In contrast, <em>A. oxyphylla</em> 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. <em>F. hirta</em> is easily and negatively impacted by blue-light spectrum but <em>A. oxyphylla </em>is suitably used to produce flavonoid and saponins in red-light spectrum across a wide bandwidth.</p>}, number={2}, journal={Notulae Botanicae Horti Agrobotanici Cluj-Napoca}, author={ZHOU, Changwei and SHANG, Chongfei and CHEN, Feiyu and BAO, Junzhou and YU, Lifei and GUO, Peng}, year={2021}, month={Jun.}, pages={12314} }
