Method and apparatus for estimating the water stress of a plant

Abstract

A method is described for estimating the water stress of a plant, wherein the inclination of a leaf, or a set of leaves, of the plant is detected at successive time instants wherein there are different stable illumination conditions on the leaf, and the occurrence of water stress is established or judged when the time course of the observed leaf/leaves inclination(s) corresponds to—or correlates with—a reference time course.
