* Vegetative reproduction is the production of new plant using any part of a plant except the seeds.
* Vegetative reproduction is a form of asexual reproduction since no gametes are used.
* 8 types of vegetative reproduction :
* Runners / stolons
* Stem tubers
* RUNNERS / STOLONS
Runners are stems which grow horizontally over the surface of the ground. Shoots and roots of the young plant grow from the nodes of the runners. Example : strawberry plant, sweet potato, grass, Indian pennywort (pegaga).
A rhizomes is a horizontal underground storage stem which scale leaves and buds. The buds grow into shoots above the ground and produce new daughter plants. Example : ginger, lallang, turmeric, asparagus, lemon grass (serai).
A corm is a thick, short and swollen underground stem that grow upright containing food reserves. Under suitable conditions, the buds use the food reserves and grow into new aerial shoots producing leaves and flowers. Example : water chestnut, yam.
A bulb is a modified stem made up of flattened disc-like stem and leaves swollen with food. Young buds can develop into new plants.
Example : onion, garlic, shallot.
Plants which reproduce by leaves have thick and fleshy leaves. New plants grow at the sides of mature leaves.
Example : Bryophyllum , begonia , aloe vera.
A sucker is a new shoot which grows from the underground part of the stem. The sucker grows upwards and becomes a new plant.
Example : banana plant, bamboo, pineapple plant.
