Vegetative Propagation
Vegetative propagation is growing a new plant from a vegetative part (root, stem, leaf) without seeds — potato propagates through its eye buds.
Why this matters
1 PYQ, EASY. Vegetative propagation is asexual reproduction in plants from a non-seed part. The one tested example: potato grows new plants from its 'eyes' (axillary buds on the tuber).
Concept 1 of 1: Vegetative propagation — the organs that do it
Definition
Vegetative propagation is asexual reproduction in plants from a vegetative part (root, stem or leaf) — no seeds, no fertilisation, so the offspring is genetically identical to the parent. Common examples:
- Potato — propagates through eye buds (axillary buds in the depressions of the stem tuber).
- Ginger — through its rhizome (underground stem).
- Onion — through its bulb.
- Sugarcane — through stem cuttings (nodes).
| Plant | Propagating part |
|---|---|
| Potato | Eye buds (on the tuber) Vegetative propagation through eye buds = potato (NDA 2024). |
| Ginger | Rhizome (underground stem) |
| Onion | Bulb |
| Sugarcane | Stem cuttings (nodes) |
