Abstract
Method and apparatus for measuring the effect of an external factor on a crop plant, comprising the steps of bringing at least one kind of molecules situated on the donor side of the electron transport system of the crop plant into an oxidized state; and measuring the absorption by the oxidized molecules at a wavelength determined by the oxidized molecules; characterized in that the operation of bringing into the oxidized state takes place after a first period after the external factor arises; and the method further comprises the steps of deducing at least one redox kinetics parameter of the molecules from the absorption measurement; and comparing the redox kinetics parameter with a comparison value.
