Comparison of antioxidant contents of green and red leaf lettuce cultured in hydroponic systems under greenhouse, and conventional soil culture.
Hydroponic technologies have increased the cultivated area under greenhouses covered with UV filter polyethylene film. However, there is a concern about the antioxidant contents of lettuces produced under these systems. In this study, it was compared to the antioxidant contents of green and red leaf...
