​

Answer 1

Answer:

Explain artificial methods of vegetative propagation in plants.

Answer:

Cutting – In this, a portion of a plant is cut and planted in the soil, usually a stem or a leaf. ...

Grafting – In this, the cutting from some other plant is added to the plant stem embedded in the soil. ...

Layering – In this, the stem of the plant is bent to the ground and covered with soil.

Answer 2

Answer:-

Artificial vegetative propagation is carried out by stem-cutting , layering grafting and tissue culture.

Stem-cutting

The cutting develops roots and grows into a new plant. Cutting of a healthy young branch of a plant having leaf birds is planted in the moist soil.

Examples:- Rose , sugarcane, and many more.

Layering

A young brands is bent to touch the ground as it is covered with moist soil it forms a layer. when the root develops from the covered part the branch is cut off from the parent plant then it grows into a new plant.

Examples:- Jasmine, Mint.

Grafting

It is a technique of combining the characteristics of to plants. many new varieties of of clans developed by this method.

Examples:- Guava, Lemon.

Tissue culture ( Micropropagation )

Tissue culture is also called micropropagation. It is the process of growing new plants by cell culture or tissue culture technique.

Examples:- Asparagus, Orchids.

More Info:-

• In tissue culture technique of small piece of tissue is cut of from the growing tip of a plant then it's cell divides rapidly and former cell mass called callus. Then the cells of callus in the nutrient medium and differentiate into roots and shoots and form plantlets.
• There are two types of vegetative propagation ( in plants )

1. Natural method of vegetative propagation.
2. Artificial vegetative propagation.

• Some advantages of vegetative propagation:-

1. Rapid multiplication
2. Easy to grow
3. Genetically identical
4. Multiplication without seed formation.
