Question

Vegetative propagation is not good because?

Answer 1

Hint: Plants use their leaves, roots, and stems for vegetative propagation, which is an asexual way of reproduction. Plant fragmentation and the regeneration of specific vegetative components can cause this.
Grafting and budding, among other methods of vegetative propagation, aid in the growth of new plants from the vegetative components of older plants.
Vegetative reproduction results in physically and genetically identical offspring.
In nonvascular plants, gemmae and spores are vegetative reproductive structures, but in vascular plants, stems, tribulations, leaves, and nodes are involved in transplantation.

Complete answer:
Because there is little genetic variety in vegetative propagation, it is less adaptable to the environment.
Advantages of vegetative propagation are-
Flowers and fruits can be generated early with this method because it is a rapid method.
This method of creating new plants is more reliable than seed reproduction.
It is more cost-effective for the plant because no energy is lost in the production of huge, showy petals, nectar, fruits, seeds, and so on.
Plants created through vegetative reproduction are identical to their parents. Thus, the best types of potatoes, oranges, apples, and other fruits and vegetables can be kept through vegetative reproduction without sacrificing their high quality. This allows for the selection and propagation of pure lines of chosen sorts all across the world.
Disadvantages of vegetative propagation are-
There is considerable rivalry amongst members of the same species due to the overcrowding of a high number of plants near the parent plants. As a result, many plants grow stunted and feeble.
Due to a lack of sexual stimulation, species may degenerate.
There may be no evolution of new species due to a lack of genetic variety in vegetative reproductive system.

Note:
Types of vegetative propagation-
Natural vegetative propagation: This happens when plants grow and develop spontaneously without the intervention of humans. The growth of adventitious roots can aid natural vegetative propagation. As a result, new plants may sprout from the roots, stem, and leaves of the parent plant.
Artificial vegetative propagation: Humans use this method of vegetative reproduction in the fields and laboratories. The following are the most common types of vegetative reproduction that occur artificially: cutting, grafting, layering, tissue culture
