This vegetative part which has the ability to produce new plants is called vegetative propagule. Some common vegetative propagules are runner, rhizome, sucker, tuber, offset, bulb etc .
What are vegetative propagules give an example?
Vegetative propagules are the units of vegetative reproduction. These are the vegetative parts of the plants which give rise to new plants when they come into contact with damp soil or water. Examples: i Eyes in potato . ii Rhizome of banana and ginger.
Are vegetative propagules?
Vegetative propagules can be rhizomes, stolons, tubers, turions, simple stem or leaf fragments or even entire plants . Those are often formed by accident (e.g. herbivory, disturbances or management activities such as mowing or dredging), but they can also form spontaneously (Barrat-Segretain, 1996; Xie et al., 2010).

What are vegetative propagules give 4 examples?
examples are – tuber, runner, rhizome , offset . Vegetative Propagule means a part of the plant becomes detached from the rest of the plant and grows into a new one. Example: seed, spore, bud or a plant cutting.
What is vegetative propagule in banana?
Banana: Rhizomes are the vegetative propagules of banana plants. These are underground stems and produce adventitious roots and lateral shoots.
What is the vegetative propagules of ginger?
(b) Ginger: In ginger, vegetative propagation occurs through stems such as rhizome , where rhizome are the stems which grow horizontally under the ground, and this underground stem of ginger is swollen with food reserves, in this terminal bud grows upward to produce the new shoot, while lateral buds grow and separate to ...

What are the benefits of vegetative propagation?
- Quicker and more certain.
- Produces identical quality as the parent.
- Plants that do not have viable seed, can be reproduced.
- Flowers produced are of superior quality.
- Desirable character of fruit can be maintained.
What are vegetative propagules give examples Class 12?
Some common vegetative propagules are runner, rhizome, sucker, tuber, offset, bulb etc . Vegetative propagation is of two types i.e. natural vegetative propagation and artificial vegetative propagation. In natural vegetative propagation, a vegetative structure detaches from the parent plant and give rise to new plants.
What are the 5 types of vegetative propagation?
The most common forms of vegetative propagation are grafting, cutting, layering, tuber, bulb or stolon formation, suckering and tissue culture .
What are vegetative propagules give two examples Class 12?
In plants, the units of vegetative propagation such as runner, rhizome, sucker, tuber, offset, bulb are all capable of giving rise to new offsprings. Such structures are called vegetative propagules.
Is banana a vegetative reproduction?
Commercial bananas are seedless and propagated exclusively by vegetative means . The banana has a reduced underground stem, called the rhizome, which bears several buds. Each of these buds sprouts and forms its own pseudostem and a new bulbous rhizome. These daughter plants are called suckers.
What are the vegetative propagules in potato?
Potatoes are mainly propagated by vegetative methods (cloning). Potato tubers have nodes or eyes from which the new growth begins. The new stems growing from each eye are called sprouts which giver rise to the new plant. Vegetative seed can be either a whole tuber or a cut tuber .
