Question

For commercial propagation of banana and ginger which of the following parts are utilised respectively?
A. Rhizome, Sucker
B. Rhizome, tuber
C. Tuber, bulb
D. Sucker, Rhizome

Answer 1

Asexual reproduction occurs without the fusion of gametes. A new plant can be grown from the body part of a plant. Vegetative propagation can be done by leaf, stem, root, tubers, etc.

Complete Answer:
Many plant parts like root, leaves and stem, under the right conditions, can grow into new plants. This mode of reproduction is known as vegetative propagation. This vegetative propagation property is used for agricultural purposes, or for grafting or layering to grow several plants, such as rose, sugarcane, or grapes. The plants produced by vegetative propagation tend to bear flowers and fruits earlier than those produced from seed.

Commercial bananas are seedless and produced solely by vegetative means. The banana contains a reduced underground stem called a rhizome that bears many buds. These buds can sprout and produce a stem and a fresh bulbous rhizome. The new plants are known as suckers. Banana is mostly propagated by rhizomes and suckers. Ginger is vegetatively propagated from tiny pieces of the rhizome called sets. Sets are obtained by cutting a small piece of living rhizome. Each piece has at least one live bud that will grow shoots.

Thus, the correct answer is option D. Sucker, Rhizome.

Note: In plants, the vegetative propagation units including runner, sucker, tuber, rhizome, offset, and bulb have the ability to produce new offspring. These structures are termed vegetation propagules. The mechanism involved is asexual, because the development of these structures does not include two parents.
