In essence, asexual reproduction is to produce new offspring through mitosis of maternal cells, and the offspring generally do not undergo gene recombination, and their genetic composition is consistent with their parents.

Asexual reproduction is divided into natural asexual reproduction and artificial asexual reproduction, including cutting, layering, grafting and plant tissue culture;

Cutting cuts off vegetative organs such as roots, stems, leaves or scales from the parent plant and inserts them into the soil under appropriate conditions. Because of their branching ability and regeneration ability, the lost organs regenerate and develop into new plants. Lemons and azaleas often use this method.

Many of them are suitable for asexual reproduction, such as potatoes, strawberries and daffodils.

The layering is to bury the branches or stems and vines of the mother plant in the soil, and then cut them off from the mother plant after taking root. Litchi trees and longan often use this.

Not to mention plant tissue culture? There are many books.
