Detailed explanation-1: -Natural vegetative propagation occurs by means of roots, underground stems, subaerial stems, aerial shoots, leaves and bulbils. Artificial vegetative propagation occurs by use of special vegetative parts such as root tubers, corm, parts of rhizome etc., or by cutting, layering, grafting and bud grafting.

Detailed explanation-2: -Tissue culture, Cutting, Layering, and Grafting are types of Artificial methods of vegetative propagation.

Detailed explanation-3: -Vegetative propagation methods include: • rooting of cuttings, • layering or marcotting, • grafting, • micropropagation.

Detailed explanation-4: -Natural vegetative propagation occurs when an axillary bud grows into a lateral shoot and develops its own roots (also known as adventitious roots). Plant structures allowing natural vegetative propagation include bulbs, rhizomes, stolons and tubers.
