In ginger, vegetative propagation occurs through:

Rhizome: It is a thick stem growing horizontally, beneath the soil surface. It has distinct nodes and internodes. The nodes bear small scale leaves with buds in their axils. These buds develop into aerial shoot during favourable conditions. The tip of the rhizome ends in a terminal bud. The lower surfaces of the nodes give out small slender adventitious roots. E.g. ginger, turmeric, etc.
