| Outline of Final Research Achievements |
In this study, the effects of dynamic variation of light intensity on antioxidant capacity (ORAC) and growth of lettuce leaves were investigated to acquire innovative knowledge on light environment control in plant production. The moderate variation of light intensity by supplementary lighting promoted lettuce growth. In addition, continuous irradiation with low PPFD had a potential to promote the growth but reduce the antioxidant capacity under constant daily cumulative PPFD. These results suggested that dynamic variation of light intensity might affect growth and antioxidant capacity of lettuce leaves.
