(A) Chlorophyll content and (B) flavonoids content for lettuce plants grown under LED lights with different RB ratios (closed symbols) or under fluorescent light (open symbols). Mean values ± SE (45 replicate plants for chlorophyll content, 27 replicate plants for flavonoids content). Different letters indicate statistically significant differences at P ≤ 0.05.
