| Outline of Final Research Achievements |
Light is essential for plant growth, but too much light retards it. This is because excessive light inhibits photosynthesis irreversibly (photo-inhibition). During evolution, plants have developed mechanisms to avoid photo-inhibition. In this study, by applying chlorophyll fluorescence method, it was found that gymnosperms (conifers) have higher capacity of oxygen reduction in the thylakoid memebrane (Mehler reaction) than angiosperms. Angiosperms had increased capacity of cyclic electron flow around photosystem I.
