光照光谱是决定人工栽培条件下药用植物生物量生产和次生代谢积累的关键因素之一。采用400-700 nm宽波段的蓝光（10%红、10%绿、70%蓝）、绿光（20%红、10%绿、30%蓝）和富红光（30%红、10%绿、20%蓝）培养榕树和高山木幼苗。与红、绿光光谱相比，蓝光光谱下青松幼苗直径、细根长、叶面积、生物量、地上部养分(N)和磷浓度均较低。赤光光谱下，叶黄素和皂苷含量显著高于叶黄素、叶绿素、可溶性糖和淀粉含量。赤叶莲容易受到蓝光光谱的负面影响，但赤叶莲适合在宽带宽的红光光谱中产生黄酮类和皂苷。
Lighting spectrum is one of the key factors that determine biomass production and secondarymetabolism accumulation in medicinal plants under artificial cultivation conditions. Ficus hirta and Alpinia oxyphylla seedlings were cultured with blue (10% red, 10% green, 70% blue), green (20% red, 10% green, 30% blue), and red-enriched (30% red, 10% green, 20% blue) lights in a wide bandwidth of 400-700 nm. F. hirta seedlings had lower diameter, fine root length, leaf area, biomass, shoot nutrient (N) and phosphorus concentrations in the blue-light spectrum compared to the redand green-light spectra. In contrast, A. oxyphylla seedlings showed significantly higher concentrations of foliar flavonoids and saponins in red-light spectrum with rare responses in N, chlorophyll, soluble sugars, and starch concentrations. F. hirta is easily and negatively impacted by blue-light spectrum but A. oxyphylla is suitably used to produce flavonoid and saponins in red-light spectrum across a wide bandwidth.
