Abstract

Light emitting diode (LED) lighting is promising in the field of agricultural and secondary metabolites (SM) production. Features such as high-energy efficiency, long life, and flexibility in application make LEDs more suitable for the efficiency of SM production in the future than traditional lighting systems. In this study, we investigated the effects of LED and Glycine treatments on tropane alkaloids production by Hyoscyamus niger L. The use of LED light treatments started from the transplant stage, in such a way that, the pots were transferred to light boxes, light treatments on four levels (White, Blue, Red LED, and control in the greenhouse (C)) and Glycine foliar spraying was applied (0, 40, and 80 mg.L-1) in three stages with 10 days intervals. 14 days after the last treatment, yield efficiency, tropane alkaloids, phenol and flavonoids were examined. The highest total carbohydrate was observed when 80 mg. L-1 Glycine used under red LED light. Scopolamine and atropine assays with HPLC showed that LED lights and Glycine had an affirmative effect on the accumulation of these two important metabolites. The highest scopolamine (22.61 mg. g-1) and atropine were observed in BLED under Glycine at 40 and 80 mg. L-1.
