Vegetative propagation is an asexual method of plant reproduction. This happens in leaves, roots, and stem. Vegetative propagation is through runners, stolon, stem and root cuttings , tubers, dormant apices and offsets.
Vegetative Propagation by underground stem – Rhizome
Diagnostic Features
• Ginger is a underground stem which is called as Rhizome.
• Rhizomes are horizontal and swollen due to the storage of food materials.
• The terminal buds turn upwards to produce the aerial flowering shoot and the lateral buds grow out to form new rhizomes.
Vegetative Propagation by sub-aerial stem – Sucker
Diagnostic Features
• The suckers of Chrysanthemum are used for propagating plants.
• Suckers grows horizontally under the soil and then emerge out obliquely from the soil and give rise to a new plant or leafy shoot.
• The sucker has nodes and internodes. In the nodal region, it bears axillary buds above and adventitious roots below.
Vegetative Propagation by epiphyllous buds - Bryophyllum
Diagnostic Features
• In Bryophyllum, adventitious buds arise on the leaf margins. These are called epiphyllous buds.
• When the leaves fall off the epiphyllous buds develop roots into the
soil and becomes independent plants.
