultivation and selection, wild bananas have been mutated and there are no seeds in the fruit. In fact, strictly speaking, bananas are not without seeds. If you look carefully, the rows of brown dots inside the banana are degenerated seeds.

4. At present, there are wild bananas in Southeast Asia or Africa, and wild bananas normally have seeds. As long as you put aside the wild bananas with high maturity, you can see some brown to black hard-shell seeds clearly in the pulp. These seed types show quasi-circle, quasi-ellipse or quasi-cuboid characters, and there are also great differences in size. The small banana seed is about three millimeters, and the big banana seed is about 5cm.

5. There are seeds. Banana seeds are located at the top of the fruit (that is, bananas they usually eat). Banana seeds lack endosperm and are difficult to germinate into banana trees. The position is relatively hidden and is not easy to be observed. In wild bananas, you can see granular seeds in the fruit. However, due to long-term manual selection and cultivation, today's commercial banana varieties have almost no seeds.

6. In fact, bananas have seeds. Before bananas and now wild bananas have seeds, which are in the pulp of bananas. And many kinds of banana seeds are so big and hard that they are not suitable for human consumption at all. Now often eaten banana is a hybrid variety, after thousands of years of breeding and artificial breeding, banana seeds gradually degenerated, until disappeared.

Why do bananas have no seeds?

The bananas we eat now are improved after long-term artificial selection and cultivation. It turned out that wild bananas also had a very hard seed, which was very inconvenient to eat. later, under artificial cultivation and selection, wild bananas gradually developed in the direction that people wanted. over time, they changed the origin of hard seeds and gradually formed triploids, while triploid plants did not have seeds.

The reason why there are no seeds in bananas is that the bananas we eat have been transformed by human varieties and are unable to produce mature seeds that can breed. The little black spots we see are the seeds of developmental failure. Because wild bananas are multi-seeded and multi-fiber, people have cultivated a triploid banana, Xiangya banana, which is the banana we eat in our daily life.

Banana has no seed because it is cultivated by artificially induced polyploidy. This method includes the use of colchicine to increase the number of chromosomes in dividing cells. Eat triploid bananas produced by a cross between diploid and tetraploid bananas. In triploid plants, the synapsis of chromosomes is disordered during meiosis, unable to form normal germ cells, so bananas have no seeds.

In addition, even if some varieties of bananas still have seeds, the seeds are relatively small and underdeveloped. It is precisely because of this genetic and artificial intervention that today's common bananas usually have no seeds. This not only facilitates food and processing, but also meets the needs of large-scale commercial planting. Finally, it is worth mentioning that although bananas have no seeds or seed degradation, their reproduction methods can still ensure the sustainable development of the banana industry.

The reproduction of banana mainly depends on artificial cultivation techniques, including the use of seed germination or direct division from its parent plant to cultivate new banana plants. Although some wild bananas still have large seeds, the bananas we buy on the market have usually been improved and selected for a long time, and the seeds have become very small or even completely disappeared. Therefore, bananas do not have seeds because they have been improved and cultivated for a long time.

Do bananas have seeds?

In the early days, bananas had seeds, but in the later stage, bananas can be divided into seeded and seedless bananas. There is a kind of banana that we eat every day, this kind of banana may taste a little wrong. Seedless banana tastes better, but its price is also relatively higher. Seedless banana is the result of continuous cross breeding by botanists.

The propagation methods of banana mainly include sucking bud planting, tuber planting and ramet planting. It is generally believed that bananas have no seeds, in fact, because after a long period of artificial cultivation, the seeds have been degraded and lost the ability to reproduce naturally. Banana, which belongs to the genus Banana of Banana family, is an annual herb.

But the banana is a triploid plant that cannot reproduce on its own, so it has no seeds. In the wild, bananas multiply by sucking buds, tubers or ramets. In artificial cultivation, people replicate banana genes by asexual propagation techniques such as plant tissue culture, in order to maintain the stability and consistency of its characters. This way also leaves no seeds in the banana fruit. Therefore, we can't see seeds in bananas.

Strictly speaking, the bananas we usually eat are not without seeds. When we eat bananas, rows of brown dots can be seen in the pulp. These are the seeds. It's just that it hasn't been fully developed and degenerated into this way.

How can bananas reproduce without seeds

Seedless banana can be planted by sucking buds, tubers, plantlets and tissue culture, and the survival rate is high and the cultivation speed is fast. Sucking bud propagation is a common method of raising seedlings in banana cultivation. It is mainly propagated with sword sprouts (red bamboo shoots) and garments. The plantlets and buds used as seedlings are generally more than 40 cm high. Tuber propagation is mainly used to cultivate a large number of buds in a short period of time.

Sucking bud propagation: this is one of the most common propagation methods of bananas. In the right season, that is, November, bananas send out sword buds, which can be excavated and planted during the period from March to May. Another type of sucking bud, called buds, usually appears in August-October and can be planted in February-March of the following year. Tuber propagation: this method can produce banana buds more quickly.

Although bananas have no seeds, bananas can often be eaten because our banana planting method belongs to asexual reproduction, which does not need seeds.

Bananas are propagated mainly by tissue parts, and bananas are propagated by bud suction, tuber planting, ramification and other methods; this is true. Scientists have previously said that bananas may be on the verge of extinction in 30 years' time.

Some friends may ask, since bananas do not have seeds, when we plant bananas, we actually directly use the tissue part of the plant to reproduce. It has to be said that bananas are not without seeds, but the seeds have been gradually abandoned after generations of reproduction and cultivation. The main reason for this is that banana seeds have been degraded.
