[Objective] This study was conducted to investigate the effects of light quality on growth and quality of Chinese kale(Brassica alboglabra Bailey). [Method]Chinese kale was grown in hydroponic under three different Light Emitting Diode(LEDs) conditions [red∶blue=8∶1(8R1B), red∶blue=6∶3(6R3B) and red∶green∶blue=6∶2∶1(6R2G1B), 12 h light, 50 μmol/(m2·s)]. Then its growth and quality indices including root and shoot fresh weight and dry weight, concentrations of soluble protein, vitamin C, nitrate, soluble phenols, flavonoids, soluble sugar, free amino acids, and activity of nitrate reductase were measured. [Result] There was no significant difference in plant height, diameter of flower stalk and leaf number among three LED treatments. The fresh weight of shoot, root and plant in 8R1 B and 6R2G1 B was significantly higher than in 6R3 B. The dry weight of shoot and plant in 8R1 B was significantly higher than in 6R3 B. The concentrations of vitamin C, soluble protein and soluble sugar in flower stalk of 6R3 B treatment were significantly higher than those in 8R1 B and 6R2G1 B, while there was no remarkable difference in concentrations of reducing sugar, soluble phenol, flavonoids and free amino acid among the three treatments. The nitrate concentration in flower stalk of 6R3 B was significantly lower than in the other two treatments, and the activity of nitrate reductase in6R3 B was significantly higher than in the other two treatments. [Conclusion] The LED treatment of red:blue=6:3 was more suitable for the growth of Chinese kale.
