Nutritional quality, mineral and antioxidant content in lettuce affected by interaction of light intensity and nutrient solution concentration.

ABSTRACT: Light and nutrient are important factors for vegetable production in plant factory or greenhouse. The total 12 treatments which contained the combination of four light intensity (150, 250, 350 and 450 μmol · m^-2 · s^-1) and three nutrient solution concentration (NSC) (1/4, 1/2, 3/4 strength NSC) were established for investigation of lettuce growth and quality in a growth chamber. The combination of light intensity and NSC exhibited significant effects on photosynthetic pigment, nutritional quality, mineral content and antioxidant capacity. That a higher light intensity were readily accessible to higher chlorophyll a/b showed in lettuce of treatment of 350 μmol · m^-2 · s^-1 × 3/4NSC and 450 μmol · m^-2 · s^-1 × 1/4NSC. Lower tota
