How Do Bananas Reproduce? A Detailed Explanation of Banana Propagation Methods

Bananas are a nutrient-rich sweet fruit, and ripe bananas taste soft, sticky and delicious, so how do bananas reproduce?

There are several propagation methods for bananas, namely suckers, division, tissue culture, and corm propagation. Among them, sucker propagation is the most commonly used propagation method in banana cultivation, and sucker propagation mainly uses sword suckers (red shoots) and water suckers for propagation.

I. Suckers

Sucker propagation mainly uses sword suckers (red shoots) and water suckers. Red shoots generally grow in November of the previous year and are used for planting in March, April and May of the current year.

Water sucker shoots generally grow in August, September and October of the previous year and are generally used for planting in February and March.

II. Division

Division propagation also requires the use of suckers. When the suckers grow to more than 40 cm, they can be divided and kept as the mother plant for the next generation or used as seedlings. When dividing, first dig open the soil beside the sucker, then use a shovel to cut between the mother plant and the sucker. After the seedling is dug out, cut off excessively long and damaged roots, dry the cut surface in the shade or smear it with plant ash, and then it can be planted.

III. Tissue Culture

1. In banana planting areas free of traditional diseases, select mother plants with strong growth, uniform fruiting and high yield, and dig up suckers that have just emerged from the ground as induction materials.

2. During disinfection, first peel off the leaf sheaths outside the suckers, rinse them clean with water, and then disinfect them under aseptic conditions with a 75% alcohol solution for 30 seconds.

3. Then disinfect with HgCl at a concentration of 0.1% for 20 minutes, then rinse with sterile water 7 to 8 times, cut off the shoot tips, divide the shoot tips into 2 parts, place them in an induction medium of MS + 3 to 6 mg/L BA + 3% sugar + 7.0 g/L agar, and place them in a dark light incubator, maintaining a temperature of 28 to 30°C. After culturing for 40 to 50 days, they will sprout.

IV. Corm Propagation

Use the underground stems of plants that have not yet flowered or fruited, or large suckers (sprouting in October to November), as materials. The best time for cutting into pieces is from November to January of the following year. Most of them can sprout, and when the seedlings are 40 to 50 cm tall in April, May and June, they can be planted.
