Vegetative Propagation

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.

Advantages of vegetative propagation 
1. The process is cheap and beneficial to farmers 
2. Flower or fruits produced are superior in quality 
3. Farmers get quick output
 4. The characters of parent plant remains unchanged 
5. Many plants can be reproduced in short time 
6. The plants which don’t produce viable seeds can be reproduced by this method
