Plants are highly sensitive to variations in components of the visible light such as its wavelength, recently, the incorporation of LED (Lighting-Emitting Diode) artificial lighting of different wavelengths in horticulture has allowed to evaluate the responses generated in different levels of plant biology and use the synthesis of antioxidant compounds, whose consumption is beneficial for human health. The aim of this study was to evaluate the antioxidant response of lettuce plants to four wavelengths of LED visible light. Plants type Romaine cultivated until the end of their productive cycle were subjected to treatments of red, yellow, green and blue light; later, the kinetic response was characterized under red and yellow light for their capacity to stimulate the antioxidant synthesis. As main result, red light generated an antioxidant response in the fourth day which could be used for adding a functional component to lettuce plants. Yellow light could also be used, but the antioxidant response required at least six days. Despite the results, further research is required regarding the postharvest conservation of the antioxidant compounds and their usage for human health.

植物对可见光成分（例如其波长）的变化高度敏感，最近，园艺中并入了不同波长的LED（发光二极管）人工照明，可以评估在不同水平的植物生物学中产生的响应。使用抗氧化剂化合物的合成，其消耗对人体健康有益。这项研究的目的是评估莴苣植物对LED可见光的四个波长的抗氧化反应。培养到生产周期结束的长叶莴苣植物经过红，黄，绿和蓝光处理。随后，在红光和黄光下表征了它们的动力学反应，以刺激其抗氧化剂合成的能力。作为主要结果，红光在第四天产生抗氧化剂反应，可用于向莴苣植物添加功能性成分。也可以使用黄光，但抗氧化剂反应至少需要六天。尽管取得了这些结果，但仍需要对抗氧化剂化合物的采后保存及其对人体健康的用途进行进一步的研究。
