The research aims to determine how additional LED light spectra and doses affect the biomass and essential oil yield of Coriandrum sativum.
Plants grown for 9 weeks under varying light conditions.
Used combinations of red, blue, UV-A, green, and far red light.
Applied lighting durations of 4, 6, or 8 hours per night.
Measured essential oil composition and antimicrobial activity.
Analyzed the effects of different light treatments on biomass and oil yield.
F2 treatment produced the highest increases in fresh biomass (1.88x), dry biomass (1.92x), essential oil (2.69x), and linalool yield (4.84x).
Supplemental lighting significantly enhanced essential oil yield, with p < 0.001.
Oil samples showed varying antimicrobial effectiveness against tested strains.
Treatment F4 exhibited the strongest activity against Staphylococcus aureus, Escherichia coli, and Candida albicans.
