Photosensitive site in lettuce seeds.

Hiroshi Ikuma; Kenneth V. Thimann

Red light is effective only in promoting germination of Grand Rapids lettuce seeds, and far-red light is effective only in inhibiting it, when the hypocotyl half of the seed is exposed to the light. It is concluded that the photoreceptor is probably located in the tip of the hypocotyl.
