How are bananas reproduced? How are bananas reproduced?

Asexual reproduction. Now it is mainly tissue culture.

You can't see the seeds of the banana you usually eat, so how does it reproduce?

There are two main ways of reproduction of bananas: sexual reproduction and asexual reproduction.

Sexual reproduction refers to the pollination of pollen, which causes the pollen to combine with the pistil to form seeds, which in turn reproduce new banana plants. The pollen of bananas is spread by wind or insects and is pollinated by falling on the pistils of other bananas. Since the pollen of bananas is very small, it is difficult to reproduce sexually under natural conditions, so most bananas are grown through asexual propagation.

Asexual reproduction refers to the direct use of the mother plant of a banana for propagation. The mother plant of a banana propagates new roots and shoots through underground stems, which gradually grow and mature to become a new banana plant on its own. Bananas propagated in this way are basically the same as the mother plant, with the same genotypic and phenotypic characteristics.

The advantage of asexual reproduction is that it reproduces quickly and has a high reproductive success rate, but because all the produced bananas have the same genotype, it is easy to lead to the spread of pests and diseases and the reduction of disease resistance.

In general, bananas are mainly cultivated and produced through asexual reproduction, while sexual reproduction occurs occasionally in the natural environment, Lai said.

Cultivation techniques of bananas

Bananas are often cultivated as fruit trees, but as ornamental plants are cultivated only in home gardens. For example, when bananas are cultivated as fruit trees, large holes should be dug and manure or compost should be applied as base fertilizer in the holes. The planting depth should cover about 7 cm of the banana head.

After planting, you can cut off some of the leaves to keep the soil moist. Before the new roots occur in winter to early spring, it is necessary to carry out a ploughing and plough the ground for about 12 cm. In spring, you can properly shallow tillage to remove weeds, such as the root system is covered with topsoil, do not hoe, only pull out weeds by hand.

Bananas require a large amount of fertilizer, and the method of applying nitrogen, phosphorus and potassium fertilizer should be used frequently. Fertilize 1 time in January-February. Heavy fertilizer is applied once before winter, mainly compost, plant ash, pond mud, fire soil, etc.

Frequent watering is required during the growing season, and irrigation should be carried out during drought. In spring and summer, high temperature and rain are easy to cause rotten roots, so we should pay attention to the drainage cover.

Tuber multiplication jujube and bright belt breeding: in order to cultivate a large number of sprouts in a short period of time and the propagation method is adopted, using plants that have not yet flowered and fruited or underground stems with large budding (germination in October and November) as the material, and the cutting time is best in November and January of the following year;

Most of them can germinate the seedlings 40 50 cm high can be planted, the advantage of this propagation method is that it can reduce pests and diseases, the survival rate is high, the growth, the fruit is neat, the initial plant is shorter than the sucking bud propagation bench reed, more resistant to wind, but there are the shortcomings of the first generation of low yield.

The method of underground stem cutting and propagation, first cut off the underground plant, dig up the tuber, leave the false stem 12 15 cm high, and then cut the tuber into small pieces, each piece weighs about 120 grams or more, and then according to the plant row spacing of 15 cm, the cut piece is placed flat on the furrow, the bud eye is facing up, and then the soil is covered with grass, and the fertilization management is carried out.
