Question

Name any two artificial methods of vegetative propagation from stem? ​

Answer 1

Answer:

Vegetative propagation is an asexual method of plant reproduction that occurs in its leaves, roots and stem.

Artificial method of vegetative propagation:

Cutting – In this, a portion of a plant is cut and planted in the soil, usually a stem or a leaf. These cuttings are sometimes treated with hormones in order to induce root growth. The new plant originates from the adventitious roots that grow from the cutting process.

Grafting – In this, the cutting from some other plant is added to the plant stem embedded in the soil. The graft tissues become incorporated with the rooted plant tissues and grow over time as a single plant.

Layering – In this, the stem of the plant is bent to the ground and covered with soil. Adventitious roots emerge from the plant parts covered with the soil. This attached stem with developing roots is known as a layer.
