tuber
tuber A swollen underground stem or root in certain plants. It enables the plant to survive the winter or dry season and is also a means of propagation. A stem tuber, such as the potato, forms at the end of an underground stem. Each tuber represents several nodes and internodes. The following season several new plants develop from the terminal and axillary buds (eyes). Root tubers, such as those of the dahlia, are modified food-storing adventitious roots and may also give rise to new plants.

tuber
tuber enlarged tip of a rhizome (underground stem) that stores food. Although much modified in structure, the tuber contains all the usual stem parts—bark, wood, pith, nodes, and internodes. The eyes of a potato tuber are nodes where sprouts appear, and they are arranged in the same spiral pattern characteristic of buds on an aerial stem. |

tuber
tuber A swollen stem or root that functions as an underground storage organ. Stem tubers (in potatoes, for example) often produce buds along the stem from which aerial stems arise the following season. Root tubers produce no buds, or produce buds only at the point where the tuber is attached to the stem of the plant.

tuber
tuber In plants, the short, swollen, sometimes edible underground stem, modified for the storage of food, as in the potato, or as a swollen root (for example, dahlia).
