How do bananas reproduce?

Banana is a kind of nutritious sweet fruit, ripe banana tastes soft and waxy and delicious, so how does banana reproduce?

There are many propagation methods of banana, which are bud absorption, plant division, tissue culture, tuber propagation and so on, among which bud absorption propagation is the most commonly used propagation method in banana cultivation.

First, sucking buds

Absorbing buds are mainly propagated by sword buds (red bamboo shoots) and red bamboo shoots. Red bamboo shoots generally grow in November of the previous year and are used when planting in March, April and May of the same year.

Jacket buds generally grow in August, September and October of the previous year, and are usually used when planting in February and March.

2. Ramets

Sucking buds are also needed for ramet propagation. When the sucking buds grow to more than 40 centimeters, they can be divided and reserved for the next generation of mother plants or as seedlings. When dividing a plant, the soil next to the sucking bud should be dug up first, and then cut with a shovel between the mother plant and the sucking bud. After the seedlings are dug out, cut off the excessively long and injured roots, dry the incisions in the shade or smear them with plant ash before they can be planted.

III. Tissue culture

The main results are as follows: 1. In the banana planting area without traditional diseases, the mother plants with strong growth, neat fruit hanging and high yield were selected, and the sucking buds just exposed to the ground were dug as induction materials.

2. When disinfecting, peel off the leaf sheath outside the suction bud, rinse it with water and disinfect it with 75% alcohol solution under aseptic condition for 30 seconds.

3. Disinfect it with 0.1% HgCl for 20 minutes, then rinse it with sterile water for 8 times, cut the stem tip, divide it into two parts, put it in the induction medium of MS+3~6 mg / L BA+ sugar 3% + Agar 7.0g / L, put it in the dark light incubator, keep the temperature 28: 30 ℃, and culture 40: 50 days.

IV. Tuber propagation

Using plants that have not yet blossomed or underground stems with large sucking buds (sprouting from October to November) as materials, the best time to cut into pieces is from November to January of the following year, most of them can germinate, and the seedlings in April, May and June can be planted with a height of 40cm to 50cm.
