| Research Abstract |
The effects of light quality on the flowering of Gypsophila paniculata were investigated using light-emitting diodes (LEDs). Flowering and flower budding were observed under long-day conditions with far-red (FR), while no flowering was observed under short-day conditions. Promotion of flowering and flower budding was increased under FR supplemented with red R compared to FR alone. Although generally R inhibits flowering in long-day plants, a certain intensity of R may be necessary for effective promotion of flowering. In contrast, blue (B)supplementation of FR was not effective in inducing flowering and flower budding.
