Light-emitting diode (LED) lights have recently been applied in controlled environment agriculture toward growing vegetables of various assortments, including microgreens. Spectral qualities of LED light on photosynthesis in microgreens are currently being studied for their ease of spectral optimization and high photosynthetic efficiency. This review aims to summarize the most recent discoveries and advances in specific phytochemical biosyntheses modulated by LED and other conventional lighting, to identify research gaps, and to provide future perspectives in this emerging multidisciplinary field of research and development. Specific emphasis was made on the effect of light spectral qualities on the biosynthesis of phenolics, carotenoids, and glucosinolates, as these phytochemicals are known for their antioxidant, anti-inflammatory effects, and many health benefits. Future perspectives on enhancing biosynthesis of these bioactives using the rapidly progressing LED light technology are further discussed.
发光二极管（LED）灯最近已应用于受控环境农业，用于种植各种蔬菜，包括芽苗菜。目前正在研究 LED 光对芽苗菜光合作用的光谱质量，因其易于进行光谱优化和具有高光能利用率。本综述旨在总结 LED 和其他传统照明调制下特定植物化学物质生物合成的最新发现和进展，以确定研究空白，并为这一新兴的多学科研究和发展领域提供未来展望。特别强调了光的光谱质量对酚类、类胡萝卜素和硫代葡萄糖苷生物合成的影响，因为这些植物化学物质以其抗氧化、抗炎作用和许多健康益处而闻名。还进一步讨论了使用快速发展的 LED 照明技术增强这些生物活性物质生物合成的未来展望。
