Vegetative propagation through modified stem:
- Plants which have modified stems are called tuberous stem.
- It has nodes which bear buds which can form new plants.
- Each of the buds are called the eyes (appears like scar) in a potato which can grow into a new plant when it is planted in the soil.
- The tubers (stem or root) can store nutrients or food.
Other plants like ginger and turmeric also have buds on the stem tuber.
Other methods that involve vegetative propagation through stem are grafting, budding, and layering.
Vegetative propagation through leaves:
Bryophyllum (also called sprout leaf plant) has buds in the leaf margin. If the leaf is burried on a moist soil, the margins of the leaves develop into a new plant that resemble parent.
Vegetative propagation through roots:
- In plants like sweet potato, dahlia, etc., a new plant develops through tuberous roots (acts as a storage organ) and bulbs (onion).
- There are buds present on these modified storage roots that can grow above the ground and a new plant is formed.
Advantages of Vegetative propagation
- It takes less time to grow and also bears flowers and fruits earlier than those produced from seeds.
- New plants are exactly the copies of the parent plant.
