The effect of white, blue, yellow, red and far‐red light on the quantitative synthesis of the primary and auxilliary photosynthetic pigments in cultured leaf primordia of Osmunda cinnamomea L. is reported. The P 660 form of the now classical photoreceptor pigment system, phytochrome, has been demonstrated to be active in chlorophyll synthesis in cultured cinnamon fern leaf primordia as shown by red/far‐red reversibility of chlorophyll synthesis. Also, it is apparent from the data presented that a blue absorbing pigment (P 420 ) is responsible for the extensive accumulation of chlorophylls and carotenoids in these cultured leaves.
