Notes: Ecological Implications of Phytochrome-Mediated Seed Germination in Red Alder
Abstract:Germination of red alder (Alnus rubra Bong.) seed responded to red and far-red light in a reversible fashion implicating the role of phytochrome in germination processes. Additional experiments designed to elucidate the ecological importance of light sensitivity were performed. Germination was strongly inhibited under conditions of low irradiance (simulating the effects of seed burial) and when broadleaf foliage filtered incoming light, (simulating the presence of a vegetative canopy). These results suggest that manipulation of herbaceous vegetation or degree and type of soil disturbance may be useful tools for establishment or control of red alder. Forest Sci. 29:734-738.
