Why do bananas have no seeds and what is the way they reproduce?

Many people must have a question in their hearts: "Why do bananas have no seeds? what is the way they reproduce?" In fact, the original original banana has seeds, the original wild banana has a very hard seed, it is extremely inconvenient to eat. After long-term cultivation and selection, wild bananas have been mutated and there are no seeds in the fruit.

Today's bananas are triploid and do not produce seeds. There are 3 groups of chromosomes in banana cells, each with 11 chromosomes. The process in which cells form spermatocytes and eggs requires special cell division, that is, meiosis. It is obvious that 11 chromosomes in each group can not undergo normal meiosis. Without the formation of egg and sperm cells, seeds cannot be produced.

This situation is similar to the growth of seedless watermelons. So bananas can only be planted through asexual reproduction. There will be a small black spot in the banana. Many people think it is the seed of the banana. In fact, those are just the peel of the seed. Banana itself has seeds, but after years of artificial improvement, bananas can not seed normally, leaving the peel of the seed. Seeds can still be found in wild bananas.

The asexual propagation of banana is mainly cultivated into seedlings by adventitious buds in the bulb, and then planted to develop into banana plants.

The method of growing bananas:

Cut the bulb into small pieces according to the number and growth position of strong buds, and the buds are facing up and covered with soil. The seedlings can be transplanted when they grow to about half a meter. Asexual reproduction can retain the genetic characteristics of the mother, and the excellent characters of the mother can be continued.

As we all know, banana is a kind of tropical fruit tree, its growth temperature is relatively good, generally must reach more than 21 degrees; at the same time, banana is more sensitive to soil quality, weak acidic soil conditions may be more suitable for banana growth and development.

In the process of growth and development, bananas have a great demand for water and fertilizer, so we should pay attention to replenishing water and fertilizer in time, especially in high temperature weather, and bananas need a lot of fertilizer and potassium. Attention should be paid to the amount of potash fertilizer in the process of fertilization.

In the process of banana cultivation, we should pay attention to the wind, so as not to reduce the yield. Because the leaves are large and the rhizomes are fragile, the leaves may be blown down or broken by the wind during the growth process.
