In ginger, vegetative propagation occurs through:

Explanation

The rhizome is a thickened, underground, dorsoventral stem that grows horizontally at a particular depth within the soil. It is brown in color and shows cymose branching. It can be distinguished from the modified root by the presence of nodes, internodes, terminal buds, axillary buds, and scale leaves. The rhizomes are perennial and propagate vegetatively. They store food materials and appear tuberous. E.g., Zingiber officinale (ginger), Curcuma longa (turmeric), Canna indica.A bulbil is a small, young plant that is reproduced vegetatively from axillary buds on the parent plant's stem or in place of a flower on an inflorescence. These young plants are clones of the parent plant that produced them-they have identical genetic material.A runner is a slender stem that grows horizontally along the ground, giving rise to roots and aerial (vertical) branches at specialized points called nodes.An offset (also called a pup) is a small, virtually complete daughter plant that has been naturally and asexually produced on the mother plant.
