Swollen region of an underground stem or
root, usually modified for storing food. The
potato is a stem tuber, as shown by the
presence of terminal and lateral buds, the
`eyes' of the potato. Root tubers, developed
from adventitious roots, lack these. Both
types of tuber can give rise to new
individuals and so provide a means of
vegetative reproduction. Unlike a bulb, a
tuber persists for one season only; new
tubers developing on a plant in the following
year are formed in different places. See also
rhizome.
