Seven days old dark‐grown etiolated seedlings of wheat cultivated on nutrition solution were given short light impulses of high intensity followed by a dark period, during which the phytolization of chlorophyllic α was studied. If the leaves prior to the short light impulses were given a pretreatment consisting of a light impulse followed by three hours of darkness the phytolization rate increased. Monochromatic light as pretreatment gave a response which was mainly restricted to the red region with a peak around 660 nm.
