Abstract
Flowering control with light quality is now attracting attention as LEDs become more popularized and genetic researches make more advancement. In some model plants used in experiments, a mechanism of flowering in long-day plants promoted by far-red light has been revealed. In addition, a research concerning effects of light quality in the flowering control of cut flowers conducted in Tohoku district reveled that the long-day treatment with far-red light is effective in promoting flowering of Eustoma and stock.
