Question

Which of the following is cultivated through vegetative propagation?
A. Banana and Ginger
B. Potato and Sugarcane
C. Dahlia and Rose
D. All of the above

Answer 1

Hint:
Some plants can be produced vegetatively if they have some vegetative units such as buds or tubers. Some plants can also be artificially propagated if they are having some issues with seed production or their viability.

Complete answer:
Vegetative propagation is the formation of new plants from vegetative units such as buds, tubers, and rhizomes.
Banana plants are mainly propagated vegetatively by stem. The underground stem (rhizome), has multiple buds which sprout and form a pseudostem. These pseudostems are called suckers. Banana primarily propagates through suckers or rhizomes.
Ginger also propagates vegetatively. It is a modified, underground stem. The propagation of ginger is done by its stem, rhizome. Stems of ginger have small buds that will produce shoots; hence, vegetative propagation is observed.
Potato is a common example of vegetative propagation. Potato tubers have nodes from which the new growth is observed. The new stems growing are called sprouts which give rise to the new potato plant.
Sugarcane can be reproduced vegetatively. To grow them vegetatively, cut the plant in such that it will have at least one node. This node will give rise to primary roots and it can be propagated.
Dahlia can be vegetatively propagated using roots as well as stem parts. Propagation through root is the most common in Dahlia.
Rose is a common plant used in artificial vegetative propagation. They are artificially propagated because they don't produce viable seeds.
Hence all of the options given can be vegetatively propagated.

Option ‘D’ is correct

Note:
There are 2 methods of vegetative propagation: - Natural and artificial. In the natural method, plants are propagated through roots, stems, or leaves. In the artificial method, plants are cut at a particular position in roots, stems, or leaves and then put in the soil. Grafting is a common method used in artificial propagation.
