Vegetative propagation is a kind of propagation method to produce new plants from roots, stems, leaves and other organs of plants or some special tissues. This kind of reproduction does not involve the fusion of sexual cells, so it belongs to the category of asexual reproduction.

Function:

1。 In essence, vegetative propagation produces new offspring through mitosis of maternal cells, and the offspring generally do not undergo gene recombination, so the genetic composition is consistent with that of the parents, so the excellent characters of the parents can be maintained.

2。 Under natural conditions, the vegetative organs of some plants have certain regeneration ability, stems or branches can grow adventitious roots, and adventitious buds can be produced on the roots, thus growing into new plants.

For example, the stolon of strawberry, the bulb of onion and lily, the tuber of potato with bud eyes, the rhizome of bamboo, the tuberous root of sweet potato, the fleshy leaves rooted on the ground and so on. , can be asexual reproduction.

3。 Artificial asexual reproduction can be achieved by artificially removing some vegetative organs or tissues of plants and culturing them into new plants in vitro, which is more purposeful, commercialized and efficient.
