Abstract

Seeds (achenes) of fringed sage were collected in central Saskatchewan in 1987, 1990, and 1991, and studies were conducted to determine the effects of imbibition time before brief or prolonged exposure to red (R) and far-red (FR) light on germination. A majority of the seeds required light for germination, but a substantial proportion germinated in darkness. Phytochrome controlled germination, and its activity was influenced by the duration of imbibition and by seed collections. At least 8 h of imbibition were required before phytochrome was activated by R light. The stimulation of germination could be reversed by FR light, and this suppression subsequently could be reversed by exposure to R light. Variable light requirements for germination of fringed sage can be met following large- or small-scale disturbances or in relatively undisturbed conditions.
