Permanent Wilting Point Definition
Permanent Wilting Point Definition. The wilting point, also called the permanent wilting point, may be defined as the amount of water per unit weight or per unit soil bulk volume in the soil, expressed in percent, that is held so tightly by the soil matrix that roots cannot absorb this water and a plant will wilt. Permanent wilting point is the minimum soil moisture required by a plant not to wilt, specifically at the root level.
Most greenhouse growers use a combination of. The definition of a permanent wilting point is what? Permanent wilting percentage (permanent wilting point, wilting coefficient, wilting point) the percentage of water remaining in the soil after a specified test plant has wilted under defined conditions, so that it will not recover unless it is given water.
