Artificial Vegetative Reproduction

Plants can also be propagated by some artificial methods.Growing plants through
artificial methods is known as artificial propagation.

This is a type of vegetative reproduction carried out by humans on the fields and
laboratories.

The most common types of vegetative reproduction occurring artificially include:

1. Cutting

 In this, a part of a plant, specifically a piece of shoot, root or leaf is cut and
planted in the soil.

 In plants such as rose, sugarcane and Bougainvillea that have nodes and
internodes, their stem is obliquely cut and planted in the soil.

 The stem then grows into a new plant.

2. Grafting

 In this method, the two parts of the plant are joined to grow together. These
parts can be of the same type of plants or different types of plants.
