Seed dormancy in <i>Trillium camschatcense</i> (Melanthiaceae) and the possible roles of light and temperature requirements for seed germination in forests

Abstract

Seeds of T. camschatcense have deep simple double MPD and requirements for radicle emergence: darkness and constant temperatures. Ecologically, edges of forests may be deleterious for germination of the species due to increased light and to higher temperature fluctuations as compared to the interiors of forests. Thus, these specific requirements may play an important role in reducing seed germination of this plant at forest edges.
