Abstract:
:Phototransformation of phytochrome in lettuce seeds (Lactuca sativa L. var. Grand Rapids) was examined by testing germination responses of seeds irradiated at various temperatures. Temperature variations from 0 to 50 C had no influence on the germination of partially hydrated seeds (about 15% water content) irradiated with either red or far red light prior to imbibition. At -15 C far red light more effectively retarded germination than red light promoted it. No effective phototransformation was detected at -79 C or -196 C.
