Phalaris arundinacea is an invasive species in some regions of North America. The literature on how the light environment affects seed germination in Phalaris arundinacea is contradictory, and clarification is necessary for understanding its mechanisms of invasion. In our trials, germination was photoperiod insensitive in the range of 12 to 16 hours. Highest germination percentages (up to 80) were obtained under white light and red light (11.0 μmol s-1 m-2) and up to 40 with high red: far-red ratios. Virtually no germination occurred in the dark. Our results are not consistent with early reports that P. arundinacea germination occurred in the dark and was light insensitive, but they are consistent with a recent report that it does not germinate in the dark and our own field and greenhouse observations.
