Question

Explain the different ways with examples in which plants can be reproduced vegetatively by artificial means.

Answer 1

Vegetative reproduction in plants can be carried out by artificial methods also. They are:
(a) Cutting: The vegetative parts of a plant, such as root, stem and leaves are cut off and placed in moist soil. These parts, later on develops roots and grows into a new plant. Sugarcane and Hibiscus are generally reproduced by this method.
(b) Grafting: In this method, the scion of one plant is placed on the stock of the other and is tied together. The stock which has roots, supplies water and minerals to the scion. After sometime, new cells starts developing at the region of joining, giving rise to a new type of plant. Example: Mango and rose plant.
(c) Layering: Layering is a method where a young branch from the plant is bent towards the ground and covered with moist soil. Once the branch develops roots, it is detached from the parent plant, allowing it to grow into a new plant. Grapes and jasmine reproduce by layering.
