The aim is to evaluate how different LED light qualities affect the growth and essential oil yield of Tagetes erecta.
Cultivated Tagetes erecta in controlled growth chambers under three LED lighting treatments.
Applied varying ratios of red, blue, and white wavelengths for a constant 16-hour photoperiod over 101 days.
Conducted gas chromatography to analyze essential oil composition.
F2 treatment significantly increased fresh shoot yield and essential oil compared to F1 treatment.
Identified 30-31 compounds in essential oils with main constituents including (E)-β-ocimene, (E)-myroxide, and piperitone.
Essential oils displayed antimicrobial activity against Escherichia coli and Candida albicans.
