The wavelength dependence for a radiation induced increase of phytochrome in mung bean hooks ( Vigna radiata L.), preirradiated with red light, was determined between 640 to 800 nm. Radiation between 640 to 700 nm and 780 to 800 nm had little effect on phytochrome concentration in hooks pretreated with red. Two bands of far‐red light, one at 710 nm and the other at 750 to 760 nm, were found to increase phytochrome content about four times. Besides the requirement for a photochemical process, one or more dark processes appear to be necessary for the induction of phytochrome increase.
