Vegetative
propagation is an asexual method of plant reproduction that
occurs in its leaves, roots and stem. This can occur through fragmentation and
regeneration of specific vegetative parts of plants.
· Vegetative propagation from root: Some plant roots have capacity to reproduce new plants from root. The buds present on the roots grow as leafy shoots called slips above ground and adventitious roots at their bases. Each slip gives rise to a new plant. eg. Sweet potato, Topioca, yam, Dahlia and Tinospora.
· Vegetative propagation from stem: In plant kingdom there are many types of stem and many types of propagation of new plants from stem. Types of stem are
1. Underground stem: they are further subdivided to rhizome, tuber, bulb and corm
From Rhizome: Ginger
From Tuber: Potato
From Bulb: Onion and Garlic
From Corm: Colocasia, Amorphophalus
2. Subaerial stem:
From stolon: Strawberry
From Offset: Cactus
3. Aerial stem: Rose, sugarcan, lemon, orange, mango etc
· Vegetative propagation from leaves: Vegetative propagation from leaf is rare case but commonly seen on bryophyllum.
