FROM A PHYSIOLOGICAL PERSPECTIVE, a plant's response to stress, for example, temperature extremes or drought, can be characterized as either avoidance (the factor is excluded from the plant tissue) or tolerance (the factor penetrates the tissue but the tissue survives) (Levitt, 1964). Kochian (1995) extended this mechanistic terminology to stress from Al using the terms exclusion, rather than avoidance, and tolerance. Physiologically, the term resistance is mechanism neutral; that is, it implies neither tolerance nor exclusion. In this paper, we will use the term resistance to characterize the response of white clover to Al and acid-soil stress.
