How does natural vegetation propagation occur?
Answers
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.
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.
