Hy*drot"ro*pism, n. (Bot.)

In a broader sense, any curvature or turning induced in certain growing plant organs under the influence of moisture.

⇒ When the movement is toward the moisture, as is the case in most roots, the phenomenon is called positive hydrotropism; when away from the moisture, as in the case of hyphae of certain fungi, negative hydrotropism.
