With both common and Tartary buckwheat species, this study was aimed at producing new commercially useful bio-materials with higher nutritional and medicinal value due to higher components for health promotion and diseases care. In common buckwheat sprouts, it was found that root length at $20^{circ}C$ was longer (5.93 cm) than at 25 and $30^{circ}C$, whereas the hypocotyls length, fresh weight of each sprout, and whole fresh weight showed the highest value at $30^{circ}C$. For Tartary buckwheat, the root length, hypocotyl length and fresh weight of each sprout and whole fresh weight were also the highest at $30^{circ}C$. Common buckwheat (Suwon No.1) and Tartary buckwheat (KW45) sprouts cultured at $20^{circ}C$ showed that hypocotyl length, fresh weight of each sprout, and whole fresh weight in the control were higher than those sprouts treated with 5% and 10% deep sea water (DSW), while the sprouts cultured at $30^{circ}C$ showed were significantly longer hypocotyls than the control or 5% DSW treatment.
