Effects of Colored Light on Seed Germination

Barnes, H. W. International Plant Propagators' Society, combined proceedings 2007, 57:364-370. 2008.

A survey of the literature shows that most phytochrome studies have been with either darkness, red light, or white light (Chory, 1996). Kavalen and Appelgren’s work (Kvaalen and Appelgren, 1999) is a notable exception with a study on the germination of somatic embryos and seeds in Picea abies with colored lights. The work here is to explore the possible effects of colored lights on the germination of Impatiens walleriana Accent Series, white, (Germania Seed Co. Chicago, Illinois) a light germinator; Delphinium Magic Fountains Series, pure white (Ferry Morris, Fulton, Kentucky) a dark germinator; Eragrostis trichodes, (Bammert Seed, Muleshoe, Texas) a light germinator; and Cortaderia selloana, (Germania Seed Company, Chicago, Illinois), a light germinator.
