Fig. 1. Light-inducible germination of photoblastic rice seeds: (A) germination modes under continuous white light () or in darkness (•), (B) germination frequencies under a pulse of red (R) and far-red (FR) light and alternating irradiation of R and FR light, (C) germination responses to a pulse of R () and FR (•) light after the onset of dark imbibition, and (D) germination responses to different fluence rate of white light depending on dark imbibition period. After dark imbibition for 1 (•), 3 (), 5 (), and 10 d () at 30°C, the seeds were exposed to different periods of white-light irradiation and then kept in darkness for 6 d at 30°C.
