Abstract
Phalaris arundinacea is an invasive species in someregions of North America. The literature on how the light environment affectsseed germination in Phalaris arundinacea is contradictory,and clarification is necessary for understanding its mechanisms of invasion. Inour trials, germination was photoperiod insensitive in the range of 12 to 16hours. Highest germination percentages (up to 80) were obtained under whitelight and red light (11.0 ) and up to 40 with high red: far-red ratios.Virtually no germination occurred in the dark. Our results are not consistentwith early reports that P. arundinacea germinationoccurredin the dark and was light insensitive, but they are consistent with a recentreport that it does not germinate in the dark and our own field and greenhouseobservations.
