Question

How does natural vegetation propagation occur?

Answer 1

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.

Answer 2

Natural vegetative propagation occurs from modified stems, roots, leaves and bulbs. Modified short stems of onion bear bulbs which when grown in soil develop into a new plant. Runners stems of doob grass have nodes and internodes. From nodes, roots are developed that form a new plant. Rhizome of ginger is a horizontal underground stem. If kept in soil with adequate moisture, it develops into a new plant. Tuber of potato bears eyes (buds), which when sown (entire or in pieces) in soil develops into a new plant.

Modified root tubers of sweet potato also grows into a new plant.

Buds produced in the notches along the leaf margin of Bryophyllum fall on the soil and develop into new plants.
