Question

Which of the following is a mode of vegetative propagation in ginger?
A) Bulbils
B) Runners
C)Rhizome
D) Offsets

Answer 1

Vegetative propagation is defined as a type of asexual reproduction that happens in plant. A New plant grows from a fragment of a parent plant or any other specialized reproductive structure. In the ginger, the vegetative reproduction occurs through rhizome.

Complete answer:
The vegetative propagation is a process that involves structural modifications of the stem, leaf, or root that contribute to vegetative reproduction of the plant.
The most common modified stem, leaves, roots that allow vegetative propagation are:

BULBILS- Bulbil is modified vegetative or floral buds that stores food and helps in vegetative propagation. Agavoideae produces bulbils.
RUNNERS – Also known as stolons, they are modified stems grown from existing stems just below the soil surface. The buds on the modified stems produce roots and stems. The plants that use runners are- strawberries and currants.
RHIZOMES- They develop from the axillary buds. They grow horizontally.Rhizome has also the ability to allow new shoots to grow upwards. The rhizome is the main stem of the plant. The plant uses its rhizome to store starch, proteins and other nutrients.
Examples of plants that propagate through rhizome are:Asparagus, ginger, lily, cannas etc.
OFFSET-Small, virtually complete daughter plant. Offset forms when axillary buds differentiate into new plants.
Bulbs, Corms, Tubers, etc. are other ways of vegetative propagation

Note: Vegetative propagation is economically beneficial to clone a certain plant to ensure consistency throughout their crops.
