प्रश्न
Define vegetative propagation. List its two methods.
उत्तर
Vegetative propagation is a type of asexual reproduction where a new plant is produced from the roots, stem, leaves, and buds of flowers.
Vegetative propagation takes place by the following methods:
-
Through stems − Some plants such as rose propagate through stem cutting. The stem contains nodes on them. A node is the region of a plant from which leaves arise. The piece of stem bearing node is called cutting. When such cuttings are placed in a pot and watered as per requirement, they start giving out roots and leaves. Thus, a new plant can be obtained through stem cutting.
- Through buds − A vegetative bud consists of a short stem around which immature overlapping leaves are present in a folded state. A bud can give rise to a new plant.
