Different LED light spectra (LS) are absorbed by different plant photoreceptors and can control biomass and plant secondary metabolite synthesis. In this study, the effects of continuous-spectrum LED lights (red, blue, white, red + blue, and 12 h blue + 12 h red) on the production value, antioxidant compounds, and biomass of basil ( L.) microgreens (Red Rubin, Violeto, and Kapoor cultivars and the Ablagh genotype) were investigated. The results showed significant effects of LS on cultivar (Cv) and the interaction of LS and Cv on the studied traits. The highest quantitys of chlorophyll a, total chlorophyll, and nitrate were obtained in Violeto under blue lighting. Red lighting enhanced starch synthesis in Red Rubin and flavonoids in the Violeto Cv. The highest biomass (4.54 kg m) was observed in the Ablagh genotype and the highest carbohydrate synthesis in Violeto Cv in the red + blue treatment. The highest anthocyanin content (26.33 mg 100 g FW) was observed for Red Rubin Cv under 12 h blue + 12 h red light. The greatest antioxidant capacity (83.57% inhibition), the highest levels of phenolic compounds (2027.25 mg GA 100 g FW), vitamin C (405.76 mg 100 g FW), proline, antioxidant potential composite index (APCI), and the greatest production values were obtained for the Ablagh genotype under blue lighting. Taken together, the experiment findings indicate that growing the Ablagh genotype under continuous blue lighting can increase the antioxidant capacity, phenolic compounds, and vitamin C and that this LED light spectrum can be used as a practical method to produce basil microgreens with high nutritional health value.
不同的LED光谱（LS）被不同的植物光感受器吸收，并可控制生物量和植物次生代谢物的合成。在本研究中，研究了连续光谱LED灯（红色、蓝色、白色、红色+蓝色以及12小时蓝色+12小时红色）对罗勒（L.）微型蔬菜（红鲁宾、紫罗兰和卡普尔品种以及阿布拉格基因型）的产值、抗氧化化合物和生物量的影响。结果表明，光谱对品种（Cv）以及光谱与品种的相互作用对所研究的性状有显著影响。在蓝光下，紫罗兰品种的叶绿素a、总叶绿素和硝酸盐含量最高。红光增强了红鲁宾品种的淀粉合成以及紫罗兰品种的黄酮类化合物合成。在红色+蓝色处理中，阿布拉格基因型的生物量最高（4.54 kg m），紫罗兰品种的碳水化合物合成最高。在12小时蓝色+12小时红色光照下，红鲁宾品种的花青素含量最高（26.33 mg 100 g FW）。在蓝光下，阿布拉格基因型的抗氧化能力最强（83.57%抑制率），酚类化合物含量最高（2027.25 mg GA 100 g FW），维生素C含量最高（405.76 mg 100 g FW），脯氨酸、抗氧化潜力综合指数（APCI）最高，产值也最高。综上所述，实验结果表明，在连续蓝光下种植阿布拉格基因型可以提高抗氧化能力、酚类化合物和维生素C的含量，并且这种LED光谱可作为一种实用方法来生产具有高营养健康价值的罗勒微型蔬菜。
