光质对作物生长发育和植物化学成分有重要影响。此外，作为微型蔬菜种植的作物非常适合有人工照明的植物工厂，因为与完全生长的植物相比，它们含有更多的生物活性化合物。本研究的目的是评估具有不同红/蓝比率的宽光谱光对7种微绿植物的产量、形态和植物化学成分的影响。芥菜、萝卜、绿色罗勒、红阿马兰斯、韭菜、琉璃苣和豌豆苗在垂直耕作系统中在发射约2、5和9个单位的红/蓝比率（分别为RB 2、RB 5和RB 9）的三种光源下生长。芥末表现出最深刻的颜色反应。RB 9下的三种微型蔬菜和RB 2下的大蒜的产量提高。在三个微绿中，增加红光，下胚轴长度和叶片及子叶面积均显著增加。在RB 2下，总可溶性固形物（白利糖度）在4个微绿中减少。总酚含量和抗氧化能力降低RB 2下，在6和5微绿，分别。叶绿素受到轻微的影响，但总的类胡萝卜素含量降低RB 9在三个微型绿色。总的来说，光波长差异影响微绿的质量，而光谱带的小的相互作用增强了它们的植物化学成分。
Light quality exerts considerable effects on crop development and phytochemical content. Moreover, crops grown as microgreens are ideal for plant factories with artificial lighting, since they contain greater amounts of bioactive compounds compared to fully-grown plants. The aim of the present study was to evaluate the effect of broad-spectra light with different red/blue ratios on the yield, morphology, and phytochemical content of seven microgreens. Mustard, radish, green basil, red amaranth, garlic chives, borage, and pea shoots were grown in a vertical farming system under three light sources emitting red/blue ratios of about 2, 5, and 9 units (RB2, RB5, and RB9, respectively). Mustard exhibited the most profound color responses. The yield was enhanced in three microgreens under RB9 and in garlic under RB2. Both the hypocotyl length and the leaf and cotyledon area were significantly enhanced by increasing the red light in three microgreens each. Total soluble solids (Brix) were reduced in 4 microgreens under RB2. The total phenolic content and antioxidant capacity were reduced under RB2 in 6 and 5 microgreens, respectively. The chlorophylls were variably affected but total the carotenoid content was reduced in RB9 in three microgreens. Overall, light wavelength differentially affected the microgreens’ quality, while small interplays in spectral bands enhanced their phytochemical content.
