Seed germination is a key process in the natural regeneration of plant populations and is mainly controlled by favorable temperature, water or light conditions. Light plays a critical role in determining the ability and rate of germination of photoblastic seeds. Furthermore, the regulation of seed germination by light involves not only
complicated physiological processes but also rigorous signal transductions and gene expression pathways. We summarized available data on the relationships between seed germination and other factors (i.e., light attributes, coupling of light and water/heat and phytochromes in seeds). To assess the effects of light on seed germination, we also comprehensively summarized the physiological reaction and light signal transduction mechanisms regulated by phytochromes in seed germination.
