| Outline of Final Research Achievements |
Plant materials and experimental methods to demonstrate seed germination response to light and the importance of this response in natural condition were searched for high school education. We collected seeds of several ruderal plants familiar to us, most of which showed positive photogermination, and seed germination of Plantago virginica and Plantago asiatica was reversibly regulated with short red and far-red light pulses repeatedly applied, indicating involvement of phytochrome. We also made an irradiation box to show that natural light transmitted through a green leaf could reversibly inhibit Plantago seed germination. Experiments using seeds of wild plants and natural light may help students to consider about the biological role of phytochrome regulation.
