How Do Bananas Reproduce? An Introduction to Common Propagation Methods
As we all know, most plants reproduce through seeds, and some special plants reproduce through other means. The banana, a fruit familiar to us in China, has no seeds, so it cannot be propagated by sowing. So how do bananas reproduce? Let's take a look at the detailed introduction below.
1. Sucker propagation
Sucker propagation is a relatively traditional method of banana cultivation. It mainly uses banana sword suckers and corm suckers for propagation. Sword suckers generally emerge in November of the previous year and break through the ground after the weather warms up following the Start of Spring; they are red in color and are usually dug out and planted in spring from March to May. Corm suckers generally emerge in autumn from August to October and temporarily wither during dry, low-temperature periods; they are usually dug out and planted in spring from February to March.
2. Corm propagation
Corm propagation is generally used in production to cultivate large numbers of shoots and seedlings. Using the underground stem of a plant that has not yet flowered or of a large sucker as the material, it is cut into evenly sized small pieces, each required to carry 1-2 buds. After cutting, the wounds are coated with plant ash and left in a shady place to dry, then placed flat on the seedbed surface at a row spacing of 15 cm with the buds facing up, covered with soil and grass. They are generally planted in November-December and sprout the following spring in January-February; by May-June, when they have grown to 40-50 cm, they can be dug out and planted in the field.
3. Division propagation
Division propagation also uses suckers for propagation. When a sucker has grown to more than 40 cm, it can be divided off and kept as the mother plant or planting stock for the next generation. Division involves digging away the soil beside the sucker and using a tool to separate it from the mother plant; after digging it out, the overly long and damaged roots are trimmed off, the wounds are coated with plant ash, and it is placed in a shady spot to dry, after which it can be planted.
4. Tissue culture
This is generally used to cultivate disease-free seedlings and to raise seedlings in large quantities, and it is currently widely applied in production. It uses rapid tissue-culture propagation technology, which can not only produce a large number of seedlings in a short time, but also eliminate diseases such as mosaic virus, with a clear effect on increasing yield.
