Different qualities of supplemental light emitting diode (LED) light were applied to enhance growth characteristics and bioactive compounds of buckwheat (Fagopyrum esculentum) seedlings. The wavelength of the LED lights was blue 470nm, red 660 nm, blue + red (BR), far-red 740 nm. The LED light treatments were applied after the emergence of two true leaves for 15 days and a control experiment was done without supplemental light. In this study, it is shown that supplemental BR light significantly increased plant height, node number, leaf number and plant fresh weight compared to control treatment. Far-red light increased stem length among the treatments. On the other hand, ascorbic acid, anthocyanin, total phenolic, and chlorophyll contents were significantly increased of buckwheat seedling grown under BR light compared to control.
