Question

Which of the following is used for the propagation of Ginger.
(a) Seed
(b) Stem (rhizome)
(c) Root
(d) Leaf

Answer 1

Hint: They are a modified subterranean plant stem that sends out roots and shoots from its nodes. They’re also called creeping rootstocks or simply rootstocks. They develop from axillary buds and grow horizontally.

Complete answer:
Propagation is defined because of the production of the whole plant from the vegetative parts like the leaf, stem, and roots of the parent plant. In ginger, vegetative propagation takes place through the underground stem known as the rhizome. A rhizome is an underground horizontal stem with reserve foods and buds. Terminal and lateral buds produce new shoots. The new shoots develop green leaves and photosynthesis. Manufactured foods are transported right down to enable the expansion of the rhizome. The lower portion of the rhizome develops roots and helps within the conduction of water and minerals.

Additional information:
Ginger is a herbaceous perennial that develops annual pseudostems (false stems made from the rolled bottom of leaves) around 1 meter long having narrow leaf blades. The inflorescences bear flowers possessing straw petals with purple edges and develop directly from the rhizome on separate shoots. Rhizomes are non-green with distinct nodes and internodes. They are auxiliary also as apical buds. These are brownish in color. The common sorts of rhizomes are fleshy because of the storage of food material. It also contains terminal buds. E.g., ginger. The rhizome rootstock grows vertically upwards rather than horizontally. Banana and Alocasia indica are some samples of the rhizome.

So, the correct answer is ‘Stem (rhizome)’.

Note:
The scientific name of ginger is Zingiber officinale, which is an angiosperm having rhizome, ginger root or ginger is vastly utilized as a spice and folk medicine. Rhizomes also are known as root stalks, which basically develop perpendicular to the direction of the force of gravity that is they grow horizontally. The rhizome rootstock grows vertically upwards rather than horizontally. The common sorts of rhizomes are Alocasia indica, ginger, and banana.
