Seawater has been applied to cultivate several crops like rice, wheat as one of eco-friendly material due to its enriched nutrients and minerals or induction of disease resistance. Lycium chinense was harvested after one or two times treatments of 15%, or 30% seawater on mid-August or September. Lycium chinense was analyzed its physical and physiological functions. Compared to those of conventional Lycium chinense, 30% seawater treated plant showed significantly higher ash content, mineral content such as K, P, Mg, Na, Fe, Zn but lower reducing sugar content. In addition, seawater treated plant had higher amount of total phenol, flavonoid, carotenoid, and antioxidant than those of conventional one. Among treatments, 30% seawater resulted in higher quality plant than 15% seawater. Plant quality was the excellent by 2 times with 15% seawater on September or 1 time with 30% seawater on November. These result indicated that seawater of 15~30% concentration was applicable as an eco-friendly material to cultivate Lycium chinense.
